Customer Success Engineer

About Hedra

Hedra is a research and infrastructure lab advancing post-training and inference for multimodal and physical AI. Our ambition is to bring recursive self-improvement to models that learn from and interact with the real world.

We combine reinforcement learning research with GPU compute and optimized inference to help teams post-train, serve and continuously improve models they own.

We're backed by Index Ventures, a16z and Abstract Ventures. Our team works fully in person in San Francisco.

We're looking for people with startup experience who take ownership of their work and care deeply about the problems our customers need to solve. You'll help build the technology, products and business that turn this research into a lasting company.

The Role

As a Customer Success Engineer at Hedra, you'll own the technical relationship with our customers after they sign — getting developers and enterprise teams from first integration to production, and keeping them there. You're the hands-on technical partner closest to the customer's stack: debugging API calls, architecting integrations, tuning for latency and cost, and translating what customers hit in the field into product direction with our engineering team. You'll work side by side with our Account Executives, owning technical success while they own the commercial relationship.

Responsibilities

• Own the post-sales technical relationship for our API, agent, and inference customers, from onboarding and first integration through production deployment and expansion.

• Serve as the dedicated technical resource and advocate for developers and enterprise teams: debug API calls, review integration code, and guide customers to the optimal use of our models and platform.

• Architect and troubleshoot production deployments against real constraints, latency, throughput, cost per deployment, and reliability.

• Become one of the foremost technical experts on Hedra's platform, internally and for customers.

• Translate recurring customer pain points into concrete product proposals, working directly with engineering and product to ship fixes and features.

• Partner with Account Executives to drive adoption, surface expansion opportunities, and turn early pilots into scaled production usage.

• Build and maintain the runbooks, reference integrations, and docs that let customer success scale as we grow.

Qualifications

• 4+ years in a customer-facing technical role, customer success or forward-deployed engineering, solutions engineering, technical support engineering, or software engineering with direct customer exposure.

• Hands-on technical ability. You can write Python that works, read and debug an API integration, and produce working sample code. You don't need to be a full-time engineer, but you're comfortable in a customer's codebase.

• Experience with APIs, SDKs, and developer-facing products, and comfort explaining integration paths and deployment tradeoffs to technical buyers.

• A track record of getting customers to production and keeping them successful, ideally with usage-based or consumption pricing.

• Excellent communication skills and the ability to earn trust with developers and the leaders who sponsor them.

• Demonstrated curiosity about generative AI, world models, and the inference and infrastructure that make them usable.

• BS or BA in computer science, a related technical field, or equivalent hands-on experience.

Who You Are

• Self-motivated and independent: able to set ambitious (and yet accurate!) timelines and deliver on them.

• Low ego, high patience, proactive communication. Strong opinions, weakly held.

• Understand operational costs and overhead, short and long term, and how they show up in a customer's deployment economics.

• And most importantly, treat Hedra as your own and help shape the vision with us.

Benefits

• Competitive compensation and equity

• Healthcare (Silver PPO Medical, Vision, Dental)

• 401K

• Lunch and snacks at the office

We encourage you to apply even if you don't fully meet all the listed requirements; we value potential and diverse perspectives, and your unique skills could be a great asset to our team.
