Cekura (YC F24) is one of the fastest-growing companies in its batch, with strong revenue traction. We're well-funded, backed by premier investors, and have years of runway.

We're building the reliability layer for Conversational Agents. Teams use Cekura to simulate and monitor their AI agents end-to-end - measuring latency, barge-in, instruction-following, regressions, and more across phone, chat, SMS, and web. Customers love the product - and we're just getting started.

You're joining at an inflection point. As Product Engineer, you'll build the playbooks, processes, and relationships that define how Cekura partners with technical customers for long-term success. You'll be both strategist and hands-on operator.

• Be a trusted technical advisor: Guide customers on integrating Cekura into CI/CD and production stacks (APIs, webhooks, auth, SIP/Twilio flows, STT/TTS, LLM configs).
• Drive product feedback: Partner with Engineering; submit crisp RFCs backed by usage data to influence the roadmap.
• Proactive account management: Monitor health, predict risk, and execute save/expansion plays based on telemetry.
• Foundational leadership: Help hire and mentor the future Product & FDE team; set standards as we scale.

• Customer-obsessed: You care deeply about measurable outcomes and long-term partnerships.
• Technical pedigree (dev-tool savvy): You can read API docs, inspect payloads, and reason about systems. You've used Postman/cURL; you're comfortable with logs/dashboards and basic scripting.
• Clear communicator: You distill complex concepts for execs and engineers alike.
• Builder's mindset: You thrive in zero-to-one, create structure from ambiguity, and bias to action.
• Analytical: You ground decisions in data - usage, adoption, performance, and business impact.

• 2 years in a technical role at a developer-focused or infra/SaaS company.
• Comfort with APIs, webhooks, basic SQL, and one of Python/JS (to prototype, parse logs, or write examples).

• Ex-founder or Early/founding FDE or first FDE hire experience (you built the playbook).
• Familiarity with at least one of: LLM/AI agent tooling, observability/testing.

• You need rigid processes or heavy structure.
• You prefer pure relationship management without technical depth.
• You don't enjoy fast-paced, in-person startup environments (we're in SF, 6 days/week).

• Responsibility & scope: Shape the foundation of our Product org.
• Exceptional team: Work directly with founders and a highly technical, product-driven group.
• Impact: Improve the reliability of AI agents used by real customers every day.
• Upside: Competitive compensation, meaningful equity, and rapid growth.
• Benefits: Medical/dental/vision, team lunches and dinner!
