About the Role:
We’re looking for a Senior Software Engineer to join a newly forming team focused on rebuilding and modernizing our internal accounting platform. This is more than a feature delivery role — it’s an opportunity to shape a business-critical system, influence technical direction, and help define how the platform evolves for the future.
As part of a small, high-impact team, you’ll have strong ownership and autonomy from day one, combining hands-on engineering with technical leadership. You’ll work closely with Product Managers and stakeholders to break down a complex legacy system into scalable modern services using .NET, Vue.js, and modern architectural practices.
The new platform is built on a best-in-class accounting solution, which means the team’s focus shifts away from reinventing foundational accounting mechanics and toward what creates the most value: engineering deep, reliable integrations with Frontiers’ internal systems. You’ll be designing the connective tissue that makes the platform feel seamless across the organization — robust, maintainable, and built to last.
To build those integrations at speed and quality, we use spec-driven development powered by AI. Engineers author precise functional and technical specifications first; from those specs, AI tooling generates integration code as a starting point, which the team then reviews, refines, and owns. This workflow raises the bar for clarity and intentionality in software design, and it means you spend more time on architecture, edge cases, and correctness — and less time on boilerplate.
We’re investing in AI-driven engineering workflows and modern software delivery approaches, giving you the opportunity to work with emerging technologies while solving complex technical challenges at scale. If you’re excited by modernization projects, technical ownership, close collaboration, and a supportive environment that values work-life balance, we’d love to hear from you.
