Our client is a technology startup founded by engineers with 25 years of combined experience delivering everything from hypercars to buses. Their vision is bold: to automate the development of control software.Unlike others, they do not rely on third-party LLMs. Instead, they have developed their own foundation model entirely from scratch, using novel technology. This is not about automating code snippets or creating an assistant — it is about building a standalone engineer.

What we are looking for:

Soft Skills:

• Hard-working mindset: delivery above all else!
• Curiosity-driven: eager to understand systems at a fundamental level, always willing to peek under the hood
• Architectural thinking: ability to see the whole system and design end-to-end
• Smart, resilient, detail-oriented, and super fast

Hard skills:

• 5+ years of professional software development experience
• Strong back-end expertise in one or more of the following: Node.js, C++, Python
• Production-level proficiency with React
• Strong understanding of cloud platforms (e.g., AWS, Azure)
• Familiarity with database design and management (SQL, NoSQL)
• Ability to design and build large-scale SaaS architectures from scratch

What you will do:

• Architect, design, and develop a full-stack solution around the client’s core technology
• Build a product for engineers: robust, scalable, and performant
• Integrate with third-party toolchains and cloud-based clusters
• Optimize the system for performance, scalability, and security

Benefits:

• Competitive compensation + share options
• Total freedom in technology stack. Select a setup that makes the product (and you) efficient
• Brutal honesty and extremely transparency — no management jargon, only the simple truth
• Relocation package and visa sponsorship
• 28 vacation days + UK public holidays
• Modern hardware equipment
• Gym membership in London
