Role Description

We're looking for a Senior Software Engineer who takes real ownership of their work — someone who can pick up a specification, ask the right questions, and deliver a complete, production-ready feature without needing their hand held at every step. You're comfortable on both sides of the stack, and you care deeply about the quality and longevity of the code you ship.

You'll work primarily within our MERN stack — MongoDB, Express, React, and Node.js — building and scaling SaaS features used by customers globally. You write efficient, well-documented code and you understand that performance isn't an afterthought: it's part of getting the job done properly.

This is a role for someone who is technically sharp and professionally self-sufficient. You thrive in an agile environment, collaborate well across disciplines, and are never too senior to write docs, improve a test, or jump in on an incident. If that sounds like you, we'd love to talk.

Key Responsibilities

Work independently to understand functional specifications and deliver complete, production-ready features end-to-end
Contribute to both frontend and backend codebases, designing and implementing features across the full MERN stack
Write high-quality, performant, and reliable code on defined tasks and bug fixes with minimal supervision
Collaborate on system design discussions, API design, and data modelling to ensure clean integration across layers
Develop and maintain backend services with a focus on microservice architecture, performance, and reliability
Write clean, testable, and well-documented code — documentation is part of the definition of done, not an afterthought
Participate actively in code reviews, providing constructive and thorough feedback to peers
Identify and address performance bottlenecks on both client and server sides, applying optimisation best practices
Write and maintain unit, integration, and end-to-end tests to ensure system reliability
Contribute to the continuous improvement of engineering practices, tooling, and standards
Work closely with Product, QA, and Design to build scalable, user-centred features that meet real customer needs
Participate in team agile ceremonies — planning, standups, reviews, and retros — and contribute to their ongoing evolution
Join the on-call rotation and respond to production incidents within defined SLAs with urgency and calm
Collaborate with senior engineers on architecture decisions and raise technical concerns proactively

Requirements

Must Have

Experience

5+ years of professional software engineering experience in a product or SaaS environment
Demonstrable ability to work independently — owning a feature from specification through to deployment
Bachelor's degree in Computer Science, Software Engineering, or equivalent practical experience

MERN Stack Proficiency

Strong hands-on experience with the full MERN stack: MongoDB, Express.js, React, and Node.js
Deep proficiency in TypeScript and modern JavaScript (ES6+) — you know the language, not just the frameworks
Solid HTML, CSS / SCSS fundamentals with a strong understanding of responsive design and UI/UX best practices
Client-side state management experience: Redux, React Context, or equivalent
Working knowledge of RESTful API design and backend service architecture

Performance & Optimisation

Strong understanding of client-side performance optimisations: lazy loading, code splitting, rendering strategies, caching
Backend optimisation awareness: query efficiency, indexing, connection pooling, and service-level performance profiling
Understanding of how modern browsers work, their constraints, and how to write code that accounts for them
Experience with microservice-based architecture and distributed system fundamentals

Code Quality & Documentation

Consistent track record of writing efficient, maintainable, and well-documented code
Experience with testing frameworks: Jest, React Testing Library, and/or Enzyme
Proficiency with JS ecosystem tooling: webpack, ESLint, and standard build pipelines
Comfortable working with Git and collaborative version control workflows (branching, PRs, code reviews)

Engineering Fundamentals

Solid grasp of OOP principles, data structures, and algorithms
Experience with real-time technologies: WebSockets, Socket.IO, or server-sent events
Familiarity with UI component libraries such as Ant Design, Material UI, or Bootstrap

Nice to Have

Progressive Web App (PWA) development experience, including service workers and offline-first strategies
AWS frontend infrastructure familiarity: S3, CloudFront, CDN configuration
CI/CD exposure — pipeline configuration, automated deployments, environment management
Docker experience and comfort working in containerised local or production environments
Background in a SaaS or product-led company building software at meaningful scale
Experience integrating third-party backend services and designing clean abstraction layers around them
