Engineering Lead

What makes this role special

• You are joining a small, senior team where your decisions shape the architecture, not just a ticket in a backlog
• Direct collaboration with the CTO & Co-Founder from day one
• High ownership: you ship, you learn, you improve
• Your work has immediate, visible impact on a product used by SME founders who rely on Integral for their financial operations
• The engineering culture is yours to help define.

YOUR PROFILE

Your Experience & Mindset

• 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
• Focused execution: you thrive in a hands-on role and are energised by practical outcomes, not by building a team around you.

Preferred Experience

• Experience building in regulated or compliance-heavy domains
• Familiarity with German accounting, payroll, or tax systems is a plus but not required
• Experience integrating LLMs or AI capabilities into production systems.
