The Full Stack Engineer is a hands-on developer responsible for building and evolving features across Enhance Group's proprietary technology platform, Connect. The role is a lead builder on a significant new programme of platform development, working alongside the existing engineering team to extend Connect into new areas.

The role is created to deliver this programme and continues afterwards as a permanent engineering capability supporting Connect's wider roadmap. The successful candidate works closely with the Head of Engineering, the existing engineering team, and Enhance's design partner.

The Engineer translates designs and product requirements into well-tested, maintainable code across the full stack. The role combines independent feature delivery with collaboration on architecture and standards, working within the established conventions of a mature codebase rather than building in isolation.

Key Responsibilities

Feature Delivery

Build and ship full-stack features across Connect, from data model and backend logic through to user-facing screens.
Take ownership of discrete areas of work, delivering independently within agreed architecture and standards.
Translate designs into accurate, responsive, accessible front-end implementations.
Break work down into deliverable increments and track progress through the team's planning process.

Backend and Data

Develop and maintain backend systems in Ruby on Rails, including RESTful APIs, background jobs, and workflow logic.
Design and evolve data models in MySQL, with attention to consistency, performance, and maintainability.
Implement robust authorisation and access-control logic, with care for data segregation and security.
Build and consume third-party integrations, including external APIs and CRM systems.

Front End

Build front-end applications and components in React and TypeScript, consuming and extending the platform's design system.
Implement data visualisations and interactive analytics views.
Maintain a high standard of usability and visual fidelity, working from design specifications and collaborating with the design partner where detail needs resolving.

Reporting and Document Generation

Contribute to Enhance's reporting and document-generation capabilities, building new report outputs.
Integrate reporting into the wider platform, re-using existing calculation logic rather than duplicating it.

Engineering Standards

Write clear, well-tested code, following the team's conventions for test-driven development and automated testing (RSpec and front-end testing frameworks).
Participate in code review, both submitting work for review and reviewing others' contributions constructively.
Use the team's version control, branching, and continuous-integration practices, and contribute to safe, repeatable deployment.
Help troubleshoot and resolve technical issues across the stack, escalating architectural decisions to the Head of Engineering where appropriate.

Collaboration and Continuous Improvement

Work closely with the Head of Engineering, the engineering team, the design partner, and colleagues across the business.
Contribute to architectural discussions, surfacing trade-offs and flagging risks early.
Support the controlled adoption of automation and AI-assisted capabilities where they deliver measurable value.
Support new features through to launch, responding to user feedback.

Skills, Knowledge and Expertise

Solid commercial experience with Ruby on Rails, including building and consuming RESTful APIs.
Strong proficiency in modern front-end development using React and TypeScript.
Experience with relational databases (MySQL or similar), data modelling, and query performance.
A working discipline of automated testing (TDD, RSpec, or equivalent) and the habit of writing tested code by default.
Comfortable working within an established codebase, respecting existing patterns and conventions rather than reinventing them.
Experience integrating third-party APIs, including authentication, error handling, and rate considerations.
Familiarity with Git-based workflows, code review, CI/CD pipelines, and modern deployment practices.
Experience with Agile delivery and breaking features into incremental, shippable work.
Exposure to data visualisation or charting libraries is an advantage.
Exposure to Node.js / NestJS or templating-based document rendering is an advantage, though not essential.
A practical interest in AI and data-driven systems, and the judgement to assess where they genuinely add value.
Strong written and verbal communication, and the ability to work collaboratively with non-technical colleagues and external partners.
