Are you a seasoned cloud engineer who enjoys owning platforms end‑to‑end? Ready to shape how a modern core‑banking engine runs in production instead of only deploying other people’s decisions? At Ohpen, a cloud‑native fintech, this Senior Cloud Engineer role offers the chance to design, automate and operate business‑critical AWS infrastructure at scale. Join a small, expert team where decisions are made quickly, ideas are taken seriously and good engineering is the default. In this role, you join a three‑person Cloud Engineering team that owns deployments and self‑service environments for the Savings & Investments part of Ohpen’s core‑banking platform. Most of the work is driven directly by the team: designing AWS architecture, standardizing Terraform modules and building the tooling that gives developers safe, self‑service access to infrastructure. Your day‑to‑day focuses on making the platform reliable, secure and easy to operate - automating everything from environment provisioning to deployments, tightening monitoring and observability and resolving complex incidents across infrastructure and networking. As part of a four‑person on‑call rotation, you help triage alerts and fix production issues — and then use what you’ve learned to lead modernization efforts from legacy setups to cloud‑native designs, improve platform security and influence architectural decisions that directly impact reliability, performance and cost. You have at least 5+ years of hands‑on experience with cloud technologies , ideally including AWS ‑based infrastructure in production. You are fluent in Terraform and infrastructure‑as‑code , and comfortable working across networking, Windows/Linux systems and CI/CD pipelines . You script confidently in Python , Bash or PowerShell and use automation, monitoring and observability tooling to keep complex distributed systems healthy. You understand cloud security principles and IAM, and know how to build secure, compliant setups for regulated or security ‑focused environments. You haven’t updated your CV in a while?
