Role : Java full Stack Developer

3 days a week onsite in Canary Wharf, UK.

Positions: 3

Interview : Immediate

Exp Level: 8-15 years

Must-Have skills: Strong Java Full Stack, React, Kubernetes/Docker

Role Overview: We are seeking a Senior Full‐Stack Engineer with 8+ years of experience who operates as a hands‐on, independent 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, not those with 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

• Senior Individual Contributor Mindset

Skills:

• Sr. Developer with hands on experience in Java based development & React

• Experience in building responsive, component based user interfaces using modern front end frameworks

• Hands on expertise in API design and development (REST/JSON), including versioning and backward compatibility

• Experience with UI testing, component testing, and front end 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
