Full-Stack Product Engineer – Shipping the Future of AI in Finance - Remote (if preferred)

? Location: Office in London; open to remote with occasional travel.

? Type: Full-time

? Reach: Trusted by 40% of the world’s top 50 financial firms

We’re building AI agents to solve the hardest knowledge problems in finance.

We’ve recently been named one of the Top 25 FinTech AI Companies of 2025 by The Financial Technology Report, just days after landing on CB Insights' AI 100 list for 2025. We’re also backed by some of the best investors in the world, including Sequoia and Neotribe Ventures.

Our mission is simple: eliminate the hours financial professionals waste on repetitive, manual analysis—so they can focus on what really matters. We're building advanced, domain-specific AI systems that automate deep, complex reasoning in financial workflows. Think of it as an intelligence layer that does the reading, interpreting, and answering—across thousands of unstructured data sources—on behalf of our users.

We’ve been growing fast: 5x revenue growth year-on-year, with the same trajectory forecasted for 2025. Our platform is already trusted by nearly half of the top 50 financial institutions globally.

? The Technology

At the core of our platform is a RAG-based architecture, purpose-built for finance. It’s designed to replicate the kind of deep reasoning you see in leading models like OpenAI’s o1—capable of parsing nuanced questions, retrieving domain-relevant knowledge, and producing context-aware answers with minimal hallucination.

You’ll work with state-of-the-art AI stacks, combining LLMs, vector search, and custom orchestration to automate tasks that have traditionally taken analysts days or even weeks.

? What You’ll Do

As a Product Engineer, you’ll be embedded deeply within one of our most strategic client engagements—delivering real value through hands-on development and technical leadership.

You'll:

• Design and build full-stack features (Python, React) that solve high-value, knowledge-intensive challenges in finance
• Work autonomously across the entire product lifecycle—from discovery to delivery
• Act as a mini-CTO for the customer—owning solution architecture, technical delivery, and continuous improvement
• Collaborate closely with AI researchers, designers, and product leads to bring groundbreaking user experiences to life
• Translate business pain points into technical strategies that scale across users and use cases
• Shape product direction through direct feedback from high-stakes, real-world usage

? You Might Be a Fit If You…

• Have 4+ years of experience as a software or product engineer, ideally in fast-paced, early-stage environments
• Are proficient with modern web frameworks (Python, React, TypeScript, etc.) and can build production-ready systems end-to-end
• Are excited by AI-native product design and have experience working with or around LLMs, RAG, or agent-like architectures
• Love talking to users and solving real business problems—not just coding in a vacuum
• Bring an entrepreneurial mindset, with an eye toward growing into a CTO, founding engineer, or VP-level role
• Thrive on ownership, autonomy, and delivering software that actually matters

Why This Role Is Different

• Real-world AI, not hype – Work on production-grade, high-impact systems used by world-class institutions
• Accelerated growth – Join a company that’s 5x’d revenue for two straight years and isn’t slowing down
• Customer intimacy – Sit at the intersection of product and strategy, not buried in a feature factory
• Elite talent, low ego – A small, globally distributed team that’s fast, curious, and deeply collaborative
• Long-term opportunity – Help define a new product category in AI and carve out your leadership path as we scale

If you’re excited about building deeply technical, AI-driven products that solve real-world problems—and want to work directly with global financial leaders—this is your moment.

No hoops. No rigid requirements. Just reach out and show us what excites you about this space.
