Job Description

Product Engineer – New Product, First Owner Location: San Francisco, CA Compensation: $150,000 – $400,000 + 0.1%–1% Equity Type: Full-Time Visa Sponsorship: H-1B, O-1, OPT Priority: High --- About Company Client is a profitable, fast-growing, YC-backed company supported by top investors (GC, SV Angel, A Capital, Liquid 2, etc.). The company provides live company and people data via APIs and full dataset delivery, making hard-to-get data easy to use at scale. Their technology pipes in live data from over a dozen sources and delivers it instantly to customers, serving use cases such as:

  • Automatic pipeline building
  • Pipeline prioritization
  • Champion watching
  • Company and people triggers for sales and marketing automation
  • Investment deal sourcing Client’s goal is to index all important data on the web and deliver it to customers in an easy-to-use way. The company is launching a new consumer product to expand from <1% customer coverage to the full market. --- About the Role — Product Engineer (New Product, First Owner): The Company is seeking its first engineer dedicated to a new product line. This is a high-autonomy, high-ownership role for a builder, grinder, and founder-type engineer. You will own the product end-to-end from 01, including discovery, prototyping, building, shipping, and iterating. The product is a consumer-facing, self-serve layer on top of Client’s data infrastructure, enabling non-technical users (HR, Sales, Ops) to create AI agents from natural language prompts. --- Key Responsibilities:
  • Lead the 01 build of a new product on top of Client's APIs.
  • Build core algorithms for deterministic AI agents created from natural language.
  • Own product strategy and execution: user discovery, scoping, rapid prototyping, shipping, iteration, and metrics.
  • Collaborate closely with Sales and Customer Success to identify high-leverage workflows.
  • Build production-quality UX (fast, simple, correct).
  • Work with the Head of Engineering on architecture, reliability, and data/privacy guardrails. --- Requirements: - 5+ years shipping production-grade software.
  • Strong full-stack engineering fundamentals.
  • Proven 01 product experience.
  • Experience working with sales/GTM teams.
  • Ability to design and implement core algorithms, AI agent workflows, and natural language interfaces.
  • Willingness/eligibility to work in-person in San Francisco for prototyping days (visa sponsorship available).
  • Prior startup experience (Series A/B+ preferred). --- Preferred Qualifications (Green Flags):
  • Experience in growth engineering at top companies (Ramp, Brex, Rippling, Workato).
  • Founder or early-builder background, ideally in sales tooling, workflow automation, or data APIs.
  • Strong CS fundamentals — graduates from IIT/IIIT/DTU or top-tier equivalents.
  • Strong product mindset — ability to translate vague needs into shipped product.
  • Familiarity with sales data ecosystems (funding, jobs, company data).
  • Demonstrated ownership and tenure (2+ years in prior roles). --- Disqualifying Factors (Red Flags): - Job hopping (<2 years each role) without evidence of strong output.
  • No experience working with sales or customer-facing teams.
  • Extreme over-engineering tendencies.
  • Weak exposure to API-based tools, real-time data, or workflow systems.
  • Lack of grinder mentality — low resilience for high-effort build cycles. --- Interview Process: 1. 30-min video call with CEO 2. 45-min technical screen with Head of Engineering 3. 1-day onsite prototyping 4. Final CEO chat 5. Offer --- Ideal Companies From:
  • Brex
  • Ramp
  • Rippling
  • Plaid
  • Airtable
  • Numeral - (Also acceptable: strong growth-stage SaaS/data infra companies) --- Biggest Note:
  • Candidates who are top engineers, graduated from top universities, and have experience in big tech moving into startups are almost certain to be shortlisted.
  • Client is open to candidates with ex-quant backgrounds as well.
