Shape the technical direction for the data platforms that underpin HubSpot’s products, with a focus on the data stores themselves and the systems around them. - Drive architectural decisions across storage, access patterns, scaling models, tenancy, performance, and developer ergonomics. - Help define what the next generation of HubSpot’s database platform should look like, not just how to operate the current one. ### Be a deeply hands-on, high-leverage builder
Write production code regularly and lead complex initiatives from idea to rollout. - Build internal frameworks, APIs, and platform capabilities that make HubSpot’s data stores easier to adopt, extend, and evolve. - Turn ambiguous infrastructure problems into simple, scalable systems and clear technical direction. ### Lead platform architecture across multiple domains
Work across big data, SQL/Vitess, batch, stream processing, and search to establish consistent platform patterns where they matter and domain-specific depth where they do not. - Define reusable abstractions for data storage, ingestion, processing, and access that reduce fragmentation across the engineering organization. - Push for simplicity, clarity, and extensibility in systems that can easily become overly bespoke or operationally heavy. ### Influence across the broader engineering org
Partner with engineering and product leaders to align infrastructure direction with what HubSpot needs to build next. - Work horizontally across teams to guide technical tradeoffs, unblock difficult decisions, and raise the architectural bar for platform work. - Act as a multiplier through design reviews, technical mentoring, and principled decision-making on the most important systems in the space. ## What You Bring
Deep experience building and evolving large-scale distributed systems, especially storage systems, data infrastructure, or foundational backend platforms. - Strong architectural instincts with a bias toward simplicity, consistency, clear boundaries, and long-term platform leverage. - A track record of owning and delivering complex, cross-team technical initiatives with product-line or company-level impact. - Comfort working across multiple layers of the stack, from storage engines and data flows to APIs, internal frameworks, and developer experience. - A hands-on mindset. You lead by building, debugging, reviewing, and shipping, not by staying removed from the systems you influence. - The ability to move into unfamiliar technical territory quickly, form strong opinions grounded in first principles, and help teams make better long-term decisions. ## Why this role matters
HubSpot’s future depends on data platforms that are not only reliable, but also powerful building blocks for product innovation. The Principal Software Engineer in Data Infrastructure will help determine how those building blocks are designed, how they scale, and how engineers across HubSpot use them to create the next generation of our products. ---
