runna - Senior Software Engineer II (Full-Stack)
Requirements
• We're looking for a talented, high-quality full-stack engineer to join our team. • We care about how well you build software, how you work within a team, and how fast you learn. Runna's stack and problems will keep changing as we grow, so we're looking for strong engineers who pick up new systems quickly and bring good judgement wherever they land, not a checklist match against today's tech. • You'll work closely with your Engineering Manager and a cross-functional squad - product, design and fellow engineers - as well as colleagues across Strava. Wherever you land, the goal is the same: helping Runna become the most trusted training platform for runners everywhere. • We follow a flexible hybrid model that translates to more than half of your time on-site - 3 days per week in Runna's office based in London, UK. • If you don't tick every box below, please apply anyway. Research shows that strong candidates can rule themselves out over a partial match even when they'd do the job well. If you're a strong full-stack engineer keen to learn, we'd rather hear from you than not, and we're happy to talk about whether a different role or level might be a better fit. • You're a strong full-stack engineer (frontend or backend-leaning is fine) with a track record of shipping features end-to-end • You pick up new languages, frameworks and systems quickly, and you're comfortable working outside your current comfort zone as our roadmap evolves • You care about the craft, writing readable and well-tested code, and have good judgement about when to move fast and when to slow down • You enjoy working closely with product, design and other engineers to find the best solution to a problem, not just the most technically interesting one • You take the initiative and look to impact beyond your immediate team, such as improving developer experience or AI-enablement • Our stack today • We hire for general strength, not stack familiarity - most of our engineers joined without prior experience in one or more of the above, and we'll get you fully ramped up during onboarding. • Frontend: React Native, TypeScript, GraphQL • Backend: serverless on AWS, Node.js/Python, DynamoDB, Snowflake • Tooling (continuously re-evaluated): Claude Code, Cursor, Linear with agents, Github with GHA • Experience with native mobile development (Swift, Kotlin, SwiftUI, watchOS) - useful given how close some of our hardest problems sit to the OS, but not a dealbreaker if you don't have it yet • Experience with infrastructure-as-code (Terraform, CDK, CloudFormation) or serverless architectures • Open-source contributions, big or small • A strong interest in health or fitness technology
Responsibilities
• Architect, build, test and deliver features and reliability improvements across the full stack, from our mobile apps through to the systems behind them • Take ownership of problems end-to-end, from design through build, release, testing and support • Work closely with Product and Design to find the most reliable and intuitive solution to the problem in front of you • Help evolve our developer tooling, CI/CD pipeline and engineering standards, and take your turn in the team's release rotation • Be on hand to support teammates on tricky technical problems, wherever they sit in the stack • As you settle in, you'll could dig into things like our recording and sync pipeline, third-party wearable integrations, or interfacing with modelling engineers on plan adaptations - the specifics will evolve with our roadmap and your strengths, so treat this as a flavour of the work rather than a fixed brief
