What they need


  • As a Senior Developer, Fullstack (AI & Data Platform), you will join a highly motivated and experienced team building agent-enabled applications and backend automation that turn catalogue and metadata into governed, production-quality software

  • Working alongside data engineering and governance partners, you will design services, tooling, and user-facing interfaces that make data discoverable, trustworthy, and easy to consume across the platform. We are looking for people who can bring a strong, consulting and solution-focused mindset and contribute to architectural decisions, best practices and get things done

  • Develop backend automation that integrates multiple metadata sources and generates governed artifacts - for example, automatically producing a data contract for review, editing, and publication to the registry

  • Design and build agent-enabled applications and workflows, including MCP servers and tools such as a data-contract generator or a data-readiness assessment utility

  • Build user-facing interfaces for platform and discovery workflows

  • Deliver production-quality services with sound API design, testing, and CI/CD practices

  • Experience with unit testing, integration testing, and modern DevOps practices (e.g., Git, CI/CD pipelines)

  • Proficiency in modern frontend frameworks, specifically React and Vue.js, as well as ES6 and TypeScript

  • Experience designing, developing, and consuming RESTful APIs and microservices

  • Bachelor’s Degree in Computer Science, or equivalent

  • Experience with Neo4j, Supabase

  • Understanding of Graph RAG data structures

  • Software engineers who understand data-engineering principles and can transform catalogue and metadata output into working software

  • Proven track record in architecting agentic workflows and AI-driven solutions, incorporating deep integration with LLMs and sophisticated autonomous frameworks

  • Strong understanding of agile principles and methodologies

  • Strong Python engineering skills, including API and service design (e.g., FastAPI), asynchronous programming, and schema validation (Pydantic / JSON Schema)

  • Experience developing and optimizing code using AI-powered tools such as Claude Code and GitHub Copilot to enhance productivity and code quality

  • 6+ years of experience in software engineering with a strong focus on fullstack development

  • Experience with Cloud Computing and Serverless Architecture, preferably AWS

  • Governance and catalogue: Collibra, Unity Catalogue, Horizon; YAML data contracts

  • Frontend: React, TypeScript, Next.js; Supabase (interfaces align with the platform’s established internal tooling)

  • Infrastructure and data: Docker, AWS, PostgreSQL, Databricks, Snowflake, Supabase

  • AI and agents: MCP (build and consume), large language model and agent frameworks, Snowflake Cortex and Genie, Neo4j

  • Backend (primary): Python - FastAPI, Pydantic, asynchronous services

  • Prior experience and connections in the Life Sciences industry is preferred

  • You think about how to scale, automate and operate, not just how to build a solution to an immediate problem

  • You have a customer-first mindset and a devotion to customer service

  • You have solid analytical, problem-solving, and decision-making skills

  • You understand lean thinking

  • You set high standards for code quality, performance/scalability and security and seek continuous improvement

  • You have prior experience in consulting

  • You have strong self-initiative, passion, interpersonal, oral and written communication and collaboration skills with the ability to work, influence and make an impact in a cross-functional environment with all levels of the organization

  • You engage and build positive internal and external client relationships, while managing multiple initiatives, often with competing priorities

  • You are responsive and thrive in a fast-paced diverse high-performance environment with rapidly changing business needs

  • You actively seek out things outside your comfort zone with the ability to rapidly learn and take advantage of new concepts, business models, and technologies

  • Familiarity with data governance and catalogue tooling and with data-contract standards

  • Experience building MCP servers in addition to consuming them

  • Experience in a regulated or life-sciences environment
