You'll work directly with our voice lead and collaborate tightly with our video teams and other senior members of the org. Concretely, you'll work on voice to voice models that produce text and voice simultaneously. Models that can reason, interrupt the user with back channeling and talk. Models that feel like you are having a natural conversation with, without the feeling of turn taking that is dominant in current speech to speech models. Your role would be

About Supabase Supabase is the Postgres development platform, built by developers for developers. We provide a complete backend solution including Database, Auth, Storage, Edge Functions, Realtime, and Vector Search. All services are deeply integrated and designed for growth. About the Role Supabase's Partnerships function is scaling fast - spanning Technology Partners, Solution Partners, Startups, and Cloud Partnerships. We're looking for a Partner Operations & Systems Lead to own the operational and technical backbone that lets this team move quickly and make decisions with good data. This is a senior, hands-on role. You'll design the systems, processes, and reporting that the whole partnerships org runs on - and, increasingly, you'll build the internal tools yourself. Supabase is investing heavily in AI-assisted development to move faster than a traditional ops build cycle allows, and this role is expected to be a leading example of that inside Partnerships. You'll report directly to the Head of Partnerships and sit alongside our regional and functional leads as a peer, with the mandate to build and enforce operational rigor across all teams. Beyond the infrastructure, we want someone who helps shape where Partnerships places its bets - not just the system that reports on them. What You'll Own Systems & Data Infrastructure Own the partner tech stack end-to-end - CRM partner objects, attribution tooling, and partner-facing portals. Design and maintain partner attribution models and the dashboards leadership uses to evaluate performance. Ensure data hygiene and consistency across partner records, deals, and touchpoints spanning all sub-functions. Process & Program Management Design and run partner onboarding, tiering, and certification programs. Own the RFC / DRI decision-making framework for the partnerships team, including how it's used and refined over time. Run deal-registration and "quarterback" account-ownership processes that keep internal teams

About Supabase Supabase is the Postgres development platform, built by developers for developers. We provide a complete backend solution including Database, Auth, Storage, Edge Functions, Realtime, and Vector Search. All services are deeply integrated and designed for growth. About the Role Supabase manages millions of Postgres instances and is growing. We have strong teams across observability, release engineering, and incident management — and we're concentrating our reliability efforts into a dedicated SRE practice that ties the discipline together across the platform. You'll be embedded within Service Operations, and your primary job is to make every engineering team more reliable — not by owning their infrastructure, but by establishing the practices, frameworks, and feedback loops that let them own reliability themselves. You'll work across the org: sometimes setting the standard, sometimes pair-programming a fix, sometimes helping a team define their error budget, sometimes telling them it's exhausted. This role is ideal for someone who has a strong vision for how SRE should work and thrives in async, fast-paced environments where influence matters more than authority. What You'll Own Partner with service teams to define meaningful SLIs and SLOs grounded in customer experience, and build the error budget policies that turn them into engineering decisions Own and evolve the Operational Readiness Review (ORR) process — conducting reviews for new services and major changes across observability, alerting, runbooks, capacity, and graceful degradation Strengthen the incident-to-improvement pipeline: connecting postmortem findings to operational readiness gaps, identifying repeat failure patterns, and driving systemic fixes Act as the reliability expert teams pull in for architecture reviews, failure mode analysis, dependency mapping, and resilience design Identify and quantify operational toil across the org, and build or advocate for automation that eliminates it
