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 fullstack applications, from frontend user experiences to backend 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 system performance and reliability.
  • 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, Frontend development, Backend services & Infrastructure and platform operations.
  • Senior Individual Contributor Mindset.

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.
  • Experience in automating the workflows and repeatable tasks.

Work Location

Hybrid: 3 days/week on client site (London Canary Wharf), 2 days/week remote.
