Job description

About this role

The Senior Backend Engineer will develop scalable APIs, connect internal and external systems with language models, work with databases and asynchronous processing systems, and help ensure production-critical AI workflows remain reliable and available. This is a hands-on senior engineering role for someone who can operate independently, make sound technical decisions, and ship reliable backend systems with minimal oversight. The ideal candidate combines strong backend engineering fundamentals with experience or strong interest in AI/LLM integrations, MCP, distributed systems, and production reliability. Fully Remote | 9:00 AM - 6:00 PM EST with 1 hour lunch break

Responsibilities

  • Design, build, and maintain backend systems supporting AI-powered products and workflows.
  • Develop integrations and connectors that allow AI agents to interact with internal and external services.
  • Build and maintain Model Context Protocol (MCP) tools and integrations.
  • Develop scalable REST APIs and backend services supporting automated workflows powered by language models.
  • Design reliable integrations between AI models, internal systems, and third-party services.
  • Work with relational and non-relational databases to support application and integration requirements.
  • Build and maintain asynchronous processing workflows using background jobs and queue systems such as Redis Queue, SQS, or similar technologies.
  • Design new backend capabilities rather than focusing solely on maintenance of existing systems.
  • Build technical infrastructure that enables AI agents to securely interact with business systems and data.
  • Integrate language models into production backend workflows.
  • Develop and maintain MCP servers, tools, and connectors for real-world AI applications.

Qualifications and requirements

  • 6+ years of professional backend engineering experience in production environments.
  • Strong experience designing, building, and maintaining backend services.
  • Strong experience with PHP is preferred.
  • Experience designing and integrating REST APIs.
  • Experience working with microservices architectures and distributed systems.
  • Experience with relational and non-relational databases.
  • Experience with background jobs, queues, and asynchronous processing systems.
  • Experience working independently on production-critical systems with minimal oversight.
  • Experience working in an early-stage startup environment or having founded or co-founded a venture.
  • Experience operating effectively in environments with ambiguity, changing priorities, and limited resources.
  • Strong backend software engineering and system-design fundamentals.
  • Strong understanding of REST APIs, service integrations, and distributed systems.
  • Experience with PHP or comparable backend technologies.
