Senior Recruitment Consultant @ SR2 B Corp™ | LLB | Headhunting Python Engineers🐍 | Helping Tech4Good Businesses Build Impactful Products | Advocate…

Location: London (hybrid)

Salary: Up to £100,000 (+/- 10% DOE) + equity

• Python ecosystem - experience with Django, or Flask, or FastAPI
• TypeScript & React across the frontend - any frontend experience beneficial
• Cloud native environment

This is not a “slot into an existing team” role.

This is a build it, shape it, own it role.

We are partnered with a mission driven technology company tackling complex, real world problems through software. The product is live, the ambition is big, and the next stage of growth depends on getting the technical foundations right. That is where you come in.

They are looking for a Founding Engineer who wants responsibility, pace, and influence. Someone who is comfortable making decisions, writing production grade Python, and working across the stack to ship meaningful features quickly.

If you are energised by early stage environments, imperfect information, and the chance to build technology that genuinely matters, read on.

The role

• Join as a founding member of the engineering function with real ownership from day one
• Design and build core backend services and APIs using Python
• Work end to end across the stack to deliver clean, intuitive user experiences
• Make pragmatic architecture decisions that balance speed, scale, and long term health
• Work closely with product and design to turn ideas into working software fast
• Set technical direction, standards, and ways of working as the team grows

What they are looking for

• Strong commercial experience building production systems in Python
• Confidence working across backend and frontend when needed
• Experience in fast paced startup or scale up environments
• Comfort operating with ambiguity and making decisions without perfect information
• A bias toward action, ownership, and outcomes
• Clear communicator who collaborates well in a hybrid setup
• Genuine motivation to work on purpose led technology with positive impact

The kind of person who thrives here

You care about what you build and why it exists. You enjoy momentum. You are not waiting to be told what to do. You see problems, take ownership, and move.

You want your work to matter, not just function. You are excited by responsibility rather than intimidated by it. You would rather help shape a product and a team than inherit someone else’s decisions.

This is a chance to be early, to be heard, and to build something that aligns with your values as well as your technical ambition.

• Hybrid working in London
• Salary up to £100,000 with flexibility
• Meaningful equity
• The chance to play a genuine founding role in a Tech4Good business
