Warsaw, Poland

INGENIOUS.BUILD is seeking a skilled Developer Team Lead who is passionate about writing code and excited to lead a small team of engineers. This person should embrace Servant Leadership and be passionate about empowering their team to grow and succeed. The Developer Team Lead should also have excellent programming skills and a deep passion for developing large applications.

At INGENIOUS.BUILD Our goal is to minimize meetings so that you can focus on what you do best: building. We understand the importance of flexibility, which is why we offer flexible working hours that allow you to work when you’re most productive. We aim to  foster a collaborative environment that avoids unnecessary bureaucracy, enabling every team member to influence the product. Our team and culture are built around experienced individuals who enjoy discussing interesting challenges and sharing knowledge, ensuring there is always support and inspiration readily available. We encourage asking questions, challenging assumptions, and collaborating across functions to achieve successful outcomes. 


Being a part of the team you will: 

  • Use software like PHP 8.4, Laravel 11 and PostgreSQL.

  • Lead and guide one engineering team to plan, build, and deliver high-quality software while optimizing code, managing resources, and ensuring timely delivery.

  • Oversee hiring, onboarding, and performance reviews, contributing to team and company growth.

  • See that our goal is to minimize meetings, allowing you to focus on what you do best: building.

  • Our flexible working hours mean you can work when you’re most productive.

  • This is a collaborative space and avoids unnecessary bureaucracy, so every team member influences the product.

  • Our team has many experienced people who love discussing interesting challenges and sharing knowledge, so there’s always support and inspiration around every corner.

  • Be committed to continually improving our codebase, reducing legacy code, adding tests, and keeping things up-to-date.

  • The DevOps team is responsible for infrastructure, so you can focus on development. Our pipelines are set up with PHPStan, PHPCS, unit, integration, and end-to-end tests, all supporting automatic deployments.

  • Learn that our philosophy is to write code that’s easy to test and reason about. By structuring business logic in clear PHP classes, separate from the framework, we avoid complex, 'magical' solutions that complicate understanding and testing.

  • We have a fairly big modular monolith. The interactions between modules are based on facades, adapters, or events, helping us maintain strong boundaries and modularity. In our more intricate modules, we incorporate DDD to keep the domain logic well-structured and business-aligned.


What type of person are we looking for?

  • We’re looking for engineers who care about impact, not just implementation. You won’t just take tickets and ship code, you’ll help shape the solution. 

  • We value teammates who think beyond their “part,” who want to understand the why behind the work, and collaborate to find the best path forward.

  • Someone proactive who brings fresh ideas and energy to the team

  • A developer with grit and a drive to tackle tough challenges

  • A person excited to be part of a transformative project that could reshape the industry


Skills and Experience needed or preferred:

  • Communicative English at a B2 level or higher.

  • Extensive experience building scalable applications, ideally with large-scale systems like CRM, CMS, or ERP. Direct SaaS experience is a strong plus.

  • Advanced proficiency in PHP 8.1+ and modern frameworks like Laravel or Symfony, with experience in modular monolith and layered architecture.

  • Strong focus on framework-agnostic development, prioritizing clean, maintainable code that maximizes business value and minimizes dependencies.

  • Thorough knowledge of automated testing frameworks (e.g., PHPUnit) and robust testing strategies, ensuring high-quality, reliable, and maintainable code.

  • Experience managing a team of developers and being responsible for delivering multiple complex projects.


Benefits of Working with Us:

  • We provide high-performance company laptops for optimal productivity.

  • Unlimited PTO lets you take the time you need to recharge.

  • One-time $500 office budget to set up your workspace.

  • $50 monthly for educational resources, rolling over until year-end.

  • Licenses for tools like GitHub Copilot, Claude Code and PhpStorm.

  • Stock options so you can share in the company’s growth.

You'll own features end-to-end — from pixel-perfect frontend work to shipping backend functionality when needed. This is not a siloed role. You'll move fast, make real decisions, and have direct impact on a product used by people who care deeply about learning and research. We don't have managers. We have engineers who own their work. TECH STACK The stack is heavily TypeScript. On the frontend: SvelteKit, Tailwind, DaisyUI, and Playwright, with DDD and CQRS patterns. On the backend: Node.js, Fastify, PostgreSQL, and queues. ML components are in Python. The stack is pragmatic, not dogmatic — tools may shift as the product evolves. WHAT WE LOOK FOR Elite communication You set accurate expectations and live up to them. No surprises, no ambiguity about status or blockers. Deep resilience Bugs, crises, tough reviews — you have a large buffer before stress impacts your output. You don't crack under pressure. No ego We're here to build something great, not to manage insecurities. The best idea wins, regardless of who had it. Product mastery You understand the engineering principles behind the best software ever made — and care deeply about the difference between good and great. Independent and obsessive by nature You go deep on everything you touch. You're a lifelong learner who can't help but care about quality. Being an ex-founder is a bonus. ENGINEERING CULTURE Optional code reviews We trust you. Merge when you're ready. Ask for a second pair of eyes when you want one. Radical autonomy We don't second-guess your decisions. You own the call. High-bandwidth collaboration Constant communication means everyone has context without formal gates or status meetings. Direct feedback Code reviews are blunt, concise, and respectful. We say what we mean. Ruthless efficiency We aggressively adopt any tool — AI included — that increases speed and leverage. Limited frontend test coverage Supplemented by strong architecture and top talent, not bureaucratic QA processes. RECRUITMENT PROCESS Recruiter screening — a short intro call to align on basics. 1-on-1 with the engineering lead — a conversation about how you think and work. Technical challenge (~4 hours) — use AI, Google, or any resource you need. We care about the result, not the method. One-month paid contract — with the possibility to extend indefinitely. Honest, frequent feedback throughout so you always know where you stand. COMPENSATION & BENEFITS Salary $100,000 – $150,000 depending on experience. Equity and profit share Core team members receive both equity and profit share as part of the compensation package. Unlimited PTO Use your own judgement — we won't count days. Steep learning curve You'll grow faster here than almost anywhere else — by design, not accident. Real ownership No managers capping your authority. You own your work end-to-end, with the full trust of the team behind you.
