Senior Software Engineer, Platform

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.

Key Responsibilities

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 Stack

• 
  

  Python, TypeScript (Node.js, React, Next.js), TailwindCSS, Postgres (Supabase), n8n, Prefect, Modal, Redis

What We’re Looking For

• 
  

  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

Our Values at Beacon Software

• Humility : We acknowledge that the path to getting to the right answer involves being wrong along the way. We have strong beliefs which are weakly held. We actively seek new ideas and believe we can learn from anyone at any time.

• Hunger : We play to win. We hold ourselves to high standards and will not be outworked. We take pride in having a deep sense of responsibility to ourselves, each other, our partners, and our customers. We believe to whom much is given much is expected.


• Horizon : We seek to build a generational software company. This will take decades. We manage our expectations and those of our partners to take advantage of the 8th wonder of the world - compounding growth.
