Job description

Lead Full Stack Engineer

Consortia are partnering with a high growth climate tech scale up that is digitising and modernising the energy ecosystem.

They are hiring a Lead Full Stack Engineer who is as comfortable writing production grade code as they are line managing and developing engineers. If you are looking for a role where you can both build and lead, while contributing to the clean energy transition, this is a pivotal hire as the team scales.

The business is expanding its engineering capability and now needs someone who can raise the technical bar while taking genuine ownership of people leadership. In the early months, you are likely to be deeply embedded in the codebase, building context and credibility through delivery. As the team grows, your leadership scope will expand and you will become a key multiplier, helping remove scaling constraints and shape the evolution of the engineering function.

You will take ownership of architecture and technical direction across core systems, ensuring the platform scales intelligently. You will remain hands on, writing high impact production code and designing solutions that connect multiple parts of the product. Alongside this, you will provide structured line management, supporting career progression, leading performance conversations, and mentoring engineers into greater responsibility. This is a true hybrid role that combines technical depth with meaningful people leadership.

The technology stack is pragmatic and focused on solving real world problems. It includes

Node.js, TypeScript and React, with PostgreSQL and PostGIS supporting data intensive requirements. Prisma, Docker andTailwind.

You do not need experience with every tool, but you must have strong full stack fundamentals, a solid product engineering mindset and the confidence to own problems end to end.

You will bring strong JavaScript / TypeScript experience across frontend and backend development, alongside a clear understanding of API design and relational databases. You have mentored engineers and may already have line management experience, conducting development and performance conversations with maturity and clarity. You are comfortable operating in ambiguity, focused on outcomes rather than output, and balanced in your approach to quality and pace.

Most importantly, you genuinely want to manage people. Not simply coordinate tasks, but develop individuals, raise standards, and build a healthy engineering culture.
