Job Description
Principal Software Engineer, Platform The mission Barclays' payments acceptance business provides critical infrastructure to the UK economy, processing billions of pounds of payments annually for both small businesses and domestic and international corporate clients.
In April 2025, we announced a long term partnership with Brookfield Asset Management to grow and transform the payments acceptance business by broadening the range of services offered, enhancing the experience for both existing and prospective clients. Leveraging extensive client relationships and deep experience of UK payments, we will create an environment of continuous innovation - activated by Brookfield's global private equity expertise in payments, technology, operational transformation and corporate carve outs - to ensure the business is strategically positioned for long term growth.
Barclays will invest approximately £400m in the new business, the majority of which will be incurred during the first three years. Performance linked incentives will drive greater alignment between the partners, underpinning the long term commitment to the transformation. Barclays and Brookfield will work to create a standalone entity over time, continuing to use the Barclaycard Payments (BPL) brand and acting as the sole payments acceptance services provider to Barclays' clients for a minimum of ten years.

Our platform & infrastructure team provide the hardened, high velocity foundations that allow our product teams to ship code to production that moves billions of pounds with total confidence.
About the role As a Principal Software Engineer for our Platform team, you are both an architect of our engineering principles and a builder of the ground we stand on. This is a high leverage position where you'll define how we scale, how we deploy, and how we maintain excellence. You'll spend your time at the intersection of deep technical strategy and hands on execution, ensuring our internal systems are as polished as our customer facing products.
What you'll be working on With a ruthless focus on optimising developer experience, you'll lead on designing, operating, and refining our internal developer platform. Leading the migration toward (or optimisation of) distributed systems, ensuring high availability and low latency.
We need to support a rapidly growing set of product engineering teams in building, shipping, and operating software quickly and safely. It's imperative we get the 'height' of the platform correct: sufficient defaults for the majority of workloads, with escape hatches where teams have a strong reason for deviating.
As members of a highly regulated industry, we hold ourselves to the highest standards when it comes to compliance, controls, and policies. We believe we can meet these standards whilst still enabling engineers to ship multiple times a day: you'll lead on the creative design and implementation of these control and compliance points within our SDLC in a way which empowers teams, rather than as stop gates.
We are building the tooling that allows us, and our product teams, to see around corners - providing monitoring, logging, and rapid incident response frameworks and playbooks to teams.
Mentorship: beyond just "code reviews," you'll be levelling up the entire engineering organization through RFCs, workshops, and fostering internal communities of practice.
What you need
Ultimately, your success is reflected in the growth of those around you. You will have mentored a new generation of senior and staff engineers, fostering a community of practice that values simplicity and automation. The platform you've built will be considered "invisible" in the best way possible: a seamless, reliable foundation that empowers every engineer at the company to do the best work of their careers.
Our guiding principles Strong opinions, weakly held - approach engineering decisions with objectivity, navigating quickly to the right balance between idealism and pragmatism. Automate everything - if you have to do it twice, it should probably be a script. If you do it three times, it's a feature for the backlog. Everything-as-code. Simplicity is a feature - we prefer boring, reliable tech over the flavour of the week, unless there's a compelling reason to trial, pilot, and switch. Ownership is absolute - we build it, we run it, we fix it. Ruthless transparency - we share our designs, our failures, and our successes transparently with the entire organisation.
The successful candidate will be based in London.
Our offices are located at 1 Churchill Place and 7 Westferry Circus (new BPL office).
We support a hybrid working pattern with 3 days per week office based presence expected.
Purpose of the role To lead and manage engineering teams, providing technical guidance, mentorship, and support to ensure the delivery of high quality software solutions, driving technical excellence, fostering a culture of innovation, and collaborating with cross functional teams to align technical decisions with business objectives.

What you need
- A storied history - you've spent significant time building complex, scalable systems. You've seen things break at scale, and you know how to prevent it

- Product thinking - you treat the platform as a product, with fellow engineers as your customers
- Craft of communication - the ability to bring both technical and non technical stakeholders on the journey with us, explaining complex technical trade offs to those who might not know what a "service mesh" is
