Staff/Senior Software Engineer

As a Senior/Staff Software Engineer at Ledgy, you’ll design and build elegant, scalable systems that power how companies manage their equity. You’ll collaborate with fellow engineers (based mainly in Zurich and London), product managers, and designers to develop industry-leading automation and experiences — while many in our space still rely on manual processes.

Location: We hire remotely across the UK, Spain, Germany, Poland, and Romania. For candidates based in London, we use a hybrid model with 2 days in the office per week.

Teams we’re hiring for:

Core Equity — Owns the foundational logic that powers Ledgy’s equity engine. Every equity-related event — such as issuing shares, creating new pools, or adjusting ownership — generates transactions. This team defines and maintains the transaction logic, data model, and core domain behaviour that ensure Ledgy’s platform remains accurate, scalable, and compliant. They also enable employees to sell their shares seamlessly once vested.

Reporting — Transforms Ledgy’s core equity data into financial, operational, and compliance reports. The team manages large, complex datasets and ensures reporting is accurate, performant, and reliable across jurisdictions and company structures. Their work powers the insights companies and auditors rely on for decision-making and transparency.

AI Systems — Develops Ledgy’s AI foundations and product experiences, from AI agents and AI-assisted workflows to the platform capabilities that help other teams embed AI safely in their domains. The team works in a new and evolving product area, balancing rapid iteration with reliable execution, evaluation tooling, and responsible automation.

Tax — Ensures taxes are correctly reflected throughout equity operations, especially moments such as exercising, selling, mobility, and other taxable events. As a future team, Tax will build end-to-end product capabilities across the stack, helping customers manage complex tax and compliance requirements accurately across jurisdictions.
