Senior Software Engineer - Finance Experience

As a Senior Software Engineer on the Finance Experience team, you will play a central role in delivering the systems that power seamless, automated expense reconciliation for Perk clients. Your work will span the full stack on features such as employee reimbursements, expense capture, ERP integrations, supplier invoicing, and integrations with third‑party expense platforms like Pleo and Ramp. You will partner closely with finance, compliance, and cross‑functional engineering teams to ensure every step in the financial reconciliation journey works smoothly.

Professional Responsibilities

• Shape the bigger picture. You won’t just build features; you’ll refine the what to build and why. You will contribute to your squad’s quarterly goals and long‑term vision alongside Product and Engineering leaders.
• Architect for today and tomorrow. When a major change is needed, you will write design documents that lay the foundation, manage technical debt, and ensure we invest our energy where it matters.
• Lead across boundaries. You will communicate complex ideas across teams, coordinate cross‑squad initiatives, and collaborate with architects on solution discovery.
• Raise the bar for everyone around you. As a mentor, coach, and bar raiser, you will support less experienced colleagues, provide feedback, and elevate overall engineering standards.

How We Work

We believe the best work happens when great people come together in small teams with a shared sense of purpose. Your squad will provide real ownership of features, a say in what gets built, and autonomy to deliver impactful results. We embrace AI across our workflow, using it for code reviews, documentation, and incident triage. All candidates are expected to use AI tools during interviews, and success is measured by code quality and ownership.
