Founding Deployed Engineer in London

Location: London

Employment Type: Full time

Location Type: On-site

Department: Office of the CEO

About Delfa: Billions of people still suffer from everyday diseases. One key reason? Clinical trials are broken. Despite $120 billion spent each year, most trials are delayed due to bottlenecks like patient recruitment. Delfa is fixing this with autonomous AI agents. We're building AI agents to automate clinical trials. In less than a year from launch we've already:

• Deployed onto 300+ trials across multiple conditions
• Reached seven figures in ARR, growing 22% MoM
• Raised an oversubscribed $3.8m seed from tier-one AI investors

Overview: Delfa is at a critical inflection: we have a proven offering which is on track to support the recruitment of thousands of participants into trials in 2026, while simultaneously expanding our offerings with new products for biopharmaceutical companies. We are hiring a Founding Deployed Engineer to own the conversion of pilots, success of new customers and identification of new product opportunities. You will be responsible for deeply understanding our customer needs and working shoulder-to-shoulder to solve them.

What You'll Do:

• Own the pilot-to-customer conversion process end-to-end, from onboarding, value quantification through to expansion
• Build scalable onboarding processes and playbooks that can work across a growing customer base
• Deploy AI agents to handle onboarding grunt work and free up time for high-leverage customer interactions
• Work directly with customers to extract validated product insights and quickly prototype solutions to test them
• Spot patterns across the customer base and package them up for engineering so the right things get built
• Help open and grow our US presence as we expand our commercial team there

You'll Be A Great Fit If…:

• You are technical and commercial in equal measure: You're comfortable writing code to prototype a solution and equally comfortable sitting in front of a customer explaining why it matters. The bridge between those two worlds is where you live.
• You are obsessed with feedback loops: You understand that in a world where code is cheap, the real bottleneck is extracting validated ideas from customers fast. You build systems and habits to make that happen.
• You thrive in complexity: Clinical trial sites are regulated, risk-averse organisations with high stakes. You know how to build trust with them and how to show them value in a way that meets them where they are.
• You don't wait for instruction: You identify the problem, define the solution, and move. When you see a pattern across three customers, you've already written the proposal before anyone asks you.
• You love using AI: You reach for Claude, Cursor, or whatever the right tool is to ship faster. You're experimenting constantly and sharing what you learn.

Life at Delfa: Delfa is building a generational company to transform the way medications reach millions of patients in need. This is your opportunity to get in on the ground floor and work alongside the highest talent density team in the space, onsite at our London office 5 days a week:

• A wine-snob who built foundation models at Roche at ETH Zürich
• A former hedge fund trader with world class causal AI knowledge
• A medical doctor turned AI engineer who builds prototypes on the weekend for fun
• A ginger bloke who deployed production AI for J & J, Medtronic, and Exscientia

What We Offer:

• Competitive salary + meaningful equity
• Private health insurance and gym membership
• 25 days' holiday + UK public holidays
• Modern office space 5 mins from Old Street station
• True 0-1 ownership.

Our Hiring Process: We work to get you an offer within a week with a lean process:

• Intro chat with Tom (CEO) - 30 mins: A discussion about your experience, values, and career goals, and an opportunity to get a sense of the role and the team. After this call we may ask you to share some work you're proud of.
• Deeper dive with Gustav (Co-founder) - 30 mins: A deeper dive into how you approach complex customer and product problems, and the chance to understand more about what we're building.
• Challenge - 90 mins: We'll invite you to our office and give you a real customer scenario to work through with us. It's the best opportunity for you to truly see if this is the right role for you — and for us to see how you'd collaborate.
