The Role
Vanguard is one of the world’s leading investment management companies, trusted by millions of investors globally and powered by more than 18,800 crew members across 19 locations.
We’re looking for an experienced Application Engineering Tech Lead to join our UK-based Index Team and play a key role in our Index Modernisation programme. This initiative is transforming Index Data Management from a legacy platform to a modern, cloud‑native AWS architecture, using technologies such as Lambda, ECS, and Angular.
In this senior leadership role, you’ll shape technical direction, guide solution design, review code, and work closely with teams in the UK and US to deliver a secure, scalable, and resilient Index Management platform. While you’ll stay close to the technology, the focus is on technical leadership, architecture, and collaboration rather than day‑to‑day coding.

Previous experience of working within financial services
Experience in cloud development (AWS strongly preferred) and CI/CD technologies such as BitBucket/Bamboo and GitHub.
Experience with modern front end frameworks such as React or Angular
Experience in designing and consuming API‑driven systems, including REST and/or GraphQL
Proven ability to lead technical design, set coding standards, and perform high‑quality code reviews
Experience translating business requirements into clear technical designs and program specifications
Ability to articulate complex technical concepts clearly to non‑technical stakeholders
Strong collaboration skills, with the ability to work effectively across product, business, and engineering teams
Comfortable operating independently while also contributing as part of a high‑performing team
Ability to manage priorities and deliver outcomes in a fast‑moving, complex programme environment
Desirable Criteria
Strong backend development experience using Python, with frameworks such as Flask (or equivalent)
Experience in end-to-end testing with tools such as Cypress, Selenium and Playwright.
