Randstad Technologies is acting as an Employment Business in relation to this vacancy.

Morela is supporting a fast-growing AI start-up in hiring multiple Forward Deployed Engineers to work directly with customers, embedding into their environments to design, build and deploy high-impact AI solutions.

This is not a Back Office engineering role. You will be on the front line, translating ambiguous business problems into working AI systems, often under real-world constraints and with limited runway for iteration.

If you are more comfortable shipping solutions with clients than sitting behind internal tickets, this is for you.

WHAT YOU’LL BE DOING

• Work directly with clients to understand their business challenges and translate them into scalable, working technical solutions
• Design and deploy AI and ML systems in production customer environments
• Rapidly prototype, iterate and refine solutions based on real user feedback in Real Time

• Pragmatic builder, focused on delivering value, not over-engineering
• Confident enough to push back on clients when needed and guide them toward the right solution
• Thrives in high-impact, high-visibility environments where the work matters

REALITY CHECK

This role is not for someone who needs tightly defined requirements before they can start. It is not for someone who prefers purely internal engineering work, or who lacks confidence in a client-facing environment.

WORKING SETUP

• London-based with 2-3 days per week on-site with clients
• Remaining time remote
• Outside IR35 - £750 per day
• Multiple openings - contract length to be confirmed
