Founding Sales Engineer

About Featherless

Featherless.ai is building the world's most reliable open-model inference platform. Backed by AMD, Airbus Ventures, 500 Global, Kickstart Ventures, HF0 Residency, Panache Ventures, and Oakseed Ventures, we're a well-funded team of researchers and engineers on a mission to democratize AI through performance and accessibility. Our cloud provides instant access to 40,000+ open-source AI models and the research innovations powering next-generation efficiency, reliability, and model optimization.

We're hiring our first Sales Engineer to pair directly with our founding Account Executive in North America. You are the technical half of a two-person deal team: the AE owns the commercial motion, you own the technical win. Our buyers are developers, ML engineers, and CTOs, and they don't buy on slides. They buy when someone credible sits with them, looks at their workload, and shows them that open models on Featherless are faster, cheaper, and more reliable than what they're running today.

That's your job — hands on keyboard, in the customer's stack, from first technical call through production rollout. Because you're the first SE here, you'll build the function as you go: the demo environment, the POC playbook, the benchmark harness, the security answers, the migration guides. Every deal you win should make the next one easier to win. If you like being the person who can actually answer the hard question in the room — and want the technical foundation of a Series A GTM engine to be yours — this is for you.

• Partner with the founding AE as the named technical owner on every active opportunity in North America
• Run technical discovery: map each prospect's models, workloads, latency and throughput targets, spend, and constraints
• Design and drive POCs and benchmarks that prove Featherless against the incumbent — closed-model APIs, another inference provider, or self-managed GPUs
• Build the demo environment and reusable technical collateral that the whole GTM team sells with
• Own technical objection handling end-to-end: performance, reliability, cost modeling, security, and data handling
• Be the field's voice into product and engineering — you'll know what we're losing on before anyone else does

• Lead technical calls tailored to each buyer's stack: architecture reviews, live demos, and working code against their real use case
• Build migration paths off closed-model APIs and onto open weights — model selection, evaluation, prompt and output parity, cutover plan
• Run benchmarks and produce the throughput, latency, and cost-per-token analysis that anchors the business case the AE builds
• Scope and execute POCs with clear technical success criteria, then hold the customer and us to them
• Write the technical sections of proposals, RFP responses, and security questionnaires; keep a reusable answer library so we never write the same answer twice
• Support onboarding and first production workloads, then hand off cleanly and stay available for expansion
• Feed structured field input to product and engineering — feature gaps, model coverage requests, reliability issues, competitive intel
• Build and maintain the technical assets that scale the team: demo apps, notebooks, reference architectures, integration guides, internal enablement for BDRs and future AEs
• Represent Featherless technically at conferences, meetups, and developer events
• Keep POC and technical-stage detail current in Hub Spot so forecasting reflects technical reality, not optimism

• 3–6 years in pre-sales engineering, solutions architecture, or a forward-deployed / customer-facing engineering role — at a GPU cloud, inference provider, MLOps platform, AI/developer tooling company, or…
