Senior Professional Services Engineer

Role overview

Build and operate custom software solutions for client agencies with distinct processes and technical setups. This senior, coding-focused role takes work from a defined need through implementation and production support, then hands over documented solutions clients can maintain and extend. It combines integrations, automation, and AI-enabled workflows across multiple client environments whose priorities may change.

Responsibilities - Develop API integrations that connect client systems such as CRMs, messaging platforms, databases, and internal tools. - Build scripts, webhooks, and lightweight services; use workflow automation platforms when they are the most effective option. - Create and deploy AI agents and LLM-powered workflows using model APIs. - Release solutions to production and address failures, rate limits, retries, and unusual cases. - Keep multiple client configurations organized and provide clear documentation for handover. - Identify recurring needs, turn them into reusable components, and share findings with product and engineering teams.

Requirements - Six or more years writing backend code used in production, with senior-level ownership of integrations or comparable work. - Experience in professional services, forward-deployed, integration, or implementation engineering, or consulting for multiple clients. - Evidence of managing several differently configured client environments in parallel while adapting to changing requirements. - Strong backend skills in Python or JavaScript/TypeScript. - Solid understanding of REST APIs, webhooks, OAuth or API-key authentication, and data transformation. - Hands-on experience building with LLMs and AI agents, plus familiarity with AI coding tools. - Working knowledge of SQL and/or NoSQL databases and the ability to explain technical decisions to non-technical stakeholders.

Nice to have

Experience with n8n, Make, or Zapier; agent orchestration frameworks; cloud deployment on Railway, AWS, GCP, or Azure; Docker or serverless functions; and monitoring automated systems. A portfolio of integrations, automations, or agents is also useful.
