Founding Member of Technical Staff Developer Relations Engineering at Tensorzero

TensorZero is an open-source stack for industrial-grade LLM applications. It unifies an LLM gateway, observability, optimization, evaluations, and experimentation.See our GitHub repository to learn more.Our ultimate goal is to enable LLM applications to learn from real-world experience. The current offering is the first step towards that vision: it enables a feedback loop for optimizing LLM applications, turning production data into smarter, faster, and cheaper models.There are engineering teams building with TensorZero in all sorts of industries: healthcare, finance, recruiting, developer tools, consumer, etc.Here's a case study: Automating Code Changelogs at a Large Bank with LLMsOur technical team includes a former Rust compiler maintainer, machine learning researchers (Stanford, CMU, Oxford, Columbia) with thousands of citations, and the chief product officer of a decacorn startup.We’re backed by the same investors as leading open-source projects (e.g. ClickHouse, CockroachDB) and AI labs (e.g. OpenAI, Anthropic). We’re lucky to have years of runway, giving us the flexibility to fully focus on open source for now with an ambitious long-term vision.RoleWe're looking for a Founding Member of Technical Staff with a background in developer relations. This is the perfect role for a community-minded engineer. You'll work on technical content to drive adoption: demos, integrations & partnerships, documentation, videos, social media, and more. You're a "wartime growth hacker" who can think outside the box, with the technical background to build best-in-class software.Team & CultureWe’re a small technical team based in NYC (in person). As an early contributor, you’ll work closely with us and have a significant impact on the project’s future and vision.Viraj Mehta (Co-Founder & CTO) is an ML researcher with deep expertise in reinforcement learning, generative modeling, and LLMs. He received a PhD from CMU with an emphasis on data-efficient RL for nuclear fusion and LLMs, and previously worked in machine learning at KKR and a fintech startup. He holds a BS in math and an MS in computer science from Stanford.Gabriel Bianconi (Co-Founder & CEO) was the chief product officer at Ondo Finance ($20B+ valuation) and previously spent years consulting on machine learning for companies ranging from early-stage tech startups to some of the largest financial firms. He holds BS and MS degrees in computer science from Stanford.Aaron Hill (MTS) is a back-end engineer with deep expertise in Rust. He became one of the maintainers of the Rust compiler… while still in college. Later, he worked on back-end infrastructure at AWS and Svix. He’s also an active contributor to many notable open-source Rust projects (e.g. Ruffle).Andrew Jesson (MTS) is an ML researcher with deep expertise in Bayesian ML, causal inference, RL, and LLMs. He recently completed a postdoc at Columbia and previously received a PhD from Oxford, during which he interned at Meta. He has 3.3k+ citations and several first-author papers at NeurIPS and other top ML venues.Kincaid O’Neil (MTS) is a full-stack engineer who previously founded Gathers, a consumer social startup that curated intimate in-person experiences. Before that, he built open-source payments infrastructure for the Interledger Protocol and worked at Coil, Ripple, and Kava.█████ (incoming MTS) is an ML researcher with a background in causal inference, sequential decision making, uncertainty quantification, and algorithmic fairness (1.2k+ citations). Previously, he was an AI Research Lead at █████ and received a PhD in Statistics from CMU, during which he interned at █████ and █████._____ You?What We OfferCompetitive compensation — We believe that great talent deserves great compensation (salary, equity, benefits), even at an early-stage startup.Open-source contributions — The vast majority of your work will be open-source and public.Learning and growth opportunities — You’ll join with a background in design engineering but will have the opportunity (& be encouraged) to expand your skill set way beyond that (curious about ML?).Small, technical, in-person team — You’ll work alongside a 100% technical team and help shape our vision, culture, and engineering practices.Best-in-class investors — We’re lucky to be backed by leading funds like FirstMark (backed ClickHouse), Bessemer (backed Anthropic), Bedrock (backed OpenAI), and many angels. We have years of runway and a long-term mindset.We’re Looking ForStrong technical background — You’ve tackled hard technical problems. You’re comfortable driving large projects from inception to deployment.Community leader — You're excited to build a community of developers, teach them about TensorZero, and more.Technical writing & speaking — You're comfortable writing technical content, public speaking, organizing events, and more.Hungry for personal growth — There are no speed limits at TensorZero. You’re excited about learning and contributing across the stack.In-person in NYC — We work in-person five days a week in NYC. We work hard and obsess about the craft – but maintain and encourage a healthy lifestyle with a long-term mindset.You can find us on Github: https://github.com/tensorzero/tensorzero
