Sr. Backend Software Engineer Remote, UK in Basingstoke

Addepar is a global technology and data company that helps investment professionals provide the most informed, precise guidance for their clients. Hundreds of thousands of users have entrusted Addepar to empower smarter investment decisions and better advice over the last decade. With client presence in more than 50 countries, Addepar's platform aggregates portfolio, market and client data for over $8 trillion in assets. Addepar's open platform integrates with more than 100 software, data and services partners to deliver a complete solution for a wide range of firms and use cases.

The Investor Solutions team at Addepar is growing! Navigator is a quantitative liquidity risk projection tool that is one of the key components of Addepar's multi-product ecosystem. Brought into the Addepar family as part of an acquisition in 2021, Addepar has continued to double down on investing in this critical product, as we've scaled well beyond the multi-million ARR goal first set for this product line. Going into 2026, Navigator will be used as the foundation to build key workflows that cater to large institutions, further integrating across the Addepar ecosystem.

As we continue to scale, a need has opened up for a Senior Backend Software Engineer who would bring to bear their unique expertise with the existing Engineering team, with exciting opportunities to extend the scope for this role longer term, as the product continues to push onward into future global expansion mode.
