Role Overview

Founding product engineer role — the first engineering hire who will define the technical and cultural foundation of the company. Delegate builds AI coworkers — not chatbots — that own entire business processes end-to-end for enterprise teams. They call it the Agentic Process Engine, starting with sales (post-call briefs, follow-ups, pipeline hygiene, win wires, deal risk detection) and expanding into other operational functions.

~50/50 split between core agent infrastructure and end-user-facing product. Trajectory: writing code alongside founders today → leading a team and owning critical product surfaces in 2 years. Long-term vision: redefine work, where individuals manage agents performing most tasks.

Hard problems they're solving:

  • Designing agent systems that replace human workflows (not just assist)
  • Multi-step autonomous orchestration that holds state and adapts to context
  • Engineering around hallucination, state drift, over-triggering, and trust collapse at scale

Responsibilities

  • Build the core Agentic Process Engine — the system that runs business units, not individual tasks
  • Build the sales agent layer: post-call briefs, follow-ups, pipeline hygiene, win wires, proactive deal risk detection — all autonomous
  • Full stack: frontend, backend, orchestration infrastructure
  • Architecture for agent coordination across integrations, long-term memory, and reliable action-taking
  • Build the foundation of an engineering team they'll eventually hire and lead
  • Work with founders to shape product definition, interface with customers to identify pain points, and build repeatable solutions
  • Several design partnerships are materialising and require engineering support — this hire directly unblocks those

Ideal Background

Must-have:

  • 1–7 years of full-stack engineering experience (recently expanded from 3+ YOE to open up top of funnel)
  • Shipped real AI agent systems — tool use, multi-step reasoning, memory, autonomy (not just RAG/chatbots)
  • Early-stage startup experience — high ambiguity, no spec, no PM, made something out of nothing
  • Full-stack proficiency — team uses Python and React
  • Basic distributed systems knowledge (e.g., Temporal — not Temporal-specific)
  • General LLM understanding
  • Opinionated — strong views on system design, willing to push back
  • High agency, strong follow-through, output-driven
  • Undergrad in CS (top 100 school for new grads)
  • Based in SF or willing to relocate

Strongly preferred:

  • VC-backed, seed–Series B AI startup experience
  • Prior founder or founding engineer experience, OR rapid promotion track record
  • Replaced (not augmented) a business process with AI end-to-end
  • Deep integrations with GTM tools: Salesforce, Gong, Outreach, Slack, Google Workspace
  • Workflow orchestration or event-driven systems at scale
  • Thoughtful on human-in-the-loop design (when agents act vs. escalate vs. stop)
  • Strong network of engineers they'd bring along

Target companies: Perplexity AI, Scale AI, Cognition, Applied Compute, Google DeepMind, Notion, Vercel, Retool, Figma, Linear (plus 9 more)

Disqualifiers:

  • Pure frontend or pure backend (must be full-stack)
  • Large, slow-moving enterprise backgrounds (e.g., JP Morgan, SAP)
  • Managers without recent hands-on coding
  • Contract or short-term roles only — needs full-time startup experience
  • Candidates who can only articulate breadth, not depth — must show end-to-end system design in agent systems

Interview Process

  1. Founder interview — behavioural
  2. Founder interview — technical
  3. One-day paid work trial

Why Join

  • First engineering hire — defines architecture, culture, and category
  • Founders with proven enterprise scale — Scale AI $0→$100M in ~2-3 years
  • Tier-1 backing — Felicis-led, $8M seed, marquee unicorn design partners
  • Genuinely unsolved problem — agentic process automation, not chatbots
  • Founding equity — 0.5–5% with flexibility on base/equity mix (preference for higher equity + competitive base)
  • Competitive base — $230K–$300K
  • Direct founder access — every customer call, every product decision
  • Output over hours culture — not 996, but open discussions, rapid evolution, quick pivots, strong decision-making
