About Poseidon

Poseidon is building the data infrastructure the next generation of AI will depend on. Foundation models are not limited by compute. They are bottlenecked by rare, high-quality, IP-safe data that actually improves performance: the long-tail, edge-case, multi-modal datasets that cannot be scraped or synthetically generated.

We are creating a data layer connecting AI companies with the datasets they need. Poseidon is the infrastructure that makes scalable, compliant, demand-driven data sourcing possible. Backed by a16z, we are early, moving fast, and looking for mission-driven teammates to shape this category.

Examples of the datasets we work with include conversational audio, complex video, domain-specific imagery, and other real-world data that enables models to perform reliably outside controlled environments.

The Role

We’re hiring a Strategy & Operations Manager to help us build and scale the internal engine of Poseidon—from product operations to GTM support, special projects, and strategic planning.

This is a high-impact, cross-functional role working directly with the founding team to bring clarity, structure, and executional rigor to a fast-moving organization. You’ll operate as a utility player across functions—tracking key initiatives, improving internal processes, and helping prioritize what matters most as we scale.

What You’ll Do

• Drive special projects across all parts of the organization (both internal and external), including product, BD, and ops to unlock near-term growth and long-term scalability

• Work closely with customers and suppliers to ensure success delivery of data projects

• Coordinate cross-functional launches (e.g., new product releases, partnership rollouts)

• Partner with founders to shape company priorities, OKRs, and strategic planning processes

• Build internal operating systems: project tracking, workflows, meeting cadences, reporting, dashboards

• Own research and analysis for competitive landscape, GTM strategy, and ecosystem mapping

• Identify operational gaps and implement solutions to streamline team velocity

• Support hiring, onboarding, and team development as we grow the org

• Serve as a key connector between internal teams and external stakeholders

What We’re Looking For

• 4+ years of experience in strategy, operations, product, management consulting, or founder/generalist roles

• Strong analytical and organizational skills — able to cut through noise and prioritize effectively

• Proven ability to drive cross-functional initiatives from idea through execution

• Excellent written and verbal communication skills; clarity and brevity are second nature

• Comfortable in ambiguous, fast-paced environments where you’re expected to build the process, not follow one

• Deep interest in AI, infrastructure, and early-stage company building

• Based in the U.S., ideally in the Bay Area or a major tech hub

Nice to Have

• Experience working in AI, Web3, or frontier tech startups

• Experience in project management and owning end to end delivery of customer projects

• Familiarity with company-building workflows (OKRs, board decks, fundraising support, etc.)

• Exposure to data infrastructure, marketplaces, or developer-facing products

Why Join Now?

This is a rare opportunity to get in at the ground level of an a16z-backed, Story-incubated startup tackling one of the hardest and most important problems in AI. You'll work directly with the founders, help define how Poseidon operates internally, and play a key role in scaling a category-defining company.
