Python jobs in United Kingdom

We know that people want great value combined with an excellent experience from a bank they can trust, so we launched our digital bank, Chase, to revolutionise mobile banking with seamless journeys that our customers love. We're already trusted by millions in the US and we're quickly catching up in the United Kingdom – but how we do things here is a little different. We're building the bank of the future from scratch, where you'll have the opportunity to make a real impact.

As a Lead Software Engineer at JPMorgan Chase within the International Consumer Bank, you will collaborate closely with product, platform and development teams to design and operate a first-class observability capability across our cloud-native microservices. You’ll set standards and architect, build and design tooling for metrics, logs and traces telemetry data, across all stages of the SDLC, delivering end-to-end cutting-edge solutions to enhance the developer experience. Our Developer Experience team is at the heart of this venture, dedicated to providing an exceptional developer experience for all our engineers. We're looking for people who have a curious mindset, thrive in a collaborative environment, and are passionate about new technology. By their nature, our people are also solution-oriented, commercially savvy and have a head for fintech. We work in tribes and squads that focus on specific products and projects – and depending on your strengths and interests, you'll have the opportunity to move between them.

While we’re looking for professional skills, culture is just as important to us. We understand that everyone's unique – and that diversity of thought, experience and background is what makes a good team, great. By bringing people with different points of view together, we can represent everyone and truly reflect the communities we serve. This way, there's scope for you to make a huge difference – on us as a company, and on our clients and business partners around the world.
