This is an opportunity for an engineer who enjoys taking ideas from concept → code → production, thrives without a huge amount of process and wants to work on AI applications that solve genuine business problems.

- Work across frontend and backend systems.
- Integrate modern AI capabilities into customer-facing products.
- Build reliable workflows around LLMs, agents and automation.
- Take ownership of projects from initial concept through to production.
- Make pragmatic architectural and technical decisions.
- Work closely with product and business stakeholders to turn problems into simple solutions.
- Learn from customers and continuously improve what you build.
- Help establish strong engineering practices as the team grows.
What I'm looking for...
- Strong commercial experience with JavaScript / TypeScript.
- Solid frontend and backend development experience.
- Experience building and shipping AI-powered functionality in production.
- Understanding of LLM workflows, tool calling, agents or orchestration.
- The ability to operate effectively with incomplete requirements.
- Strong product instincts and an interest in understanding why something should be built.
- Excellent communication skills.
- A pragmatic approach to engineering knowing when to move quickly and when to go deeper.
Bonus points for...
- Experience building agentic systems or multi-step AI workflows.
- Experience with evaluation, memory or orchestration approaches.
- Previous experience in an early-stage or rapidly scaling company.
- Mentoring other engineers or taking technical ownership of projects.
- A genuine curiosity about what AI can make possible.
