Join Runna, a fast-growing training platform for runners. As a Senior Software Engineer, you'll work closely with cross-functional teams to architect, build, test, and deliver features and reliability improvements across the full stack. You'll take ownership of problems end-to-end and help evolve our developer tooling, CI/CD pipeline, and engineering standards. Enjoy benefits like stock options, paid vacation, and a dedicated hour each week to run.
Missions
- Architect, build, test and deliver features and reliability improvements across the full stack, from mobile apps to backend systems.
- 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.
Profil recherché
- If you don't tick every box below, please apply anyway- You're a strong full-stack engineer (frontend or backend-leaning is fine) with a track record of shipping features end-to-end
- You take the initiative and look to impact beyond your immediate team, such as improving developer experience or AI-enablement
- 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 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
- Tooling (continuously re-evaluated): Claude Code, Cursor, Linear with agents, Github with GHA
- Frontend: React Native, TypeScript, GraphQL
- Backend: serverless on AWS, Node.js/Python, DynamoDB, Snowflake
- 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
- 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
- A strong interest in health or fitness technology
- Open-source contributions, big or small
