Engineering Lead

About the role

As Engineering Lead, you will help define the tech stack and shape engineering culture at Integral. This role involves frequent context switching across multiple domains, technologies, and business problems—moving between infrastructure, backend systems, integrations, AI initiatives, frontend work, and product collaboration. You will work alongside experienced engineers in a small, high-impact team building accounting, payroll, and tax solutions for SMEs across Germany.

What you'll do

• Design, develop, and deploy across the entire technology stack: from backend services and infrastructure to frontend development; build, test, and ship solutions based on evolving business requirements without sacrificing quality
• Take end-to-end ownership of architectural decisions from initial design through to implementation; collaborate with the senior team to refine solutions and ensure they meet real business objectives
• Maintain detailed documentation of technical decisions, processes, and system architecture; foster transparency and continuity by sharing insights clearly and consistently across the team
• Work directly with the founding engineering team on the core platform that powers Integral's accounting, payroll, and tax services for thousands of SMEs across Germany

What you'll need

• 8 to 10+ years of professional experience in software engineering with a strong track record of building and shipping in startup or scaleup environments
• Experience across multiple companies and environments; you have seen different architecture patterns, made the mistakes, and know what actually works
• Staff, Principal, or Senior Engineer background where building and owning was the main focus, not coordinating or managing
• Proficiency across a broad technical background with a strong foundation in system design and architecture
• Strong command of at least two of the following: Java/Kotlin, JavaScript/TypeScript, React/React Native, Python
• Expertise in architectural decision-making: you can design systems that balance complexity with long-term maintainability
• Autonomous and pragmatic: you frame problems independently, design solutions, and execute without needing extensive support from other teams
• Strong written communication: you write detailed technical documentation and decision rationale as a default, not an afterthought

Nice to have

• Experience building in regulated or compliance-heavy domains
• Familiarity with German accounting, payroll, or tax systems
• Experience integrating LLMs or AI capabilities into production systems

What they offer

• Above-market salary
• 28 vacation days per year with December 24th and 31st each counting as half days
• Urban Sports Club membership or Deutschland Ticket
• Company pension plan and fully stocked modern office in Berlin Prenzlauer Berg
• Weekly team lunches, office BBQs, and dinner budget for late nights
• Laptop of your choice: MacBook or Windows Pro
