About us

Appnovation is a global, full-service digital partner that combines Strategy, Experience & Design, Engineering and Managed Services. We build digital solutions that deliver real impact today and serve as foundations for future growth. Bold ambition. Practical action. Endless possibilities.

ABOUT THE ROLE

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.

WHAT YOU WILL DO

• 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.

QUALIFICATIONS

• Bachelor's Degree in Computer Science, or equivalent.


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


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


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


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


• Understanding of Graph RAG data structures.


• Experience with Neo4j, Supabase.


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


• 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.


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


• Experience with Cloud Computing and Serverless Architecture, preferably AWS.


• Strong understanding of agile principles and methodologies.

PREFERRED QUALIFICATIONS

• Experience building MCP servers in addition to consuming them.


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


• Experience in a regulated or life-sciences environment.

TECHNICAL EXPERIENCE

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


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


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


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


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

WHO YOU ARE

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


• You understand lean thinking


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


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


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


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


• 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 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


• You have prior experience in consulting


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