• Own the future of HubSpot’s data stores • 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.

• Shape the technical direction for the data platforms • Drive architectural decisions • Write production code and lead complex initiatives • Build internal frameworks and APIs • Influence technical direction across teams

• Lead the technical strategy, architecture, and design for the collar • Translate customer and business needs into practical technical solutions • Ensure the collar meets requirements for performance, reliability, manufacturability, and cost • Work cross-functionally to support product discovery, experimentation, and field learning • Define and oversee validation, quality, and launch readiness activities • Identify and manage technical and production risks early • Support field issue investigations and drive continuous improvement • Track technical metrics and use data to guide engineering decisions

• Deliver key platform functionality. You'll work across Ably's realtime products including our low-level Pub/Sub APIs, our LiveObjects state synchronisation layer, and AI Transport, the messaging backbone purpose-built for AI agent communication, focussing on shipping new features, performance improvements, bug fixes and maintenance. • Work fluently with AI tooling. You'll use AI tools for planning, spike work, code generation, and documentation, while taking full ownership of correctness, architectural quality, and what actually ships. Fast iteration is expected; shortcuts in quality are not. • Solve hard distributed systems problems. You'll collaborate with a talented engineering team to work through genuinely interesting and challenging technical problems. • Stay driven by 'Developer First' principles. You'll work closely with other engineers to identify and address the most important problems developers face when building on Ably. • Push to see your work in customers' hands. You'll move with urgency to ship, because you care about the impact your work has on the developers and companies building on our platform.
