Role Purpose

The DevOps Engineers will play a key role in the strategic design, hands‑on delivery, and oversight of workstreams relating to Cloud Platform, DevOps, Security and Network support for the Fnality Payment System. As the SME, this person will be tasked with auditing the current technology ecosystem and making recommendations which future‑prove the Platform model to support long‑term business growth. Having worked in a similar industry, the DevOps Engineer will have the knowledge and experience, basing their decision‑making around considerations relating to the storage of highly sensitive data. The engineer will be expected to be a proactive and confident practitioner of AI technologies, continually identifying responsible, secure and practical ways to use AI to increase their own throughput, improve the quality of engineering outcomes, and help the wider team deliver faster and more effectively.

We are looking for two DevOps engineers, one to be based out of our London office (hybrid) and one to work out of our Connecticut office (hybrid).

Role & Responsibilities

• Apply your deep knowledge of Kubernetes and the application stack to bring new services to production through resilient, fully automated, cloud‑native delivery.
• Deploy and support Fnality‑highly resilient and scalable technology products and platforms to customers.
• Demonstrate strong security awareness, with the ability to identify potential vulnerabilities and proactively remediate security risks.
• Work with the wider team to create, maintain and deliver against an organised and cross‑organisation aligned backlog of delivery and support operations.
• Collaborate with Development, QA, Cyber Security, and SRE teams to deliver platform changes and ensure smooth, reliable operations.
• Maintain and enforce compliance standards across the platform, embedding controls into day‑to‑day engineering and operations.
• Drive observability and resilience by owning application monitoring, alerting, and event management.
• Review technical designs and provide well‑founded input or challenge assumptions based on practical experience and industry best practices.
• Contribute to 24×7 operational support and incident management – please note our on‑call requirements are not fully defined as yet, but there will eventually be an element of this.

Skills And Experience

• Hands‑on experience with AI‑enabled engineering workflows, including agentic AI tools, code assistants, and automation patterns that improve platform delivery and operational effectiveness. Ideally with Claude or Copilot.
• Ability to integrate AI capabilities responsibly into DevOps and CI/CD practices, with consideration for security, governance, data protection, and safe use in regulated environments.
• Experience working as a DevOps/Cloud/Platform Senior or Lead Engineer as it relates to the seniority and complexity of the role.
• Experience of successfully delivering secure, large‑scale projects in a cloud environment.
• Experience in supporting the development of DevOps pipelines.
• Mandatory knowledge:
  • Kubernetes and related tools (e.g.: Docker, Helm, Flux, EKS)
  • CI/CD implementation and source control (GitLab/GitHub)
  • Terraform and Infrastructure‑as‑Code
  • Main AWS services (EC2, ELB, S3, RDS, etc.) and architecture concepts
  • Knowledge of some of the following tech stack: scripting languages, AWS multi‑account structure, Java and Golang, SSO integration (AD/Okta), understanding of network and security concepts
• Strategic, forward‑thinking approach with a passion for innovation and change.
• Willingness to get involved with a multitude of work and changing priorities in a fast‑paced, ambiguous environment.
• Comfortable working with limited resources and tight deadlines.

Ideally you will have

• Experience in a DevOps Engineer role adhering to regulatory compliance and information security management frameworks (e.g., ISO27001, NIST, etc.) and as of late had chances to flex your competency, ideally in an agile, fast‑growing scale‑up.
• Platform Engineering expertise (e.g., service, design, engineering) coupled with an understanding of financial services and relevant regulations and laws.
• Knowledge of and/or interest in blockchain, security operations, financial services back‑office processes, systems and products.

However, if your experience isn’t an exact match, please apply if you are interested and we can see if there is a potential opportunity for you with Fnality.

We employ curious individuals who thrive working in a fast‑paced and constantly changing environment, who work best when empowered to drive their own work, and who are not afraid to fail fast and learn quicker.

You will be an analytical thinker who is able to look at tasks and understand the most efficient way to achieve the desired outcome. You will be vigilantly outcomes‑focused and fully agile in your approach to working. You will have an insatiable desire to learn, adept at picking up new challenges and giving it a go. You will want to deliver as much as learn and you will understand how important the power of the team is.

These roles will be either London or Connecticut based and you must be eligible to work in the UK or the US. Please note we cannot sponsor visas for these roles.

A bit more about us

Digital transformation is changing our lives, work and businesses. While other sectors evolve however, financial markets remain slow, fragmented and siloed. What the world needs now is a future‑facing financial system for the digital age.

At Fnality, we have been speaking – and listening – to the real users of today’s financial systems. From businesses to banks, there is a clear, collective ambition for a simpler, faster, safer and more resilient payment system; one that can move and settle money quickly and efficiently, with minimised risk and much more transparency.

Fnality Global Payments

We are building a new payment system that will enable tokenised, peer‑to‑peer markets.

Fnality Global Payments (FnGP) will comprise a series of national systems, each regulated in its home jurisdiction. We call each of these a Fnality Payment System (FnPS).

In each payment system, a Fnality settlement asset will act as the settlement/payment asset for any Payment (P), Delivery v, Payment (DvP) or payment vs. payment (PvP) need.

FnGP are underpinned by Distributed Ledger Technology (DLT). The nature of DLT is such that it enables FnGP to:

• Allow for immediate settlement
• Interoperate across business platforms and jurisdictions

The key benefits of the above are:

• Reduced counter‑party and credit risk
• Reduced operational risk
• Efficient liquidity management
• An ability to move resources from risk mitigation to business growth
