À propos
About VE3 : VE3 is a UK-based technology consultancy and product innovation company delivering cutting‑edge digital transformation across public sector, enterprise, and regulated industries. We combine deep engineering expertise with an agile, product‑led mindset to build scalable, secure, and data‑driven platforms for our clients.
We are looking for a Senior Software Engineer (Full‑Stack) to join our engineering team on a major transformation programme. The ideal candidate is an experienced technologist who thrives on end‑to‑end delivery — from front‑end experience optimisation to scalable, observable, and secure backend design.
Role Overview : As a Senior Software Engineer, you’ll play a pivotal role in designing, implementing, and maintaining modern, high‑performance web applications using Next.js, TypeScript, and GraphQL. You’ll operate within an agile delivery team, collaborating closely with architects, product owners, and DevOps engineers to ensure robust, maintainable, and accessible software delivery aligned to enterprise standards.
This is a full‑stack role that demands strong technical judgment, a focus on developer experience and testability, and a deep understanding of modern frontend and backend integration patterns.
This is a delivery‑critical role, and immediate availability (or short notice period) is highly desirable.
Responsibilities
Design and develop full‑stack web applications using Next.js 13 / 14 (App Router), React 18, and TypeScript.
Implement performant, accessible, and responsive UI components aligned with WCAG 2.2 AA standards.
Architect, document, and evolve GraphQL schemas, resolvers, and contracts, ensuring consistent API design and validation.
Build and optimise PostgreSQL data models, including schema migrations, indexing, and query tuning.
Design serverless event‑driven backends using Cloud Functions (GCP) and Pub / Sub, following principles of idempotency and least‑privilege access.
Maintain code quality through TDD, static analysis, automated testing, and CI / CD pipeline discipline.
Implement observability through structured logs, metrics, and distributed tracing with OpenTelemetry.
Contribute to continuous improvement of DevSecOps practices — from OAuth / OIDC security to SonarCloud quality gates and threat modelling.
Participate in agile ceremonies (planning, stand‑ups, retrospectives) and maintain close communication with stakeholders and cross‑functional teams.
Produce clear, maintainable technical documentation, including architecture decision records (ADRs), runbooks, and schema notes.
