About the Role

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.

In the first 30 days:

• Be paired with an onboarding buddy who will introduce you to the world of equity management
• Get to know our engineering team, product managers, and designers
• Understand how your team’s surface area connects to the broader Ledgy platform
• Start contributing to the codebase with the guidance of experienced team members

In the first 3 months:

• Ship independently on impactful product features and improvements
• Participate in architecture discussions around scaling workflows, data models, and integrations
• Work alongside other engineers to implement robust, reliable data flows
• Develop a deep understanding of how companies manage and automate equity
• Participate in code reviews and help maintain our engineering standards

In the first 6–12 months:

• Take ownership of key features and improvements within your team’s domain
• Help shape the technical direction and architecture of Ledgy’s equity platform
• Collaborate with Product and Design to deliver polished, user-centric experiences
• Mentor other engineers and share expertise in automation, data modeling, and scalability

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.

Workflows & Automation — Focuses on automating complex equity workflows and integrating with third-party services, including the trading exchange. The team builds systems that help company admins efficiently onboard and offboard employees, automate equity grants and terminations, and 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.

The job is a good fit if:

• You have 7+ years of experience working as a Software Engineer
• You're excited about the impact of equity on entrepreneurship and its real-world impact for companies
• You enjoy tackling complex financial data transformations and compliance requirements
• You enjoy writing clean, maintainable TypeScript code, both in the backend and frontend
• You are excited to work with React, NodeJS, and MongoDB
• You thrive in collaborative environments and enjoy pair programming
• You take pride in creating robust, tested solutions for critical business operations

Being part of Ledgy means:

• Recharge and re-energize with flexible working hours, 25 days of vacation, and up to 40 days of remote work from outside your home country.
• We make space for your own professional development, with a generous yearly learning & development budget.
• This role will receive a competitive salary + benefits + equity. All salaries are aligned with competitively benchmarked ranges based on work location and levelling.
