NTT DATA is currently looking for a Senior Fullstack Engineer (hybrid working) for our growing team in the UK.

Role Overview

We are seeking a Senior Fullstack Engineer with 8+ years of experience who operates as a hands ‑ on contributor and takes full ownership of building, scaling, and running production systems. This role is designed for engineers who have built and operated large ‑ scale systems end ‑ to ‑ end, beyond superficial exposure or purely design ‑ focused experience. The ideal candidate demonstrates depth of experience over tenure, understands the business impact of engineering decisions, and is comfortable owning both product delivery and “run ‑ the ‑ bank” responsibilities in complex environments.

Key Responsibilities

• Design, build, and operate end ‑ to ‑ end full stack applications, from front end user experiences to back end services and infrastructure.
• Own the entire software lifecycle, including design, development, testing, deployment, monitoring, and production support.
• Build and operate systems using modern GitOps ‑ driven SDLC models, ensuring reliable and repeatable deployments.
• Develop highly scalable, performant, and resilient systems, with strong attention to:
• Actively participate in production operations, incident resolution, and system optimization, embodying true “you build it, you run it” principles.
• Collaborate closely with product and business stakeholders, translating requirements into robust technical solutions while understanding downstream business impact.

Experience

• Proven ability to operate as a senior IC, delivering production systems—not just high ‑ level designs or architectural diagrams.
• Comfortable making and owning technical decisions in ambiguous, fast ‑ moving environments.
• Demonstrated experience building systems of meaningful scale and complexity—engineers who have been “scarred” by real ‑ world production challenges.
• Strong hands ‑ on experience across Full ‑ Stack & Platform Expertise, Front end development, Back end services & Infrastructure and platform operations

Skills

• Deep knowledge in Fullstack development, with hands on experience in Java‑based development & React
• Experience in building responsive, component‑based user interfaces using modern frontend frameworks
• Hands‑on expertise in API design and development (REST/JSON), including versioning and backward compatibility
• Experience with UI testing, component testing, and frontend build tooling
• Deep familiarity with Kubernetes ‑ based environments, including deployment, scaling, and operational considerations.
• Experience in CI/CD pipelines, GitOps workflows, A/B testing strategies etc.
• Experience in automating the workflows and repeatable tasks

Our people are the most critical component of our long‑term success and their health and wellbeing are our priority. You will enjoy a comprehensive, locally competitive benefits package.
