We work with the majority of the Top 500 firms in the country. We're replacing 40-year-old tax engines and brittle integrations with software accounting firms can actually trust, and we have rare product-market fit in an industry that's about to change permanently. We're hiring a Director of Platform Engineering to lead the foundation it all runs on. THE ROLE Platform owns the parts of Aiwyn that everything else is built on: our build and cloud infrastructure, our core IP data ingestion and normalization pipeline, our tax engine, our implementations engineering, and the productivity group elevating how the whole company works in the AI era. You'll lead five teams and roughly thirty engineers today, with engineering managers on each team and a peer product leader you'll partner with closely. Headcount will grow. This is a platform role with a lot of product work in it. The ingestion and normalization pipeline and our tax engine are core IP, and the work to make them best in class is going to come straight from your org. You won't just be enabling other people's products. You'll be building some of the most important ones at Aiwyn. WHAT THE PLATFORM DELIVERS When this role is going well, the rest of Aiwyn feels it. Specifically: - Product teams ship on top of platform without thinking about it. Our internal APIs, primitives, and golden paths are well defined enough that other engineers reach for them by default. They don't fight infrastructure, they don't reinvent integrations, and they don't get blocked waiting on us. - Our ingestion pipeline and tax engine are best in class. Firms trust us with the data and calculations their entire practice depends on. The platform team is delivering accuracy, performance, and breadth that legacy providers can't match. - Implementations land cleanly. New customers get to value fast. Engineering, product, and the customer team have a shared view of what's happening, and the same bug doesn't surface twice. - Production is boring. Deploys are daily, incidents get diagnosed at the root, and the team takes infrastructure, change management, observability, and on-call seriously enough that surprises are rare. - The whole company moves faster because of how this team works. The productivity team is shipping leverage that compounds across engineering, product, and operations. AI isn't a side initiative, it's the default way work happens. - The team is legible. Anyone in the company can see what platform is working on, why, and how it's going. DAY TO DAY - Lead the leaders. Coach and develop EMs across infrastructure, foundations, tax engine, implementations, and productivity. Hire when the bar requires it, performance manage when it doesn't, and build a leadership team that can scale. - Own the operating model. Define the rhythms, metrics, and standards that make the org legible and accountable, including cycle planning, change management, design review, incident response, and on-call quality. - Set technical direction. Partner with your engineers, EMs, and anyone else with strong opinions on the multi-year evolution of the tax engine, the ingestion and normalization pipeline, and our core infrastructure on GCP. - Hold the bar on operational excellence. Get us to daily deploys. Push incident response toward root cause. Build the metrics and forums that make execution legible and force the right conversations. - Partner across the company. Work shoulder to shoulder with your peer product leader on platform, with the product engineering org, with support, and with GTM. Earn trust by execution and by making other
