Full Stack Lead Java Developer at Department for Work & Pensions, UK Office/Remote, 12 Months, £Contract Rate

This role will support delivery within the Health Assessment Efficiencies (HAE) Workstream, which focuses on delivering measurable efficiency improvements in health assessments through service transformation, digital innovation, and process optimisation within a 12 -18-month timeframe.

The work includes mobilising and delivering a prioritised set of initiatives designed to reduce administrative burden and improve clinical/operational processes. This includes initiatives such as Write Up Assistant, Transcription & summarisation, Case summarisation, NHS data share, and audit/process optimisation (for example: "group/remove audit attributes, " "automate/streamline amendments, " and WCA intelligent audit). Delivery will be scaled based on evidence of outcomes and governance decisions.

The work will be delivered via a multidisciplinary team using agile ways of working (clear prioritisation, sprint planning, reviews, and continuous improvement) with appropriate delegated decision-making to maintain pace and focus.

As a Lead Full Stack Java Developer, you will be required to operate with significant autonomy, providing expert technical leadership and assurance across the engineering lifecycle. This includes:

• Setting technical direction for engineering work within the team and contributing to wider service architecture and delivery patterns.
• Ensuring engineering quality, defining, and maintaining standards, patterns and principles that underpin delivery across HAS/PIP services.
• Providing specialist technical advice to Product Managers, Delivery Managers, Architects, and teams, ensuring decisions align with broader programme goals.
• Coaching and mentoring engineers, supporting capability development across software engineering, DevOps, testing, and secure delivery.
• Leading on problem resolution, using judgement and expertise to manage complex technical risks, incidents, and architecture trade xe2 offs.
• Influencing multi xe2 team delivery, ensuring consistent technical practice, and shaping the approach to creating scalable, reliable, and secure digital services

Experience and Skills

• Full xe2 stack engineering expertise with hands xe2 on experience delivering complex digital services using modern languages (Java, Node) and frontend frameworks (React, Angular, TypeScript/JavaScript). Able to design, build and maintain high xe2 quality, reusable components and services aligned to DWP engineering standards.
• Strong cloud engineering capability, particularly AWS. Able to design, configure and operate cloud xe2 native services (compute, networking, IAM, VPC design, storage patterns), including secure xe2 by xe2 design practices. Experience with serverless patterns, microservices, and event xe2 driven architectures.
• AI xe2 related engineering capability to support the innovation workstreams. Experience integrating LLM/ML services, validating model outputs, designing deterministic and non xe2 deterministic test scenarios, managing prompt evaluation, and incorporating guardrails for responsible AI. Experience working with model xe2 driven APIs (e.g., Bedrock, OpenAI) is desirable and directly relevant to the workstream needs.
• Infrastructure xe2 as xe2 Code delivery using Terraform or equivalent tooling, including modular environment provisioning, automated compliance, configuration management, and consistent environment replication.
• DevOps and CI/CD engineering, including GitLab/Jenkins/GitHub Actions, automated build/test/deploy workflows, dependency security scanning, quality gates, and integration of controls required for operating in highly regulated environments.
• Containerisation and platform engineering, including Docker and, ideally, orchestration using Kubernetes/EKS. Ability to diagnose and mitigate platform issues, performance bottlenecks, and environment variations.
• Testing and quality assurance leadership, with experience embedding shift xe2 left practices in pipelines, including unit, integration, E2E, API/contract, load/performance, and security testing. Strong understanding of observability xe2 driven validation, using logs, metrics, and traces to ensure service reliability.
• Practical experience of engineering secure services in regulated environments, including authentication/authorisation patterns, encryption, audit, data minimisation, network restrictions, and secure operational workflows.
• Strong software craftsmanship discipline, including code quality tooling (e.g., SonarQube), automated dependency management, refactoring for maintainability, and promoting best xe2 practice engineering habits across teams.
• Excellent collaboration and stakeholder engagement skills. Able to explain technical decisions to non xe2 technical stakeholders, influence direction across multi xe2 disciplinary teams, and work closely with Product, Architecture, QA, User xe2 Centred Design and Operations.
• Experience operating within multi xe2 team, agile delivery environments, contributing to sprint planning, backlog refinement, roadmap discussions, and continuous improvement.
• Domain awareness of GOV.UK xe2 based services or public xe2 sector delivery environments, including secure data handling, auditability, resilience, and user xe2 centred service delivery patterns.
