Helicone: The Complete LLMOps Stack

We provide comprehensive observability for LLM applications alongside our lightweight, Rust-based AI Gateway that enables intelligent routing across 100+ language models. Hundreds of AI teams trust us to build, monitor, and optimize their AI workflows at scale.

Over the past six months, we've doubled our revenue and are assembling a world-class DevRel team to distribute the future of AI tooling.

We're a small, driven team in San Francisco focused on autonomy, speed, and results through collaboration rather than bureaucracy.

The Role: Developer Advocate

You'll be a founding member of our Developer Relations team, working directly with Cole (Co-founder & Head of Growth) and Juliette (DevRel Engineer) to drive adoption of both our observability platform and AI Gateway.

Technical Content & Education:

• Create compelling technical content (blog posts, tutorials, video content) showcasing AI observability best practices and Gateway implementation patterns
• Own SEO strategy and content marketing to increase developer discovery
• Develop integration guides, code examples, and sample applications
• Improve docs and onboarding based on community feedback

Community & Developer Experience:

• Build and nurture our developer community through Discord, forums, and social channels
• Gather feedback from engineers and translate it into actionable product roadmap input
• Host meetups, workshops, and speak at conferences
• Provide technical support to developers implementing our platform

Growth & Adoption:

• Run experiments across growth channels and launch creative campaigns
• Partner with AI teams, YC founders, and developer communities
• Collaborate with our design team on developer-facing materials

This role offers the opportunity to define our developer relations function, mentor future team members, and grow alongside a rapidly expanding company in the AI infrastructure space.

We Want Someone Who

Has Technical Ability: You can code well enough to build LLM demos and integration examples. While you don't need to be a senior engineer, you should be comfortable with Python/TypeScript, APIs, and working with LLMs.

Thinks like a founder: You identify opportunities, test ideas quickly, and own outcomes.

Creates exceptional content: You can write clearly, create engaging video content, and explain complex AI concepts without jargon. You understand what makes technical content go viral.

Obsesses over developer experience: You talk to users, identify friction points, and advocate for their needs.

Can represent Helicone: Whether at events or on socials, you help build trust in our brand and vision for AI infrastructure.

Nice to have (not required):

• Experience building LLM applications or working with AI observability tools
• Background in early-stage startups or high-growth developer tools
• Track record of creating viral technical content or leading successful developer campaigns

Why You'll Love It Here

Your ideas matter: No "this is how we've always done it" energy

Autonomy: Lead projects with support rather than oversight

World-class team: We're building an absolutely exceptional DevRel team - brilliant engineers and marketers passionate about developer experience

Radical transparency: We share metrics, mistakes, and hard questions openly

Team: SF-based collaboration 4-5 days/week with people who care deeply but don't take themselves too seriously

Fun: Offsites (Redwoods hikes, bowling, tech museums), weekly team lunches, and zero pointless meetings
