We're partnering with an ambitious fintech startup that's entering an exciting phase of growth, and they're looking for a Lead Full Stack Engineer to help shape the future of both the technology and the engineering team.

This isn't a role where you'll inherit legacy processes and simply keep the lights on. You'll have the opportunity to influence architecture, mentor engineers, drive engineering best practices, and remain hands-on building products that make a real impact.

Working directly with senior leadership, you'll play a key role in scaling the platform, growing the team, and helping take the business to the next level.

The Role

This is a genuine hands-on leadership position.

You’ll lead a team of three talented software engineers, providing technical guidance, mentoring, and support while remaining heavily involved in software design, architecture, and development.

You’ll help shape the engineering culture, champion clean code and modern development practices, and influence the technical roadmap as the company continues its rapid growth.

If you're someone who enjoys solving complex technical challenges but also loves developing people and driving engineering excellence, this is the opportunity for you.

What You'll Be Doing

• Lead, mentor, and develop a team of three Full Stack Engineers, fostering a collaborative and high-performing engineering culture.
• Remain hands-on across both backend and frontend development, contributing to the design and delivery of new features.
• Design, develop, and maintain scalable backend services using C# and .NET.
• Build modern, responsive, and intuitive user interfaces using Angular, JavaScript, and TypeScript.
• Collaborate closely with Product, UX/UI, and Engineering teams to deliver exceptional user experiences.
• Drive frontend best practices, ensuring applications are performant, accessible, and maintainable.
• Design and implement scalable microservices and RESTful APIs.
• Champion Clean Architecture, SOLID principles, and modern software engineering practices across the team.
• Conduct code reviews, provide technical mentoring, and support engineers with architectural and coding challenges.
• Work closely with senior leadership to influence technical strategy, product direction, and engineering standards.
• Identify opportunities to improve application performance, scalability, security, and reliability across the full technology stack.
• Help shape the engineering roadmap while contributing to the company's continued growth and technical maturity.

What We're Looking For

• Significant commercial experience developing modern .NET applications.
• Strong front-end experience with Angular, JavaScript, and TypeScript.
• Experience designing scalable distributed systems and microservices.
• A passion for writing clean, maintainable, high-quality code.
• Strong understanding of SOLID principles and Clean Architecture.
• Previous experience leading or mentoring software engineers.
• Excellent communication and stakeholder management skills.
• Someone who enjoys being hands-on while helping others grow.
• A collaborative leader who wants to influence technology, architecture, and engineering culture.
