Job Description

Own the end-to-end technical design for a cloud-agnostic engineering platform with AI-assisted capabilities, aligned to a regulated environment control and DDD domain segregation. You'll set the reference architecture, guide build decisions, and ensure the solution is operable, secure, and auditable.

What success looks like (outcomes)

  • A clear target architecture that teams can implement without interpretation gaps.
  • DDD-aligned boundaries: domains are separated, ownership is clear, and integration is deliberate.
  • Tooling choices are justified and consistent with governance (SCM/CI/IaC/GitOps/IDP).
  • AI capability is introduced safely: scoped permissions, traceability, and human approvals.

Key responsibilities

  • Define the platform reference architecture (cloud-agnostic) covering:
    • SCM/CI strategy (GitHub vs Bitbucket and implications)
    • IaC approach (Terraform/OpenTofu vs Pulumi usage guidelines)
    • Kubernetes baseline (multi-cluster, tenancy, networking, secrets)
    • GitOps with ArgoCD and promotion strategies
    • Container registry strategy and governance
    • IDP approach (Backstage/Compass) and operating model
  • Drive DDD adoption:
    • Domain boundaries, context maps, ownership model, and anti-corruption layers where needed
  • Define non-functional requirements and controls:
    • Security, resilience, observability, change management, audit evidence, SDLC controls
  • Establish architecture governance:
    • Decision records, architecture reviews, standards, and cross-team alignment
  • Align stakeholders across bank tech, security, risk/compliance, and delivery teams.
  • Design the AI-assisted ops capability with guardrails:
    • Approved automation patterns (PR creation, suggested changes, safe rollback)
    • Risk classification of automated actions
    • Human in the loop review requirements and traceability to incidents/tickets

Required experience/must-haves

  • Proven technical architecture experience in highly regulated environments (financial services strongly preferred).
  • Strong understanding of modern delivery platforms: Kubernetes, GitOps (ArgoCD), CI/CD, IaC.
  • Experience designing cloud-agnostic architectures and avoiding vendor lock-in.
  • Strong grasp of DDD and practical domain segregation (not just theory).
  • Ability to translate governance constraints into workable engineering practices.
  • Strong stakeholder management and documentation skills (bank audiences, audit audiences).

Nice-to-haves

  • Experience implementing Internal Developer Portals (Backstage and/or Compass) at scale.
  • Experience with AI/LLM-assisted developer tooling in enterprise contexts (guardrails, controls, model governance, prompt/RAG on runbooks).
  • Familiarity with security frameworks and evidence-led delivery practices.

NOTE: Hybrid, 4 days office per week.
