The Opportunity
We’re seeking a Full Stack Developer to help Excellis build, modernize, and accelerate AI-enabled software solutions across our internal products, client platforms, and emerging AI development workflows. This role is ideal for a developer who is not only strong across the front end and back end, but also comfortable using AI tools as part of the daily engineering process.
You’ll work with modern development tools, AI coding assistants, Git-based workflows, prompt-driven development, and agentic engineering practices to help us move faster, improve quality, and build reusable software components. This role will support Excellis initiatives including CUE product development, AI workflow enablement, client-facing prototypes, integrations, internal tooling, and scalable platform architecture.
We are looking for someone who can code, think, prompt, test, collaborate, and continuously improve how software gets built in an AI-enabled environment.

In This Role You Will
- Build and maintain full stack applications across front-end, back-end, API, database, and integration layers.
- Use AI-enabled development tools such as Cursor, Claude Code, Codex, GitHub Copilot, or similar platforms to accelerate development, debugging, documentation, testing, and refactoring.
- Work within Git-based workflows using Bitbucket, GitHub, pull requests, branches, commits, code reviews, and release processes.
- Translate business requirements, user stories, prompts, and technical concepts into clean, scalable, production-ready software.
- Support the development of reusable components, modular features, APIs, connectors, and AI-enabled workflow patterns.
- Collaborate with product, strategy, UX, QA, and engineering teams through Agile, Kanban, and iterative delivery models.
- Help define and refine AI-assisted development practices, including prompt patterns, coding loops, review loops, testing loops, and documentation standards.
- Contribute to CUE platform development and other Excellis product initiatives with a focus on scalability, maintainability, and repeatable deployment.
- Integrate third-party services, APIs, AI tools, data sources, and enterprise systems into modern web applications.
- Review AI-generated code for quality, security, performance, maintainability, and alignment with architecture standards.

Job Responsibilities
- Develop front-end interfaces using modern JavaScript/TypeScript frameworks and component-based architecture.
- Build back-end services, APIs, data models, integrations, and business logic to support scalable applications.
- Work with AI coding tools to generate, review, improve, and test code while maintaining engineering discipline and human oversight.
- Create and maintain reusable libraries, shared components, templates, and development patterns.
- Participate in sprint planning, backlog refinement, Kanban workflows, story estimation, technical design, and delivery tracking.
- Use Git, Bitbucket, GitHub, and related tools to manage source control, branching strategies, pull requests, releases, and code reviews.
- Write clear technical documentation, implementation notes, AI prompts, setup instructions, and developer handoff materials.
- Debug, troubleshoot, and optimize application performance across front-end, back-end, database, and integration layers.
- Collaborate with QA to support automated testing, regression testing, acceptance criteria, and release validation.
- Partner with senior technical leads to improve architecture, code quality, security, deployment practices, and AI-assisted development standards.
- Evaluate emerging AI development practices and help Excellis apply them in practical, secure, client-ready ways.
- Support proofs of concept, prototypes, internal tools, and client-facing demos that show how AI can improve workflows and software delivery.

Ideal Match
- A hands-on full stack developer who is excited about building software in a modern AI-enabled engineering environment.
- Comfortable using AI tools as a force multiplier, but disciplined enough to validate, test, and improve the output.
- Strong problem-solver who can move from ambiguity to working software.
- Collaborative team player who communicates clearly with technical and non-technical stakeholders.
- Curious, adaptable, and motivated to stay current with AI development tools, agentic workflows, and modern engineering practices.
- Understands that AI can accelerate development, but quality, architecture, security, and maintainability still matter.
- Comfortable working in a fast-moving environment where requirements evolve and iteration is part of the process.
- Interested in helping Excellis build reusable, scalable, productized solutions rather than one-off custom development.
