Job description

We're big believers in autonomous teams and iterative development. We're crazy about continuous improvement and knowledge sharing, and we want people who share our enthusiasm.

We strive to always build the right thing and build the thing right, so we place great emphasis on understanding exactly what our clients need and delivering quality products that exceed their expectations.

We think that high performing teams operate best through a model of build‑it and run‑it that comes from a deep curiosity about how our products work and how our clients use them. We use this foundation to build comprehensive product knowledge and industry expertise, but we're not dogmatic about it.

We operate in multiple build squads that operate independently but align to the same goals and ways of working. We recognise that different drives guide our roadmaps from client needs to commercial strategy to regulatory change and managing those dependencies are made through aligned team decisions.

We make client success everyone's business - what we are going to do and how we do it are team decisions.

We strongly believe that you grow expertise through hands‑on experience, rather than just theoretical knowledge, so our approach to product leadership is designed to give you deep exposure to our products, our clients, and the fintech industry really fast. And really often.

About FoundryOS

• Understanding FoundryOS capabilities, industry needs and client use cases

• Quality is at the heart of everything we do and not just a gate in a process

• Leading product roadmaps, planning and establishing best practices

• Developing expertise in the financial services industry and regulatory environments

• Building and maintaining exceptional client relationships through team excellence

• Zero-to-one function building - creating product delivery frameworks, engineering performance systems, and product delivery processes from the ground up

About the role

We’re looking for a Platform Engineer support and build core banking solutions running alongside the FoundryOS cloud platform. This role includes ongoing administration and support of some key IaaS platforms alongside FoundryOS’s core platform that is critical to the day-to-day running of our clients.

You’ll work closely with Support Engineers to ensure these IaaS platforms are supported, maintained and secured. Alongside this core part of the role, you will also be involved in the wider FoundryOS SaaS platform with other members of the team. This role includes out-of-hours on‑call support responsibilities.

What you'll be doing

• Building and maintaining cloud infrastructure across IaaS, PaaS and SaaS services, ensuring environments meet the reliability, security and compliance standards expected in regulated financial services

• Provisioning new environments using Terraform and GitHub Actions CI/CD pipelines

• Contributing to shared internal Terraform modules, improving reusability and consistency across environments

• Designing, building and troubleshooting Azure networks including VNets, NSGs, peering, DNS and connectivity between applications and third‑party solutions

• Maintaining and troubleshooting scripts, batch operations and automated processes used by core banking applications

• Writing custom scripts in PowerShell and Bash to scrape logs, surface anomalies and trigger alerts, ensuring core banking applications are proactively monitored

• Helping clients diagnose and resolve application issues at the infrastructure level, acting as a reliable second‑line support escalation

• Maintaining Azure Virtual Desktop (AVD) and end‑user client environments

• Identifying opportunities to automate manual processes using PowerShell or Bash

• Ensuring the platform meets financial services standards for security, reliability and observability

• Contributing to documentation, SOPs and internal knowledge sharing

Location

We describe ourselves as “remote but not remote only”.

We believe work can be done anywhere but relationships and trust are built best face‑to‑face. And that the best teams take ownership for themselves.

We strongly believe our people should decide where they will do the best work for the company. We don’t support presenteeism, nor do we support missing important face‑to‑face meetings to receive an Amazon delivery at home. But if you take ownership of yours and your teams’ deliveries, and will work where you need to be to get the best outcome for the company, whether that be at home, in the office in London, or meeting strategic partners, then you’re for us.
