We’re growing extremely fast! In November 2023 we closed a $6.5M funding round led by JamJar with participation from Eka Ventures, Venrex and Creator Ventures. In 2024, we were selected by Apple as one of three global finalists for the iPhone app of the year, reflecting the innovation and impact of what we’ve built & in 2025 we were acquired by [Strava](https://www.strava.com/about?hl=en-GB)! Our ambition is huge: to become the go-to global leading training platform for millions of runners everywhere. We’re growing with purpose and looking for people who want to build something meaningful with lasting impact. With the recent acquisition by Strava accelerating our journey, now is a really magical time to join. 🚀 The team you’ll join We’re looking for a Staff Software Engineer (Full Stack) to play a pivotal role in driving the technical success of Runna. This is a hands-on role where you’ll work across multiple squads, providing architectural direction, ensuring engineering excellence, and enabling the successful delivery of features across the entire Runna platform. We have a jam packed roadmap, with countless opportunities to champion new technologies, work on meaningful problems that impact millions of runners, and improve existing architecture to elevate the whole of our engineering team. 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. ## What you’ll be doing You’ll be a multiplier for the engineering team; mentoring developers, improving processes, and guiding the evolution of our systems as we scale. We’re looking for someone who is not only technically excellent, but also a creative problem solver and collaborative leader who brings energy and clarity to fast-paced environments. - Lead the architectural design and technical strategy across multiple product teams, ensuring scalable, secure, and maintainable solutions. - Champion how we adopt AI across our SDLC, from agentic workflows and automated code review through to the tooling and guardrails that help the wider team ship faster without lowering the bar. - Drive the end-to-end delivery of key initiatives, working hands-on to build, test, and ship features across the full stack (mobile, backend, integrations). - Coach and support engineers by providing technical guidance, mentorship, and code reviews without creating bottlenecks. - Collaborate with Product, Design, and Engineering Leads to define the best solutions for user experience, balancing speed, quality, and long-term technical goals. - Own the release process and support a culture of reliable, continuous deployment—while enabling teams to ship confidently and independently. - Maintain and grow a high-performing engineering culture based on ownership, knowledge-sharing, and continuous improvement. What you’ll bring to the team: - 6+ years of professional experience in software engineering, with a focus on technical leadership and driving projects end-to-end. - Deep expertise in TypeScript/JavaScript, with a strong foundation across the full stack. - Hands-on experience putting AI to work in a real engineering organisation, whether that’s agentic workflows, automated code review, or internal agents. You have a clear view of where it pays off and where it doesn’t. - Familiarity shipping LLM-backed features to production, including prompt and context design, in a user facing product. - Broad AWS experience across serverless (Lambda, API Gateway, AppSync), containers (ECS/EKS) and managed services, with no strong attachment to one deployment model. - Skilled in defining and delivering features from initial architecture and design through to release, testing, and production support. - Able to thrive in a highly skilled, fast-paced engineering team. So far in 2026, we shipped: - 49 mobile app releases (iOS and Android) - 878 API releases - 552 modelling backend releases - Proven ability to mentor engineers, support team growth, and guide complex projects from design to release. - Comfortable with Infrastructure as Code tooling like Terraform, CDK, or CloudFormation. - Able to thrive in autonomous roles, taking ownership without heavy direction. Bonus points if you have: - Experience working with cross-platform frameworks, such as React Native - Have hands-on experience with SwiftUI or native mobile development. - Are confident working with and improving CI/CD pipelines, release cycles, and deployment processes.
