Senior Developer

Senior Developer

Brand Nudge is a rapidly scaling B2B SaaS business delivering market‑leading retail intelligence data to the FMCG and CPG sectors. Our technology helps global brands such as Nestle, Birdseye and Reckitts monitor, understand and optimise their performance in a competitive retail environment. Our engineering team plays a crucial role in delivering insights at speed and scale, maintaining a robust, highly‑available platform that powers decisions for some of the world’s best‑known consumer brands.

We are seeking a Senior Software Developer to lead key architectural decisions across our Node.js/Koa backend and React/Redux front end. You’ll shape how our platform evolves, ensuring performance, resilience and reliability while mentoring junior engineers and collaborating across Product, Data and Commercial teams. This role offers the chance to work with high‑volume data, complex queries, real‑time dashboards and sophisticated visualisations—while driving best practices across the entire engineering lifecycle.

• Take a senior role in architectural recommendations for our Node.js/Koa services, ensuring performant and maintainable API design as data aggregation grows in complexity.
• Mentor developers on writing robust Postgre
  
  SQL queries (including CTE‑driven analytics), Sequelize practices and avoiding syntax/ORM pitfalls.
• Enhance instrumentation, caching and shared utilities to improve observability and platform stability under load.
• Collaborate closely with stakeholders to guarantee backend services reliably power dashboards, scorecards and analytics modules.

• Take a senior role in architectural recommendations in a complex Redux Toolkit + Saga ecosystem, ensuring predictable async flows and scalable state management.
• Guide implementation of high‑performance, data‑intensive components using d3, Highcharts, virtualization (react-window), memoization and React performance rules.
• Champion accessibility, performance, resilience and reusability across the UI layer.
• Strengthen developer experience by refining linting, formatting, Cypress e2e suites and MSW mocks.

• Oversee build/test pipelines, npm scripts, CI lint rules and release‑readiness processes.
• Maintain robust AWS integrations (Amplify, CLI, CDK) and analytics tooling (Mixpanel).

You are an experienced engineer who thrives on ownership, clarity and technical excellence. You can balance short‑term delivery with long‑term architectural thinking and have a track record of mentoring others and improving engineering standards.

• Extensive experience with Node.js, modern JavaScript/Type Script and building/optimising API services.
• Strong knowledge of Postgre
  
  SQL, CTEs, performance tuning and ORM best practices (ideally Sequelize).
• Deep experience in React, Redux Toolkit and Saga/Thunk‑based async flows.
• Familiarity with data‑visualisation tooling (Highcharts, d3) and performance optimisation.
• Experience owning deployments, CI/CD pipelines and quality tooling.
• Excellent communication skills and ability to guide technical discussions.

• Ownership of mission‑critical systems used by leading global brands.
• Hybrid working model (Reading HQ + remote flexibility).
• High autonomy and influence over technical direction.
• Opportunity to mentor and lead within a fast‑growing engineering team.
• Competitive salary.
