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 spans several sub-functions — Integration Partners, Solution Partners, Cloud, Marketplace, and Startups — each of which owns a global strategy for their area. We're looking for a Partner Development Manager, EMEA to give those strategies a real presence in the region. This is a generalist, region-first role covering all partner types . Rather than owning a single function end-to-end, you'll work across all of them — combining new partner development with the activation of partnerships that already exist globally, wherever the region needs it most. You'll join an established global partnerships team, working day-to-day with our function leads and EMEA colleagues and reporting to the Head of Partnerships. You are the connection point between global partner strategy and the commercial, regulatory, and market realities of EMEA. Much of the work happens in person — building senior partner relationships, being present in the market, and capitalising on co-selling and co-marketing opportunities across the region. As regional partner volume grows, we expect the role to evolve and eventually specialise; you'll help shape what that looks like. What You'll Own Regional Partner Development Identify, prioritise, and close new partners across Integration, Solution, Cloud, Marketplace, and Startup motions where EMEA coverage does not yet exist — including smaller regional solution partners and resellers where they open up the market. Build and maintain a regional pipeline of prospective partners across all functions. Partner Activation & Enablement Localise and activate globally-sourced partnerships for the EMEA market, including regional enablement, co-sell

The Role We've been doing a lot of thinking as a team, and what we've landed on is that this person needs to be someone who takes ownership. Real ownership.

You're proactive by nature and complacency isn't something you settle for, and it’s not something we settle for either. You're constantly looking for ways to eliminate friction, automate the mundane, and elevate the bar for TechOps. People feel comfortable coming to you with problems because you're approachable and follow through. You're familiar with the needs of executives and senior staff, and you check in proactively when you know something critical is on the horizon like a board meeting, an earnings call, an internal conference or a big reveal rather than taking a back seat. What sets you apart is how much you care about the growth of the people around you. When you work through a tough ticket with a colleague, you make it a teaching moment. When you

Secure Every Identity, from AI to Human Identity is the key to unlocking the potential of AI. Okta secures AI by building the trusted, neutral infrastructure that enables organizations to safely embrace this new era.

You still write code. You also multiply the people around you, and you are the person product and engineering leadership call when an agent identity problem has no precedent. Responsibilities Own the reference architecture. Define the canonical agent identity, delegation, audit, and kill-switch patterns that Senior FDEs deploy across the portfolio, and keep them current as the standards and the product move. Lead the hardest accounts. Personally own the most strategic, regul
