The Mission 

We’re building GenAI-native experiences that feel inevitable. This isn’t about AI hype — this is about rewriting how product and engineering collaborate to create developer joy, automate friction, and deliver smart, fast, lovable tools. 

You’ll be one of the first few team members on a new internal “strike team” focused on rapid iteration, internal innovation, and product-grade execution. You will prototype fast, fail beautifully, and ship things users want before they know they want them. 

Think of it as: building a startup inside a fintech, but with actual backing, access to production APIs, and direct lines to leadership. 

What Paysafe stands for:

• Being open and honest.
• Keeping focused.
• Operating with Courage.
• Pioneering the future.

Our values and culture are driven by Equality, Development, Social Responsibility and Wellbeing. If you want to find out more about life at Paysafe, check out our careers page here. 

 

How we work:

 

We follow a hybrid working model, spending an average of three days per week at our office location. The office is located in Gresham Street next to St Paul’s cathedral with easy access and transport links via St Paul’s, Bank, Cannon Street, City Thameslink, Liverpool Street, Farringdon, Mansion House.

 

What You’ll Actually Do 

• Build fast. Think Replit-native: zero boilerplate, maximum outcome. 

• Pair with Product to prototype new ideas, test UX patterns, or redesign something broken — often in days, not weeks. 

• Work closely with LLMs, vector DBs, and modern orchestration frameworks (LangChain, LlamaIndex, OpenAI, Claude, etc.). 

• Build user-facing stuff (React, Tailwind, Next.js) and backend flows (Python, FastAPI, etc.) — or whatever tool gets the job done. 

• Design for love, not just function. We don’t do clunky tools. We obsess over magic. 

• Think modularly. Build in a way that lets others build on top of your work. 

• Iterate in public (internally) — demo, test, repeat. 

• Collaborate with one of the sharpest GenAI-native minds in the space (yes, we mean your ecosystem). 

 

You Might Be a Fit If... 

• You’ve shipped products or tools powered by GenAI — not just toy projects, but things people actually use. 

• You’ve used Replit or similar environments and believe coding should be joyful and frictionless. 

• You can work independently but know when to bring others in for the magic. 

• You think in components, flows, and feedback loops — not just code. 

• You’ve played with LangChain, OpenAI, or even built your own agentic workflows. You know where the hype ends and the craft begins. 

• You’re not afraid of ambiguity — in fact, you love shaping the problem. 

• You’ve built or hacked on developer tools, internal platforms, or early-stage AI experiments. 

• You care about UX. You can argue about button spacing if needed. 

 

We’re Not Looking For 

• Resume bullet points. We want builders. 

• AI theory experts who haven’t shipped code. 

• Bureaucrats or "delivery managers." This is a hands-on, high-autonomy role. 

 

Bonus Points 

• You’ve built stuff in the open (GitHub, Replit, Twitter, blogs). 

• You’ve used agents in production, not just demos. 

• You have strong opinions on AI dev workflows — and can back them up with a prototype. 

 

What You’ll Get 

• Autonomy and access — no layers, just results. 

• The chance to define what AI-first product engineering looks like in fintech. 

• Daily exposure to creative, practical GenAI use cases with real-world constraints. 

• A front-row seat to one of the most exciting product transformations in the industry. 

To Apply: 
No cover letter needed. Send a link to something you've built (code, demo, repo, write-up) and a line about what excites you in the GenAI + developer tooling space.
