Job Description

Senior Software Development Engineer - Developer Experience

Are you an engineer who loves making things work better for other engineers? Do you care about efficiency and continuous improvement? Join our team and help us redefine the way software is delivered at Capital One.

In this role, you aren't just writing code or managing infrastructure; you are a force-multiplier for our engineering teams. You will sit at the intersection of software engineering and community advocacy. You'll spend your time getting hands-on with the code that powers software delivery at Capital One, while simultaneously acting as a bridge by gathering feedback from our UK Tech organisation and sharing good engineering practices across the business.

What you'll do
  • Support and enhance the adoption and enablement of continuously evolving software delivery lifecycle platforms.
  • Operate beyond the IDE - we don't just solve problems with code; we continuously strive for the right solutions to our customers' problems, not just build tools and features.
  • Deliver core engineering features and improvements that engineers in the UK and US consume on a daily basis to deliver software at Capital One.
  • Continued support, maintenance and development of our core systems, enhancing our internal customers' journeys on their path to CI/CD.
  • Enhance our AWS deployment and validation mechanisms.
  • Build relationships and influence with platform owning teams to support prioritisation and inner-sourcing opportunities.
  • Partner with Capital One teams in the US to innersource contributions to internal developer tools.
  • Operate as a Developer Advocate, building a network of connections across engineering to hear about friction and opportunities to improve the developer experience.
What we're looking for
  • Great communicator, willing to get involved, talk to our customers, share ideas, teach and lead amongst peers.
  • Happy working across a variety of technologies and platforms to identify and solve complex problems working up and down the technology stack.
  • Real concern for improving every developer's experience.
  • Analytical mindset focused on delivering value for both the organisation and our customers, inline with stakeholder expectations.
  • Experience with infrastructure as code and CI/CD concepts.
  • Strong programming skills in one or more languages (such as Java or TypeScript).
  • Solid understanding of Amazon Web Services (AWS) or alternative cloud platforms.
  • Stickler for efficiency and effectiveness.
Where and how you'll work

This is a permanent position based in our Nottingham office. We have a hybrid working model that gives you flexibility to work from our offices and from home. We're big on collaboration and connection, so you'll be based in our Nottingham office three days a week on Tuesdays, Wednesdays and Thursdays.

What's in it for you
  • Contribute to the product roadmap for an organisation committed to transformation.
  • Drive solutions for challenges in public cloud scale, security, availability and performance.
  • Spend 10% of your time on cutting-edge innovative projects that shape our future workflow.
  • Strong career progression and training programmes including Capital One University.
  • Immediate access to core benefits: pension scheme, bonus, generous holiday entitlement and private medical insurance.
  • Flexible benefits such as season-ticket loans, cycle-to-work scheme and enhanced parental leave.
  • Open-plan workspaces and facilities designed to inspire and support you.
  • Fully-serviced gym, subsidised restaurant, mindfulness and music rooms at our Nottingham head-office.

Capital One is committed to diversity in the workplace.
