Manager, Software Engineering, Publishing Engagement - Publishing Platform

Riot Games · Seoul, Korea

Publishing Platform Seoul, Korea Posted May 6, 2026

Riot Games was established in 2006 by entrepreneurial gamers who believe that player-focused game development can result in great games. In 2009, Riot released its debut title League of Legends to critical and player acclaim. As the most played video game in the world, over 100 million play every month. Players form the foundation of our community and it’s for them that we continue to evolve and improve the League of Legends experience.

We’re looking for humble but ambitious, razor-sharp professionals who can teach us a thing or two. We promise to return the favor. Like us, you take play seriously; you’re passionate about games. We embrace those who see things differently, aren’t afraid to experiment, and who have a healthy disregard for constraints.

That's where you come in.

Riot Engineers bring deep expertise in specific technical areas while embracing opportunities to work across broader domains. As a Manager, Software Engineering, you’ll lead from the front — working alongside your team through every phase of the software development and operations lifecycle. You’ll combine hands-on technical leadership with mentorship and coaching to drive both team growth and product excellence.

As the Manager, Software Engineering, in the Publishing Platform’s Publishing Engagement team, you’ll lead the engineers who design, build, and operate platform services that enable game content delivery and power player-facing experiences across and beyond games. You’ll partner with game developers across Riot, central technology groups, and legal and business teams in Korea to make smart decisions, maintain a high quality bar, and operate efficiently in service of players in Korea and around the world.

Your deep understanding of technical systems and engineering workflows will help shape how the team builds, operates, and scales our services. You’ll participate in key technical decisions, guide documentation and process improvements, and coach engineers to deliver cohesive, multi-platform experiences that power all of Riot’s games. Your leadership will enable the team to operate with clarity, discipline, and agility — staying aligned and delivering lasting impact for players.

You will report to the Sr Manager, Software Engineering, who oversees multiple teams under the Meta Game Services initiative.

Responsibilities:

Team Leadership & People Management

Manage a team of 4–5 Software Engineers; coach, mentor, and support their growth while driving strong performance and positive results
Own the interviewing and onboarding process for new engineering team members
Build healthy relationships with engineering/QA teams across Riot globally to foster collaboration and shared learning

Technical Leadership & Hands-on Involvement

Stay hands-on with the team’s technology, overseeing technical design and deliverables in partnership with the team’s technical leadership
Engage regularly with the codebase through reviews and non-critical contributions to stay close to the team’s work
Drive the technical vision and roadmap by collaborating closely with engineers — contributing to design reviews, aligning priorities, and ensuring the right people and skills are in place to deliver results
Maintain accountability for the technical health and long-term sustainability of the team’s products

Execution & Cross-functional Collaboration

Lead the breakdown and execution of multi-month projects, partnering across disciplines and other engineering teams to deliver impactful outcomes
Collaborate with Product Leads, Delivery Leads, and Engineering/QA Leads within the team and across Meta Game Services and Publishing Platform to align on execution plans and priorities
Align with service teams within Meta Game Services and across the Publishing Platform organization to drive consistency in tech standards, tooling, and best practices

Required Qualifications:

Bachelor's or Master’s degree in Computer Science or a related field, or equivalent professional experience
5+ years experience as a Software Engineer, including hands-on experience delivering live or shipped web applications
2+ years experience directly leading an engineering team either as an Engineering Manager or Technical Lead
Deep front-end expertise with TypeScript/Javascript, React, CSS-in-JS, and modern frameworks like Next.js
Extensive back-end experience with Java and Spring Boot, combined with strong fundamentals in software engineering (data structures, algorithms, concurrency, OOP) and experience designing scalable systems using RESTful APIs, event-driven microservices, and modern web architecture patterns
Proven track record of improving engineering discipline — driving better documentation, thoughtful tech design processes, and structured proposals for technical improvements, with a strong understanding of the full product lifecycle from design to deployment and operations, and the ability to apply MVP principles effectively
Able to clearly communicate technical concepts and decisions across disciplines, helping align engineers, designers, and product managers
Experience managing engineers and actively participating in their growth and development
Experience recruiting candidates and growing an engineering team
Experience with distributed systems, microservices, and software at a high scale
Experience operating and maintaining live services, including handling emergent issues and on-call troubleshooting
Fluency in Korean and professional working proficiency in English, as the position involves being based in Seoul while engaging with global teams across Riot

Desired Qualifications:

Experience developing using cloud infrastructure (such as AWS, GCP), using containers and orchestration (such as Docker, Kubernetes), managed using infrastructure as code (such as Terraform)
Experience with CI/CD pipelines (such as GitHub Actions, Jenkins, Netlify)
Experience with relational databases (such as MySQL)
Experience with event driven architectures and technologies (such as Kafka)

Don’t forget to include a resume and cover letter. We receive a lot of applications, but we’ll notice a fun, well-written intro that shows us you take play seriously.

You thrive in ambiguity and enjoy partnering with others to shape vague requirements into clear roadmaps with pragmatic tradeoffs.
You take shared accountability for the end-to-end journey; communicating progress, surfacing risks early, and following through to ensure your work creates measurable value.

You demonstrate strong judgment under uncertainty.

You prioritize based on long-term impact, over short-term noise, making deliberate decisions when information is incomplete.
You explicitly weigh tradeoffs like speed vs. quality and remain agile enough to adjust your approach thoughtfully as new information/data emerges.

You lead through clarity and active listening.

You reduce ambiguity for the team by asking the right questions upfront, tailor your communication to your audience, document your decisions, and bring helpful structure to complex discussions.
You provide thoughtful, evidence-based feedback when needed and align behind decisions once they are made.

You collaborate early, instead of solving in isolation.

You build trust across the organization by listening first and navigate conflicting needs with empathy, creating buy-in around priorities and scope.
You navigate technical tensions productively, disagreeing thoughtfully while maintaining momentum and strengthening professional relationships.

You fall in love with the problem, not the solution

You build for the long run, looking beyond immediate tasks to understand root causes, second-order effects, and the long-term health of our ML ecosystem.
When something breaks, you don’t just patch it; you seek structural improvements that prevent recurrence and elevate the technical bar for the entire organization.

You prioritize customer impact and take action to make it real.

You prioritize effective solutions that drive business impact over technical elegance, spotting opportunities that others might overlook.
You have the initiative to turn ideas into outcomes and the agency to identify and fix gaps, even when they aren’t yet on the formal roadmap.

Senior Solutions Engineer

Cloudflare · Hybrid

Solution Engineering Seoul, South Korea Posted Apr 21, 2026

About Us

At Cloudflare, we are on a mission to help build a better Internet. Today the company runs one of the world’s largest networks that powers millions of websites and other Internet properties for customers ranging from individual bloggers to SMBs to Fortune 500 companies. Cloudflare protects and accelerates any Internet application online without adding hardware, installing software, or changing a line of code. Internet properties powered by Cloudflare all have web traffic routed through its intelligent global network, which gets smarter with every request. As a result, they see significant improvement in performance and a decrease in spam and other attacks. Cloudflare was named to Entrepreneur Magazine’s Top Company Cultures list and ranked among the World’s Most Innovative Companies by Fast Company.

At Cloudflare, we’re not looking for people who wait for a polished roadmap; we’re looking for the builders who see the cracks in the Internet that everyone else has simply learned to live with. We value candidates who have the instinct to spot a "normalized" problem and the AI-native curiosity to create a solution using the latest tools. Our culture is built on iteration, leveraging AI to ship faster today to make it better tomorrow, while ensuring that every improvement, no matter how small, is shared across the team to lift everyone up. If you’re the type of person who values curiosity over bureaucracy, and that AI is a partner in solving tough problems to keep the Internet moving forward, you’ll fit right in.

Available Location: Seoul, South Korea

What you’ll do as a Senior Solutions Engineer

You are the technical lynchpin through the entire sales cycle - pre and post sales. You will work closely with our prospects and customers to educate, empower, and ensure their success on the Cloudflare platform. Your technical expertise in Cloudflare’s global distributed network and technology will allow you to find best-fit solutions for prospects, to train and onboard new customers via video-conference or in person, through documentation, and to support the long-term success of the customer. As a subject matter expert on web/mobile security and performance, you are a trusted source for developing new firewall rules from log files, crafting performance caching and delivery strategies, and creating or repurposing internal tools and scripts for customers.

As a Senior Solutions Engineer, you are the technical customer advocate within Cloudflare. To aid your customers, you will work closely with every team at Cloudflare, from Sales and Product, through to Engineering and Customer Support. Your goal of customer success should drive you through the entire organization as you seek out and create scalable solutions for your customer’s needs.

What we look for in our Solutions Engineers

Our Solutions Engineers come from a wide range of backgrounds: financial consulting, engineering, software development, product management, customer support, and project delivery. We're serious about building a diverse team. When hiring we look for diversity of experience combined with genuine curiosity for our technology.

Ultimately, you are passionate about technology and have the ability to explain complex technical concepts in easy-to-understand terms. You are naturally curious, and an avid builder who is not afraid to get your hands dirty. You appreciate the diversity of challenges in working with customers, and look forward to helping them realize the full promise of Cloudflare. On the Solutions Engineering team, you will find a collaborative environment where everyone brings different strengths and jumps in to help each other.

Responsibilities

As critical members of Cloudflare’s sales team, Solutions Engineers drive technical discussions and implementations to help generate new business, expand existing business, and keep our customers happy.
In business generation and expansion, you’ll be tasked with qualification of prospect and customer use cases, technical requirements discovery, leading demonstrations, solution identification and design, and collaborative work on proofs-of-concept (PoCs).
For our existing customers, Solutions Engineers are part of a dedicated account team that advises the customer on technical best practices, implementation of Cloudflare products and features, and strategic guidance on internet security and performance.
The role requires 20-50% travel to attend meetings with prospects or customers, attend conferences and other industry events, and to collaborate with your Cloudflare teammates.

Requirements

Demonstrated experience with a scripting language (e.g. Python, JavaScript, Bash, Lua, Go) and a desire to expand those skills.
Expertise in internet technologies: OSI Model layers 1-7, BGP, GRE, TCP/UDP, DNS (authoritative and recursive), HTTP(S), SSL / TLS.
Familiarity with Zero Trust Framework and SASE related concepts.
10 years plus of experience in a customer-facing sales or consulting role.
Technical curiosity and passion: Cloudflare is at the cutting edge of internet technology, and our Solutions Engineers are viewed as subject-matter experts. It’s incumbent on us to stay up to date not only with Cloudflare’s specific products, but with industry trends.
A focus on learning, teaching, collaboration, mentorship, and growth, not only personally but also within the team and company.
Aside from technical and collaborative skills, we place a high value on project management, relationship building, and EQ.

Desired

You've built web applications before, or contributed to existing web applications in a meaningful way.
You understand the role of a firewall, the difference between L3, L4, and L7 firewalls, and that ‘ACL’ doesn't always mean Anterior Cruciate Ligament.
You're not afraid of command-line interfaces, RESTful APIs, or analyzing HTTP request and response in a browser’s web inspector.
You can describe the differences between CSRF, XSS, and SQLi in detail, and Cloudflare's role in defending against them.
Understanding of, or experience with, regulatory requirements such a PCI DSS, HIPAA, and SOC-2.
Good communication skills in Korean and English
An undergraduate degree in Computer Science, Engineering or a related field. Reminder: this is not a strict requirement at all. Candidates from all walks of life are welcome.

Graduate-level degrees in Computer Science, Engineering or related fields. Reminder: this is not a strict requirement at all. Candidates from all walks of life are welcome.
Certifications

More About You

You can translate technical concepts and jargon for a wide variety of audiences: from systems engineers, to front-end developers, through to IT managers and C-levels in organizations.
You want to be constantly learning new things and teaching what you've learned to the broader team through internal and external blog posts, team demos, and product training sessions.
You have a knack for understanding problems and finding creative ways to solve them. Our product suite is ever-growing, and knowing how to identify which parts will solve a customer's particular problem is important.
You understand how to manage a project, work to deadlines, and prioritize between competing demands.

What Makes Cloudflare Special?

We’re not just a highly ambitious, large-scale technology company. We’re a highly ambitious, large-scale technology company with a soul. Fundamental to our mission to help build a better Internet is protecting the free and open Internet.

Project Galileo: Since 2014, we've equipped more than 2,400 journalism and civil society organizations in 111 countries with powerful tools to defend themselves against attacks that would otherwise censor their work, technology already used by Cloudflare’s enterprise customers--at no cost.

Athenian Project: In 2017, we created the Athenian Project to ensure that state and local governments have the highest level of protection and reliability for free, so that their constituents have access to election information and voter registration. Since the project, we've provided services to more than 425 local government election websites in 33 states.

1.1.1.1: We released 1.1.1.1 to help fix the foundation of the Internet by building a faster, more secure and privacy-centric public DNS resolver. This is available publicly for everyone to use - it is the first consumer-focused service Cloudflare has ever released. Here’s the deal - we don’t store client IP addresses never, ever. We will continue to abide by our privacy commitment and ensure that no user data is sold to advertisers or used to target consumers.
