Job description

We are seeking a Staff Software Engineer to join our Engineering team at our corporate headquarters in Addison, TX. This is the senior individual-contributor engineer on Jani-King's software team and the owner of its engineering quality bar — setting the standard for how code is designed, reviewed, tested, and shipped.

Jani-King's engineering team builds and operates a proprietary franchise accounting platform — a React, .NET, and SQL Server system hosted in AWS — that manages billing, payments, settlements, and period-end accounting for franchise owners nationwide. This is a hands-on role, but "hands-on" no longer means typing out programs line by line: our team builds with AI coding agents as the primary means of production, and you'll own architecture, run a rigorous review practice on agent-produced work, and mentor a mixed team of employees and contract developers.

• Engineering Standards: Own the code review standard across all repositories, and serve as final human reviewer on financial calculation, data migration, and authorization code.
• Team Leverage: Provide day-to-day technical direction to contract developers and mentor engineers through pairing and structured review.
• Lifecyle Ownership: Participate in scoping from the start, personally build high-leverage features, and own observability and on-call for what you ship.
• Agentic Development: Decompose features into agent-executable units, dispatch them to a fleet of coding agents running in parallel, and run multi-round agentic review before human review.
• 8+ years of professional software engineering experience, including 3+ years as the senior-most or lead engineer on a system with financial or operational consequences
• Demonstrated ownership of code review standards for a team, including holding contractors to those standards
• Current, demonstrable mastery of agent-driven software development in Cursor or a comparable agentic IDE
• Deep proficiency in C#/.NET, and strong proficiency in TypeScript and React
• Strong SQL Server skills: schema design, query performance, and data integrity under concurrent load
• Experience deploying and operating applications in AWS, including CI/CD and production observability
• Excellent written and verbal communication, with demonstrated effectiveness in ambiguous situations
• Must be able to pass a background screen
• You Own the Whole Thing: Not a seat on a 400-person engineering org — you're the senior-most engineer on a small team, with architecture and quality bar yours to set.
• Direct Access to the CTO: Report to and work daily with a hands-on, technical CTO. Decisions get made in a conversation, not a committee.

This is a full-time, on-site role, Monday through Friday during core business hours, with flexibility for release windows and production incidents. Travel is minimal.

If you think about software as a whole lifecycle — not just a series of pull requests — and you're ready to own architecture, quality, and technical direction for a platform that moves real money every month, we want to hear from you.
