Automation Engineer / Junior Data Engineer — APIs, HubSpot, Monday.com, Make/Zapier

ABOUT CUSTOM CAPITAL Custom Capital is a growing U.S.-based financial services company. You'll sit under our Head of Data & Automation and be the hands that keep the company's systems talking to each other. THE ROLE You're an automation-first builder. Make and Zapier are in your toolkit, but your default is writing code directly against APIs — cleaner, cheaper, more reliable. You're also a power user of Claude Code (or similar agentic AI coding tools) and use it to ship faster than a traditional developer. You'll build and maintain integrations between our core systems (HubSpot, Monday.com, marketing and process-automation tools), handle reporting and database tasks, and work a steady stream of automation requests from every team. This is a growth seat: you'll be learning the full BigQuery/dbt stack from the Head of Data. WHAT YOU'LL OWN - Direct API integrations between business systems: REST APIs, webhooks, auth, retries, error handling — code first, Make/Zapier when it's genuinely the right tool - HubSpot administration: properties, workflows, data hygiene, integrations - Monday.com administration: boards, automations, integrations - Marketing and process automation builds and maintenance - Reporting support: SQL queries, dashboard updates, data pulls - Documentation for every integration and automation you ship MUST-HAVES - 2+ years building integrations and automations - Comfortable writing JavaScript or Python against third-party APIs — without middleware as a crutch - Power user of Claude Code or similar agentic AI coding tools — AI-assisted building is how you work, not a novelty - Real Make (Integromat) and/or Zapier experience, and good judgment about when NOT to use them - Working SQL - Hands-on with HubSpot and Monday.com, or a fast learner coming from similar platforms - Strong written English; organized and responsive - At least 4 hours of daily overlap with U.S. business hours NICE TO HAVE - BigQuery / dbt exposure (you'll grow toward the full data stack here) - n8n or other self-hosted automation tools - Marketing automation platforms (ActiveCampaign, Customer.io, HubSpot Marketing Hub) - Git and basic CI habits ENGAGEMENT DETAILS - Full-time (40 hrs/week), long-term, with a real growth path under the Head of Data - Hourly to start via Upwork, with intent to convert to a stable ongoing engagement - Fully remote HOW TO APPLY Start your proposal with the word BRIDGE, then describe one integration you built in code directly against an API (no Make/Zapier): which systems, what auth, and how you handled failures. Tell us how Claude Code or similar AI tooling fits into your workflow. Proposals without the keyword will not be reviewed.
