Cekura is a Y Combinator–backed startup redefining AI voice agent reliability. Founded by IIT Bombay alumni with research credentials from ETH Zurich and proven success in high-stakes trading, our team built Cekura to solve the cumbersome, error-prone nature of manual voice agent testing.

We automate the testing and observability of AI voice agents by simulating thousands of realistic, real-world conversational scenarios—from ordering food and booking appointments to conducting interviews. Our platform leverages custom and AI-generated datasets, detailed workflows, and dynamic persona simulations to uncover edge cases and deliver actionable insights. Real-time monitoring, comprehensive logs, and instant alerting ensure that every call is optimized and production-ready.

In a market rapidly expanding with thousands of voice agents, Cekura stands out by guaranteeing dependable performance, reducing time-to-market, and minimizing costly production errors. We empower teams to demonstrate reliability before deployment, making it easier to build trust with clients and users.

About Us

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.

About the Role

You’re joining at an inflection point. As Founding Customer Success Manager, 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 - equally comfortable running an executive QBR and popping open logs to help debug an integration.

What You’ll Do

• Own onboarding end-to-end: Seamless handoffs from Sales; define success criteria, timelines, and milestones; instrument adoption and time-to-value.
• 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).
• Build scalable systems: Create repeatable runbooks, health scores, QBR templates, and playbooks for expansion/renewal.
• Drive product feedback: Partner with Engineering & Product; 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.
• Hands-on problem solving: Reproduce issues, triage with engineering, and close the loop with clear comms.
• Executive storytelling: Quantify ROI (quality, reliability, speed); craft references and case studies.
• Foundational leadership: Help hire and mentor the future CS team; set standards as we scale.

About You

• 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.

Minimum Qualifications

• 2 years in Customer Success, Solutions Engineering, Sales Engineering, or Technical Account Management at a developer-focused or infra/SaaS company.
• Proven ownership of onboarding → renewal/expansion for technical accounts.
• Comfort with APIs, webhooks, basic SQL, and one of Python/JS (to prototype, parse logs, or write examples).

Nice to Have

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

This Might Not Be for You If

• 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).
