Senior Professional Services Engineer

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.

• 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.

• 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/Type Script.
• 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 No
  
  SQL databases and the ability to explain technical decisions to non-technical stakeholders.

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.

Compensation is described as competitive and based on experience. The work offers variety across client problems, autonomy in choosing solutions, and close collaboration with product and engineering. People relocating to Spain may be eligible for the Beckham Law tax regime.
