The Opportunity
Our client is an ambitious, well-funded technology company building AI-powered solutions that are transforming accounting, taxation and payroll for SMEs across Europe.
As an Engineering Lead, you'll play a key role in shaping the technology and engineering culture from the ground up. This is a highly hands‑on role where you'll move across different areas of the stack, solving problems across infrastructure, backend, integrations, AI and frontend.
You'll work closely with the founding engineering team, taking ownership from problem definition through to production, while helping shape the architecture and technical direction of the platform.
This is a fully onsite role based in Berlin, working closely with the CTO, founders and senior engineering team.
What You'll Do
- Design, build and deploy solutions across the full technology stack
- Work across backend services, infrastructure, integrations, AI and frontend development
- Take end‑to‑end ownership of architectural decisions, from initial design through to implementation
- Translate evolving business requirements into scalable, maintainable technical solutions
- Work closely with senior engineers to evaluate and refine technical approaches
- Document architectural decisions, technical processes and system design
- Collaborate directly with the founding engineering team on the core platform
- Move comfortably between different technical and business problems as priorities evolve
- Take ownership of systems in production, including ongoing improvement and support
- Help shape engineering standards, practices and culture as the team grows
What Makes the Role Interesting
- True technical ownership: Your decisions directly influence the architecture rather than simply contributing to a backlog
- Broad technical exposure: Move between infrastructure, backend, AI, integrations and frontend
- Direct founder access: Work closely with the CTO and founding engineering team
- Small, senior team: Collaborate with experienced engineers who care about quality and craftsmanship
- Immediate impact: Build technology supporting the financial operations of thousands of SMEs
- Shape the culture: Help define how the engineering team builds, ships and learns
- AI‑native environment: Work with modern AI development tools and production AI systems
Your Experience
We're looking for someone with:
- 8–10+ years of professional software engineering experience
- A strong track record of building and shipping products within startups or scale-ups
- A background as a Senior, Staff or Principal Engineer, where hands‑on engineering and ownership were central
- Strong experience with system design and software architecture
- Strong proficiency in at least two of:
- React / React Native
- Python
- Experience making architectural decisions that balance complexity, scalability and long‑term maintainability
- The ability to work autonomously and take problems from definition through to execution
- Strong written communication and a habit of documenting technical decisions
- A pragmatic, hands‑on approach focused on shipping and measurable outcomes
- The ability to comfortably switch between different technical domains and priorities
Particularly Relevant Experience
- Experience building products in regulated or compliance‑heavy environments
- Experience with accounting, payroll, tax or other financial systems
- Experience integrating LLMs or AI capabilities into production systems
- Experience working across multiple startups or scale‑ups and exposure to different architectural environments
- German accounting, payroll or tax knowledge would be a plus
