Our Purpose
At SentinelOne, we are driven by a clear purpose: to give the advantage to those who secure our future. As AI reshapes how organizations build, operate, and innovate, the responsibility to protect them becomes more critical than ever. When you join SentinelOne, your work helps protect global enterprises, critical infrastructure, and the technologies shaping tomorrow. If you are motivated by meaningful challenges and want your impact to be real, measurable, and global, you will find purpose here.
About Us
SentinelOne is a company at the intersection of AI and security, pioneering a new operating model for cybersecurity. Our AI-native platform unifies protection across endpoint, cloud, identity, data, and AI systems to deliver autonomous detection and response with clarity and speed. By combining real-time analytics, intelligent automation, and a unified data foundation, we reduce noise, simplify complexity, and empower security teams to focus on what truly matters.
Our teams are builders, problem-solvers, and innovators committed to shaping the future of security. If you are excited to solve hard problems alongside talented, mission-driven people, we invite you to help us build a safer future for humanity.
What Are We Looking For?
We’re looking for people who are relentlessly curious and committed to continuous learning. AI is reshaping every function across our business, and we enable every team member, regardless of role or level, to build fluency in AI tools and concepts. Those who thrive here actively seek out new solutions, experiment thoughtfully, and apply what they learn to drive better, faster, smarter outcomes.
We are seeking an experienced Staff Platform Engineer / Software Engineer who will serve as a technical leader with dozens of engineering teams. You are someone who enjoys bridging the gap between software engineering and systems architecture, and not just managing infra, but building Internal Developer Platform (IDP) on Kubernetes, and APIs that enable scalability, efficiency, productivity, and developer joy. You are a "doer" who can pivot from writing high-quality production code to influencing the architectural direction of our CI/CD pipelines and service catalogs (e.g., Backstage), as well as be the next frontier of Generative AI integration.
Our Developer Experience (DevEx) organization’s mission is to partner with SentinelOne engineering teams to accelerate the velocity of software delivery through continuous innovation and standardization. We are building a platform that serves nearly 1,000 engineers to release services and features to our customers, making it easy to move from POC to production safely and quickly. We're also transforming our CI/CD from a traditional pipeline into an AI-driven engine - you will help us build a platform where AI proactively helps developers write & ship code, generates high-coverage test suites on the fly, and performs the first pass of PR reviews with human-level context.
What Will You Do?
- Partner with Engineers, Build & Automate: The engineering teams are our primary customers - you will be working with them to understand their pain points and find long term solutions.
- You will be building the IDP as the "Golden Path", and tools that improve the quality of life and streamlining the development process for the teams, so that they can build without having to worry about the underlying infrastructure.
- You will be also building scalable solutions in collaboration with other infrastructure teams.
- Modernize the Stack: Collaborate with architects to evaluate and implement modern tools (e.g., ArgoCD, GitHub Actions) and deployment strategies (Canary, Blue/Green).
- Lead the AI-Driven CI/CD Shift: Architect and implement AI-powered workflows that assist in code generation, automated testing, and intelligent PR analysis to eliminate developer friction.
- Operational Ownership: Identify causes of toil across engineering orgs and eliminate them through automation, enhancing overall system reliability and developer satisfaction.
- Cross-Functional Influence: Partner with Product, Security, and Finance teams to align technical roadmaps with business value and customer needs. You will influence strategy and ensure our platform is as lean as it is powerful.
- Impact: You will participate in the full software development lifecycle, including requirements analysis, architecture design, coding, testing, and deployment.
- Deal with global scale: Our security SW products protect 15,000 enterprise and government clients across the globe, incl. 4 of Fortune 10, and process 9+ Petabytes of data daily and 3+ Trillion security events across multiple AWS/GCP regions and GovCloud, supported by a large Kubernetes control plane with 80+clusters and tens of thousands of nodes.
Our stack: Go, Python; Kubernetes, Docker, AWS, GCP, FedRAMP; GitHub Actions, ArgoCD; GitHub Enterprise; depending on the requirements of the service for communication, we use Kafka, REST API, GraphQL, gRPC, etc.; Postgres, MongoDB, Redis, ClickHouse; Prometheus/Thanos, Grafana
What Skills and Knowledge Will You Bring?
- Demonstrated proficiency in Go or Python. Experience in the full SDLC, from requirements to production-ready code
- Experience with AWS and/or GCP. Knowledge of Kubernetes or similar orchestration systems
- Experience with CI/CD tooling at scale (e.g., GitHub Actions, ArgoCD, Jenkins etc.) and GitOps approach
- Strong experience with Terraform, Pulumi, or similar IaC frameworks
- Familiarity with DevEx fundamentals, including Service Catalogs (Backstage), REST APIs, or gRPC
- Familiarity with both SQL (Postgres) and NoSQL (MongoDB, ClickHouse, or Redis)
- You are passionate about (and ideally have experience in) integrating LLMs and AI agents into the developer workflow to drive productivity
- Excellent problem-solving skills, strong ownership and accountability, with proven experience driving large, impactful projects
- Strong communication skills and ability to articulate technical concepts and influence engineering direction across teams, departments, and stakeholders in multiple time zones

What Success Looks Like
Build and improve the experiences that customers use before and after purchase, with a strong focus on speed, quality, and AI-assisted engineering. You will help shape the web and app journeys that directly affect how customers discover deals, complete purchases, and manage their orders.
We Are Interested In
- Candidates who like solving real product problems, not just writing code.
- People who learn quickly and can work through changing priorities.
- Engineers who are proactive, curious, and easy to trust with ownership.
- Candidates who can explain how they think, not only what they have built.
What We Offer
- Impact at scale: Help shape the experiences millions of customers use before and after purchase, with real influence on how the product evolves.
- Ownership, not just delivery: You’ll own key journeys end to end
- AI‑first environment: Full access to AI coding tools, including a Claude Max plan and other approved assistants, integrated into your everyday workflow.

Share this job
At JetBrains, code is our passion. Ever since we started, back in 2000, we have been striving to make the strongest, most effective developer tools on earth. By automating routine checks and corrections, our tools speed up production, freeing developers to grow, discover, and create.
The Version Control Experience team is part of the IntelliJ Platform department. We focus on improving the version control workflows across all JetBrains IDEs. From the moment a user clones a project to exploring its branches and reviewing changes, our mission is to make working with Git and other VCS tools feel smooth, fast, and reliable. Our work spans multiple IDEs and directly impacts millions of users.
We’re looking for a Kotlin or Java developer to help us improve the VCS experience across JetBrains IDEs.
In this role, you’ll:
- Improve core workflows such as cloning projects, switching branches, resolving conflicts, and viewing history.
- Develop and maintain VCS integration components used across multiple IDEs.
- Enhance integrations with GitHub and GitLab, making them more seamless and feature-rich.
- Contribute to architecture and performance improvements within the VCS subsystem.
- Work closely with UX designers and other product teams to polish and improve the VCS experience.
- Have an opportunity to work on features used by millions of developers every day, including your teammates and colleagues
- Have freedom of ideas - you are always encouraged to suggest and implement new features and improvements to existing workflows
We’d be happy to bring you on board if you:
- Have strong development experience with Kotlin or Java.
- Are familiar with Kotlin coroutines and asynchronous programming.
- Are familiar with web-based APIs (REST, GraphQL).
- Are comfortable working with legacy code and gradually improving it.
- Are interested in developer tools and care about their usability.
- Are open to working with UI (Swing), or already have experience doing so.
- Strive to write clean, efficient, and maintainable code.
- Enjoy exploring how things work under the hood and aren’t afraid of technical complexity.
We would be especially thrilled if you:
- Are a power user of Git. If you’re comfortable with rebase workflows, cherry-pick, resolving complex merge conflicts, and working with staging areas interactively, you’ll feel right at home.
- Understand Git internals such as the index, reflog, low-level merge strategies, or how Git represents history.
- Have experience with IntelliJ plugins or developer tools.
- Are familiar with UI/UX best practices.
- Experience with mobile development in Android
About the Team:
We’re a relatively small, distributed team based in Munich, Amsterdam, Berlin, and Belgrade. We keep meetings minimal and collaboration focused and informal. We value empathy, clarity, and initiative – and we’re looking forward to welcoming a new teammate.
Why join JetBrains?
- Strong base salary. We offer competitive pay that reflects your skills and experience.

About ShipMonk
ShipMonk isn't just a 3PL; we're a growth partner for merchants. We provide cutting-edge technology and a network of owned and operated fulfillment centers that empower high-growth ecommerce and DTC brands to stress less and grow more. With over 2,500 employees across five countries, we're on a mission to revolutionize fulfillment by providing everything from the fastest click-to-delivery and real-time inventory to custom solutions—all with a merchant-first mindset.
Why ShipMonk?
We believe in building for the long term, and our success is powered by five key differentiators that help us become true partners to our merchants.
● Global Fulfillment Network: Our 12+ owned and operated fulfillment centers span the US, Canada, Mexico, the U.K., and Mainland Europe. We never outsource, ensuring quality and consistency.
● Proprietary Technology: We've eliminated the need for tribal knowledge with our AI-powered platform. It provides a real-time, unified view of inventory and orders, giving our merchants the control and visibility they need to succeed.
● Unrivaled Support: We provide hands-on, "mom and pop" support with a global reach. Our dedicated teams are on-site at every fulfillment center, ready to jump into action.
● Transparent Pricing: We believe in honest, long-term partnerships. Our all- inclusive pricing means predictable costs, with no hidden fees or surprises.
● Committed to the Future: We invest over $10 million annually in research and development to ensure our technology and services continually evolve, helping merchants plant roots with a partner who is here to stay.
Our values are the heart of our culture. We're looking for individuals who embody these principles every day.
● Merchant-first: We handle the logistics so our merchants can focus on what they do best—growing their business.
● People make ShipMonk: We believe in our team and invest in our people.
● Change the score: We challenge the status quo, constantly innovating and improving.
● Get sh*t done: We're a fast-paced, high-growth company that values action and results.
We are ShipMonk, and we provide logistics services in order fulfillment. Our main business is in the USA, but our modern platform is built by the Product Development team in Prague.
Here at ShipMonk, we process up to 100,000 orders per day in our peak season. Our book of business has more than 1,500 clients which are small and medium e-shops, mostly based in the US. We offer the ShipMonk platform as the solution for the whole process. It covers everything from stocking the items to shipping the ready packages to all corners of the world!
We are looking for a skilled PHP Developer to join ShipMonk! This is an exciting opportunity to join our Product Development Team located in Prague. Please take a look at the details below.
Tech Stack:
- PHP 8.5
- Symfony 7
- Docker
- Kubernetes
- Doctrine ORM 3
- RabbitMQ
- MySQL 8
- GraphQL
- Elasticsearch
Our teams:
- Warehouse: optimization and automation of warehouse processes
- Internals: refactoring, tech-debt reduction, and legacy code removal
- Customer features: development of the functions of the existing web environment
- Frontend: TypeScript clients in React, E2E
- DataScience: AI, DWH, data-governance, prediction, and optimization, business intelligence
- QA: acceptance-criteria testing
- DevOps: Infrastructure, Kubernetes, CI/CD management and Cloud platform management
- Technical Product Managers: Asana & project management
What does it look like and what we are proud of:
- The main backend application provides a REST-like API for several types of clients (web, autonomous robots, iOS picker devices, microcomputer packers, automatic conveyors and more).
- We have the rest of the applications and clients in monorepo for easier CI checks, code sharing, etc.
- We have all services completely dockerized for local development. We deploy builds to a hosted Kubernetes cluster in AWS with a single click on the Argo CD several times a day.
- Each MR can be deployed on a separate cluster for one-button testing in the CI, so we don't argue about a test environment.
- We have set up a lot of checks in GitLab CI (PHPStan, PHP_CodeSniffer, PHPUnit, lint, editorconfig-check, migration check, security scans, renovate-bot).
- In addition to static analysis, we also do a two-round review and the operation is also verified by the QA team and E2E cypress tests.
- We have more than 15 000 database integration tests with the thoughtful creation of independent datasets for each test, ie no shared data that breaks forever.
- We directly automate the agreed coding-rules, so we have already written dozens of our own phpstan rules and coding-standard sniffs.
- We think about concurrence and design the application to withstand race conditions, which is not exceptional in a warehouse environment.
- The application is supported by DataDog, Sentry, and Opsgenie.
- Our database has grown to terabyte size, so even the optimization of SQL queries is becoming the daily bread of all of us.
- We deal with HA, failover, and autoscaling, almost no service runs for us only once.
- Having experienced colleagues is our huge advantage.
- We automatically generate documentation of all our REST-like endpoints.
- We open-source some of our best tools and contribute back to the OS community.
- We utilize code coverage.
If you like what we do, and our "story" got you interested, we look forward to seeing your resume, profile, story, or anything else you might have! There are no limits to creativity. Our Recruiter will get back to you as soon as possible. We look forward to hearing from you!
ShipMonk is an equal opportunity employer. We value diversity and do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
