The role at Ffern is a sustainable, mission-driven fragrance brand and technology is at the heart of how we grow. We're hiring a Senior Software Engineer to join one of our cross-functional product pods. You'll sit inside a small, focused team of engineers, designers, and growth leads, taking full ownership of revenue-driving customer journeys across acquisition, retention, and lifecycle. Expect fast, iterative work, A/B testing, continuous improvement, and staying close to what you ship. We're a small, ambitious team building something genuinely different in the fragrance world. The work is high impact, the stack is modern, and there's real ownership on offer from day one.
The work
- Take full ownership of at least one core customer journey from architecture through to post-release monitoring.
- Work closely with design and growth to design and implement experiments across acquisition, retention, and lifecycle.
- Constantly improve your area of ownership, both technically and from a growth perspective.
- Support fellow engineers across pods.
Our stack
We run a monorepo architecture managed by Turborepo. Our core technologies include Next.js, PostgreSQL (via Supabase), QStash, Redis, Sanity, Prisma, and Growthbook. We deploy daily and keep our CI/CD lean.
What we need
- 4+ years as a full-stack engineer, ideally with D2C or e-commerce experience.
- You've shipped A/B tests to production.
- You're comfortable with uncertainty and you push hard to get things over the line.
Beyond the technical skills, senior engineers at Ffern are:
- Owners - they take a feature from brief to production without being chased.
- Rigorous testers - they QA their own work and their colleagues'.
- Observant - they add logging, monitor post-release, and use feature flags as standard.
- AI-curious - they actively use AI tools to work faster and smarter.
- Multipliers - they make the engineers around them better.
