Straight Arrow is on a mission to restore trust in the news by delivering fair, fact-based journalism in a media landscape that too often prioritizes outrage over accuracy. Our small but mighty technology team builds and maintains the platforms that makes this mission possible, from the SAN.com mobile apps to the web experience and the infrastructure that ties it all together. We move fast, build thoughtfully, and believe the right engineer can make an outsized difference.

The Role

We're hiring a Senior Software Engineer specializing in React Native development for our customer-facing mobile app, built and shipped in tandem with work on the Straight Arrow website. You will own the mobile codebase end-to-end — from the React Native and Expo layer all the way down to native bridges we've already built into iOS and Android.

This is a deeply hands-on role. We're looking for an engineer whose primary impact is the code itself: the architecture you choose, the patterns you set in the codebase, the bugs you don't ship, the bar you hold in code review. But you'll also be a force multiplier for the entire engineering team, partnering with product, design, QA, and our web engineers to turn complex problems into shipped products.

If you're a strong senior engineer who's also been the person teammates lean on for technical direction, code review, mentorship, and "let me show you how I'd approach that," this role is built for you.

What You'll Do

• Build new experiences that delight customers.
• Own architecture and day-to-day development of our React Native / Expo mobile application.
• Partner closely with our API engineers, not as a downstream consumer, but as a co-author of requirements and contracts.
• Work side-by-side with the web engineering team to ship cohesive, parallel experiences across platforms; coordinate shared patterns, shared concerns, and shared deadlines.
• Collaborate daily with product, design, and QA to translate ambiguous customer problems into clean, shippable solutions.
• Set the technical bar for the mobile codebase through architecture, code review, testing strategy, performance work, accessibility, and release engineering.
• Mentor and uplevel other engineers and act as a force multiplier rather than a single point of throughput.
• Drive technical decisions with a relentless customer focus: what we ship has to work, in the real world, on real devices, for real users.

What We're Looking For

• 10+ years of professional software engineering experience, with substantial recent experience in React Native development.
• Deep, demonstrated expertise with React Native across both iOS and Android, including the practical realities of cross-platform development (platform differences, native modules, performance, app store release processes).
• Hands-on experience using Expo as a development platform - managed workflow, EAS Build / Submit / Update, and the tradeoffs involved.
• Ability to write and maintain native bridges - comfort dropping into Swift/Objective-C and Kotlin/Java when needed.
• A strong customer focus, with a track record of building customer-facing enterprise applications that real people depend on.
• Experience working with an API, helping define requirements, shape contracts, and contribute to implementation decisions.
• Demonstrated technical leadership as a senior IC: setting architectural direction, raising code quality through review and example, and helping less-senior engineers grow through pairing and technical guidance.
• Excellent collaboration skills with cross-functional partners in product, design, QA, and adjacent engineering teams.
• Strong written and verbal communication; comfort operating autonomously in a fully remote environment.

Nice to Have

• Experience integrating with a WordPress backend.
• Experience with user management and subscription / paywall platforms such as Piano.
• Experience with CI/CD pipelines and mobile-specific delivery (TestFlight, Play Console, OTA updates via EAS).
• Experience working with consent management systems.
• Experience shipping in a media, news, or content-heavy product environment.

Why This Role

• Small, focused team — your work and your judgment will be visible from day one.
• Real ownership of a customer-facing mobile codebase, not a slice of someone else's roadmap.
• Cross-functional partnership with product, design, QA, and web teams — fewer silos, more impact.
• Mission-driven work in a media environment that takes its responsibility to readers seriously.

The Straight Arrow Mindset

• Customer-focused - you realize that a great user experience is critical to the success of the company.
• Data-driven - understanding the importance of good data in driving product decisions.
• Collaborative - you brainstorm with fellow engineers to come up with solutions to problems. You work effectively with stakeholders, translating business needs into technical solutions.
• Learning-Oriented: You stay current with best practices and emerging mobile technologies.

Compensation & Benefits

• The salary range for this position is $150,000-$165,000, depending on experience and qualifications.
• SAN offers comprehensive health and wellness coverage that ensures our employees have the care and coverage they need to stay healthy, build current and future financial security and maintain work-life balance. All full-time employees and their dependents are eligible to enroll in our benefits. That includes generous paid time off, paid holidays and floating holidays; health coverage, vision and dental plans; retirement plans like the company's 401(k) plan with company match; and more.

What Impact You’ll Have:

Our team writes CNO software for mobile devices (both Android and iOS) as part of a larger program providing multi-platform support of ongoing operational missions. On some projects in the IC/DoD, you don't see how your work is being used. This project is very different - you get to see the software you write get put into action. You know who is using it, on which missions, and what impact your work is having. You have a ringside seat to the action. The work is very close to the devices and the hardware/software interface. You'll find mobile devices, embedded systems, linux kernels, OS internals, networking, etc. Languages used depend on the specific operational mission being supported and often include, C, C++, Python, and JavaScript. Overall, there is room for a LOT of creativity in how to solve problems. The team is exceptional - both the government staffers and the contractors are highly-skilled, and the team is unusually well-managed. It is fast-paced, with turnaround times being measured in weeks, but without the knee-jerk changes of focus that some projects have. The culture is about doing high-quality work that leads to successful missions: each Engineer's work is visible, so you won't work with any slackers. On-the-job learning is encouraged: as an example, a strong low-level Software Engineer joined the team without much mobile experience, and the team invested time and energy to spin them up on Android and iOS internals so they could become a strong contributor. The team regularly adds CNO Tool Developers, O.S. Internals Developers, Vulnerability Researchers, Reverse Engineers, Mobile Exploitation experts, and Test Engineers with experience developing custom test automation scripts for mobile devices. Work on this program takes place in the Dulles, VA area (we cannot support remote work) and requires a TS clearance, (you can join the project with a TS or higher clearance and over time will be upgraded to TS/SCI + Poly applicable to this customer).

What You’ll Be Owning:

GRVTY is seeking an Android Developer with a TS/SCI + Poly clearance (you can join the project with a TS or higher clearance and over time will be upgraded to TS/SCI + Poly applicable to this customer) to join one of our top projects in Dulles, VA. We are in need of an Android Developer to join our team to solve real-time cyber challenges. Looking for individuals who enjoy working on a mission-focused team that works very closely with our end users. Duties include design custom software tools and techniques for the Android platform; be responsible for end-to-end design and development of custom software; diagnose and debug issues using both COTS and GOTS tools; have a firm understanding of how networks work; develop documentation pertinent to operating and supporting developed software and techniques; mentor and lead junior-level developers to accomplish mission objectives; and solve real-time cyber challenges.

What You Must Have:

• Active TS/SCI with Polygraph Clearance
• Development, testing and debugging Python and C
• Experience in UNIX applications using make files or comparable build environments, mission-applicable platforms.
• Programming CNO tools and techniques
• Network sockets programming and expert packet-level understanding of IP, TCP, and application-level protocols.

• Reverse engineering native binaries.
• Developing proof-of-concept exploit software
• Knowledge of Unix kernel internals, including the OS runtime linker/loader, object file formats (e.g., ELF), file system internals (e.g., NTFS, ext2, btrfs), OS-specific mandatory and discretionary access control mechanisms, and process and thread APIs and data structures
• Understanding of security protection mechanisms (ASLR, DEP, NX), how to defeat them, and how to detect a defeat
• Working with version control software such as git, Gitlab, etc.

What Would Be Nice to Have:

• Experience with native-level mobile development
• Experience with vulnerability analysis
• Experience with assembly, preferably ARM
• Understanding of mobile security protection mechanisms, such as SELinux and application sandboxing Objective-C, Swift or C++ programming
• Ability to work independently and as part of a team in a fast-paced environment with ever-changing requirements.
• Undergraduate degree in Computer Science preferred

Our values are critical pillars to our team culture and shape the way we hire. Read more about what you can expect when working at VSCO on our Careers Page. 

About The Role

If you are passionate about iOS development and excited to join a dynamic team of creators, we encourage you to apply for this position and help us empower creators worldwide. At VSCO, you'll have the opportunity to collaborate with talented individuals who share your passion for innovation and creativity. We're building an ecosystem of end-to-end tools for photographers, enhancing our existing product while creating entirely new tools and services. This is a crucial role for someone who will help define and drive that vision forward, shaping the way our users create, connect and earn. Join us in shaping the future of mobile technology and making a meaningful impact on the global creative community.

As a Staff Engineer, you are first and foremost a technologist. You'll be in the trenches with the team — writing code, solving hard problems, and staying current with the latest technologies. But your impact goes beyond individual contributions. You'll act as a technical leader who guides the team through complex challenges, champions best practices, and anticipates what's coming around the corner so the team can stay ahead. You think about scalability, long-term maintainability, and future features — even while the rest of the team is focused on shipping today's work. You'll mentor engineers, raise the bar on quality, and enable others' success.

In This Role, You Will

• Lead decision making on forward-thinking architectural decisions. Align technical choices with company goals, and be pragmatic enough to choose the faster path when the business demands it. Watch for what is coming down the pike in mobile development.
• Lead by example: write clean, testable, maintainable Swift and Objective-C code. Push for rigorous testing, solid CI practices, and high standards across the codebase.
• Mentor and elevate the team: guide engineers through tricky bugs, design decisions, and architectural trade-offs. Coach, teach, and create space for others to grow.
• Drive code quality through PR reviews, pushing work toward completion in an encouraging way. Your critical feedback motivates authors to improve their work and reach approval.
• Champion AI-assisted development. You’ve used AI tools extensively in your own workflow and actively mentor others to adopt them. You see AI as a multiplier for the team's velocity and quality.
• Architect and implement performant, intuitive solutions for the interactive manipulation of images, video, and mixed media, enabling rich creative expression on mobile devices.
• Contribute to the release process: help manage and improve our release cadence, including feature flagging, release management best practices, and get the process smooth and predictable.
• Collaborate across the organization: work closely with Product, Design, and business stakeholders. Translate complex technical concepts into clear language for non-technical audiences.
• Willing to blur the lines: you are willing to step outside your defined role when the work demands it. Whether it's jumping into an unfamiliar part of the stack or pitching in on cross-platform efforts, you are flexible to help where needed.

Qualifications

• 5+ years of professional experience building iOS applications in Swift and/or Objective-C
• Experience owning projects end-to-end from initial prototypes to customer roll out
• Professional experience working on mobile consumer applications at scale

• Track record of mentoring engineers and raising team-wide code quality
• Experience with feature flagging, release management, and observability tools (Datadog, Crashlytics, etc.)
• Strong cross-functional collaboration skills (you've worked closely with designers, product managers, and business stakeholders)
• Comfort with AI-assisted development workflows and a desire to push what's possibl

Nice to haves

• Experience with React Native
• Experience with OpenGL, 3D rendering, and matrix-based transformations.
• Experience integrating third-party tools for media manipulation.
• Familiarity with Android to facilitate cross-platform design discussions.

Job Perks

• Hybrid work with an office in San Francisco, CA
• Regular in-person events to connect and collaborate
• Competitive salary & equity 
• Medical, dental, and vision insurance for employees and families
