About the role
We need a Platform Engineer to take ownership of the technical foundation behind a bank's Branch Automation platform.
This is not a greenfield build — it's an undocumented, live environment spanning Oracle Cloud Infrastructure (OCI), internal services, banking middleware, and third-party integrations.Your core mission: make sense of this landscape.
You'll map infrastructure and networks from scratch, discover and document integration points, reverse-engineer undocumented APIs, write validation test scripts, and build the CI/CD and cloud infrastructure to support ongoing delivery.A key workstream involves establishing connectivity with Temenos Infinity (Quantum Fabric) — either consuming its APIs or exposing new ones — and applying that same rigor across the entire estate.This role suits someone who's comfortable with ambiguity, treats documentation as a real deliverable (not an afterthought), and can move confidently across infrastructure, integration, and automation work.What you'll do:
Conduct full environment discovery: infrastructure, network topology, service dependencies, data flows — and turn it into structured documentation (diagrams, network maps, service/integration registers)Catalogue all integration points across the estate (Temenos Infinity, core banking platforms, government portals, payment gateways, legacy services)Reverse-engineer undocumented APIs (probing endpoints, traffic analysis) and produce formalOpenAPI specs / Postman collectionsWrite automated test scripts (Postman/Newman, pytest, or k6) that plug into CI/CDInvestigate and implement Temenos Infinity/Quantum Fabric connectivity — SOAP-to-REST bridging, middleware orchestration, ADRs, and integration runbooksProvision and manage OCI services (Compute, VCN, Load Balancer, OKE, Object Storage, Vault, OCI DevOps) via Terraform/Resource ManagerManage Docker/Kubernetes (OKE) workloadsBuild and own CI/CD pipelines (GitLab CI / GitHub Actions / Jenkins) with test gates, SAST scanning, and environment promotion
