Senior Software Engineer – Full‑stack & AI

About the role

We are looking for a Senior Software Engineer to own the full product arc from discovery to production. You will lead client conversations, pressure‑test product decisions before any code is written, and ship predictably within a structured delivery framework for an AI‑native consultancy serving regulated industries.

Key responsibilities

• Lead client‑facing discovery calls, sprint reviews, roadmap discussions and demos.
• Evaluate and pressure‑test product decisions before implementation.
• Scope and deliver work within a structured delivery framework tied to defined business outcomes.
• Build full‑stack applications in TypeScript/JavaScript using Node, React and Next.js.
• Write and maintain BDD test suites with Cucumber and Gherkin.
• Develop daily on the Anthropic API and Claude Code, including structured outputs, tool use and agent workflows.
• Manage client relationships proactively with clear communication and zero surprises.

Required profile

• Fluent English (or equivalent).
• Deep TypeScript/JavaScript experience with production‑grade architecture.
• Strong AWS expertise (Azure/GCP not a substitute).
• Hands‑on experience with LLM APIs (function calling, streaming, structured outputs, prompt engineering).
• Comfortable leading client calls, demos and roadmap discussions with founders and VP‑level stakeholders.
• Ability to context‑switch across multiple client projects and stacks simultaneously.
• Disciplined adherence to structured delivery frameworks, PR hygiene and documentation.
