About Company
Started in 2021, Bitstack has evolved from a simple product that invests spare change in Bitcoin into a crypto-native bank bringing a better way to save, spend, and grow money to 300K+ users. Bitstack's mission is to rebuild finance from the ground up — empowering people to achieve financial freedom through a more open and inclusive financial system. Backed by Y Combinator, 13books Capital, Stillmark, and Serena, Bitstack is a small, ambitious team of operators who believe in moving fast, sweating the details, and building products people truly love.
Job Description
As a Senior Software Engineer at Bitstack, your focus goes beyond writing code — you'll own the product from design through to release and beyond. You'll contribute to product decisions, push back on design where needed, and help shape the user experience. Bitstack deploys every day and cares deeply about writing secure, efficient, well-tested software and shipping incrementally. You won't just execute — you'll influence how systems evolve and how the team operates.

- Drive architectural decisions that shape Bitstack's savings and banking platforms.
- Collaborate closely with Product and Design to influence technical direction and trade-offs.
- Ship high-quality, scalable, reliable systems in a production environment.
- Take responsibility for system reliability, security, and long-term maintainability.
- Proactively identify and lead improvements across infrastructure, security, and developer tooling.
- Work in a highly compliant environment and contribute to the broader Bitcoin ecosystem.
- Raise the engineering bar through strong technical judgement and mentorship.
Qualifications
- 5+ years of professional software engineering experience.
- Proven experience owning and delivering complex production systems.
- Strong architectural and distributed systems fundamentals.
- Experience building highly-available and resilient APIs.
- Experience working in cloud-native and microservices environments.
- High ownership mindset and ability to operate autonomously.
- Strong communication skills and comfort working with stakeholders.
- Fluent English (French is a bonus).
- Based in the EU with working rights (sponsorship available in France only).
