Description

Join to apply for the Senior Software Engineer, Platform role at Beacon Software

Beacon Software is a permanent capital holding company which acquires and grows essential businesses. We are a profitable series B+ firm that combines great technologists, operators and M&A professionals to accelerate the scale of the ambition of the dozens of business we own and operate. 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.
We are growing our team in Toronto, San Francisco, and New York. Apply below.
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
