The team you’ll join
We’re looking for a talented, curious and experimentation minded Senior Full Stack Engineer to join Growth Engineering team.
This team owns key parts of the user journey into Runna, working across web and app to create high quality experiences that turn first time visitors into longterm, engaged subscribers.
You’ll collaborate closely with product, design and data partners, as well as our founders and CTO, to shape how new users first discover and experience Runna.
- What you’ll be doing
- Architect, build, test and ship high impact user journeys and subscription funnels, taking technical ownership across multiple workstreams and setting the standard for how the team approaches conversion engineering.
- Lead the technical strategy for experimentation across web and app — defining how we run, instrument and learn from experiments at scale, not just executing individual tests.
- Work closely with Product, Design and Data to shape the roadmap, proactively identifying opportunities across teams and ensuring our technical investments balance long term scalability with shorter term business goals.
- Identify and align with other engineering and product teams whose work intersects with Growth, driving cross-team coordination to deliver consistent, high-quality user experiences across the platform.
- Own and evolve the instrumentation, tracking and tooling strategy for the team — establishing standards for how we measure behaviour and impact, and guiding other engineers in applying them.
- Own features end‑to‑end and drive the technical direction of larger, multi-milestone projects — coordinating across engineers, managing sequencing and dependencies, and communicating risk to cross-functional stakeholders.
- Elevate our engineering culture by improving CI/CD, testing and release workflows, and establishing coding standards and best practices that raise the bar for the whole team.
What you’ll bring to the team
- Strong Type Script/Java Script experience, with a track record of establishing patterns and standards that other engineers adopt.
- Experience building user-facing product surfaces where conversion and UX really matter, and an ability to shape the technical direction of those surfaces — not just deliver features within them.
- Comfortable leading in a fast-paced, iterative environment — setting the technical vision for how the team experiments and learns, and helping others do the same.
- 3+ years experience, with depth in at least one area of the stack and the range to contribute meaningfully across it.
- Skilled at delivering large, complex projects end‑to‑end: from architecture and technical design through phased rollout, measurement and iteration — with the ability to coordinate multiple engineers across stages.
- You think deeply about what didn't work and why, and translate those learnings into better processes, frameworks or tooling for the team.
- Enthusiasm for — and ability to actively shape — our ways of working:
- Iterative development, continuous deployment and test automation.
- Knowledge sharing, pair programming and collaborative design.
- Shared ownership of code and outcomes across cross‑functional teams.
- Experience working full-stack, with a willingness to guide and mentor others across the stack as needed.
