We are supported by capital from tier-1 venture capital, crossover, and endowment investors as well as the founders of the leading technology companies from the past decade.

The role

Own the architecture and delivery of our CRM and data-driven prospecting platform in a zero-to-one environment. You'll turn fuzzy problems into systems, standards, and processes that help BD, M&A, and portfolio teams move faster. This is an AI-first orchestration role: connect people, data, and systems to automate high-impact workflows and surface the right insight at the right moment.

What you'll do

Build the source of truth

• Design a unified "system of record + insight" that powers right-time outreach to top prospects
• Model entities (accounts, people, firms, signals) with identity resolution and data quality guardrails
• Ship self-serve reporting and dashboards with clear SLAs and definitions
  
  

Orchestrate AI-first workflows

• Automate multi-step GTM and BD processes across CRM, email, LinkedIn, and messaging
• Stand up LLM-powered agents for research, summarization, due-diligence prep, and follow-ups
• Implement RAG pipelines so teams see the right docs, notes, and signals at the right time
• Tune prompts, guardrails, and evaluation harnesses for accuracy, tone, and safety
  
  

Integrate data & systems

• Build and maintain two-way integrations between Salesforce and external data providers
• Connect APIs, webhooks, and event streams to keep data enriched, clean, and continuously updated
• Establish pragmatic privacy, reliability, and change-management practices
  
  

Prototype fast, scale what works

• Partner with BD and M&A leaders to identify high-friction workflows and measurable outcomes
• Deliver MVP automations quickly, instrument impact, and productionize winning pilots
• Define standards (runbooks, schemas, contracts, SLAs) that scale across the portfolio
  
  

Tech you'll touch

You'll span Salesforce and net-new applications:

• GTM workflows: LinkedIn, email, Slack, Clay
• App/dev: Python, TypeScript (Node.js, React), GraphQL/REST
• Data: Supabase/Postgres, eventing/webhooks, identity resolution
• AI: LLM APIs (OpenAI, Claude, etc.), LangChain/LlamaIndex, vector stores (e.g., Pinecone/Weaviate/pgvector), RAG patterns, prompt/guardrail/evals
• Orchestration & reliability: n8n, Temporal/Airflow (as needed), OpenTelemetry/Datadog
  
  

We have a greenfield stack—you'll have real input on the tools we choose to deliver business outcomes.

What you'll bring

• 8+ years in software engineering with meaningful ownership of CRM-centric platforms and/or revenue/ops systems; you thrive in ambiguity and create process where none exists
• Strong product sense for BD/M&A workflows; translate qualitative feedback into quantitative goals and SLAs that stick
• Deep integration experience (APIs, webhooks, auth), plus identity resolution and data governance fundamentals
• Hands-on with AI integration: calling LLMs, building RAG pipelines, prompt design, evaluation, and guardrails
• Clear, concise communication; you incorporate feedback from technical and non-technical partners into roadmaps that land on time
• Bonus: experience automating diligence (market maps, call notes, deal rooms), multi-channel orchestration (email/LinkedIn/Slack), and building portfolio-wide reusable components
