Senior DevOps/SRE Engineer

Senior DevOps / SRE Engineer

This is a remote position within the UK. We currently don’t provide visa sponsorship. 

We are a B2B Fintech focusing on disrupting the small business lending market. SMEs make up 99% of all UK businesses yet are traditionally underserved by big banks and financial institutions. Built from nearly a decade of experience powering a digital credit broking marketplace, our SaaS solutions serve banks, lenders, and the wider SME finance ecosystem. Leveraging live, validated transactional data from the UK’s advanced data environment, FXE Technologies’ products drive accurate decisioning and proactive engagement. Our products are used by over 80 leading high street and challenger banks and specialist lenders

Role Description

Behind those products is a platform that has to earn the trust of the institutions that depend on it. FXE is a lean, fast-moving organisation with strong ambitions, and the DevOps team sits at the centre of it. We build and operate multi-tenant platforms used by customers including Tier 1 banks, so everything we build must meet the security, reliability and scale expectations of regulated financial institutions.

It’s an exciting time to join. We’re delivering several projects that will shape where FXE goes next, and the DevOps team is critical to making them happen.

We’re looking for a Senior DevOps Engineer to take real ownership of DevOps at FXE. You’ll bring deep, hands-on infrastructure and networking expertise, a strong command of Terraform, AWS, identity and access management, delivery pipelines and observability, and recent, extensive experience running infrastructure through automation.

Your decisions on infrastructure, delivery pipelines, operations, FinOps, maintainability and reliability, together with the product and application architecture decisions you help shape, will directly determine how fast the business ships, how confidently it scales and how well it holds up under pressure.

This isn’t a role where you quietly maintain someone else’s designs. You’ll create and help define them. You’ll lead infrastructure and delivery initiatives end to end, hold your own in design and planning discussions with the most experienced engineers in the company, and bring modern DevOps, SRE and security thinking to how we build, deploy and run systems.

You’ll also be a bridge between DevOps and Engineering. You’ll understand infrastructure deeply, but you’ll also be able to read, reason about and ideally contribute to application code, so that platform and application decisions are made together rather than handed over a wall.

Beyond product infrastructure and delivery pipelines, the DevOps team is responsible for FXE’s security systems, supports our corporate IT infrastructure (including Microsoft 365 and our zero-trust network access), and assists with compliance activity such as SOC 2 and Cyber Essentials Plus. This role shares in all of that, not just product-facing infrastructure.

If you want a role where your judgement genuinely counts, where your thinking will be challenged rather than rubber-stamped, and where the scope runs from network design to production reliability to shaping how Engineering and DevOps work together, this is it.

What you’ll do

Infrastructure & platform

• Design, build and operate cloud infrastructure on AWS, with a strong emphasis on IAM and identity services, compute and container services such as EC2 and EKS, networking (VPC design, routing, service mesh, load balancing, DNS, connectivity, segmentation and security boundaries), database services, serverless (e.g. Lambda, Step Functions) and analytics services.
• Own infrastructure-as-code using Terraform and the delivery pipelines that move code changes across environments.
• Design for resilience, maintainability, availability (multi-AZ, failover, self-healing, backup and recovery), security and operability (observability, alerting, capacity), and overall functional and non-functional suitability, efficiency, and effectiveness.
• Securely and reliably integrate and configure 3rd party services used to complement the AWS environment.
• Use languages such as Python to automate DevOps tasks and support production capabilities owned by DevOps
• Identify, document, and remediate as necessary infrastructure and platform-level technical risks following established processes.

Delivery pipelines and developer experience

• Design, build and maintain software delivery (CI/CD) pipelines t…
