AI Data Scientist
About ComplyFirst
Complyfirst is a reporting automation platform for financial services compliance teams. We remove 80% of manual reporting work so teams can focus on reviewing, not doing. We grew almost 6x last year and are hiring across the business.
Role Overview
We’re hiring an AI Data Scientist to work directly with our CTO and engineering team. Your job is to design, build, and ship AI and ML models that make our compliance product meaningfully smarter - from automating document interpretation to improving how we detect and flag suspicious activity.
This is a hands-on role. You’re not here to research. You’re here to build things that work in production and make a measurable difference to what our clients can do.
What You’ll Do
- Build and ship AI/ML models. Design, train, and deploy models that power core product features - from document parsing and classification to anomaly detection and narrative generation.
- Own the full model lifecycle. From problem definition through to production. You’re responsible for what you build, including monitoring, iteration, and improvement after it ships.
- Work directly with engineering. Collaborate closely with the dev team to integrate models into the product cleanly. You understand how your work fits into a production system.
- Push our AI roadmap forward. Work with the CTO to identify where AI can have the biggest impact on the product and build the case for what we build next.
- Stay ahead of the field. The AI landscape moves fast. You track what matters, cut through the noise, and apply what’s genuinely useful.
What We’re Looking For
- Real world experience building and deploying AI/ML models in a production environment — not just research or experimentation.
- Strong Python skills. You’re comfortable with the modern ML stack: PyTorch or TensorFlow, LangChain or similar, and the tooling around it.
- Experience with LLMs. You’ve worked with large language models in a product context — fine-tuning, RAG, prompt engineering, or building pipelines around them.
- High agency. You define the problem, propose the approach, and execute. You don’t need the work handed to you.
- Commercial instinct. You care about whether your work actually moves the product forward, not just whether the model performs well in evaluation.
- Clear communicator. You can explain what you’re building and why to non-technical stakeholders without losing the detail that matters.
This Role Is Not For You If…
- You’ve worked primarily in research or academic settings and haven’t shipped models into production.
- You need a large data team around you to get things done.
- You’re looking for a clearly scoped role with well-defined problems. We’re still figuring out a lot of this.
- You’re not comfortable working in a fast-moving, early-stage environment.
What We Offer
- Competitive salary, based on experience
- Private medical cover
- Hybrid or fully remote roles available
- 35 days holiday (inclusive of bank holidays)
- Company laptop
- Outsized responsibility and growth, from day one
