Back-End Software Engineer (Go)

Quick Facts

• Role: Back-End Software Engineer (Go)

• Work model: Hybrid (minimum two days per week: Tuesdays and Thursdays)

• Location: NYC office in the Flatiron District

Description

Back-End engineers build the systems that power AI agents across the product suite, including scheduling, real-time infrastructure, collaboration, and enterprise controls. You will create services and infrastructure for agentic workflows such as session history, task scheduling, client-server protocols, and real-time pipelines connecting the AI layer to users. The role also focuses on scaling AI-powered features across consumer and enterprise customers.

Responsibilities

• Build and operate high-throughput production services for AI agent orchestration, connector integrations, and real-time data pipelines.

• Design and build core platform services: task schedulers, session and conversation history, client-server protocols, and APIs connecting the AI engine to product surfaces.

• Collaborate across the product suite (Go, Mail, Docs, Enterprise) based on team fit.

• Partner with ML/AI, Product, and Front-End engineers to ship AI-powered features end to end.

• Build and evolve infrastructure as code with an emphasis on high availability for consumer and enterprise.

• Contribute to a culture focused on documentation, testing, and reliability.

• Mentor and grow junior engineers.

Requirements

• 5+ years of back-end development with strong fundamentals in algorithms, data structures, and system design.

• Experience building, deploying, and debugging production systems at scale.

• Experience with AWS or another cloud platform (GCP, Azure).

• Comfort working with AI-powered systems, including LLM-based features and agentic workflows (AI backend service experience is a plus).

• Fluency with AI coding tools (Copilot, Cursor, Claude Code, etc.).

• Deep understanding of CI/CD and infrastructure as code.

• Plus: real-time systems, event-driven architectures, or high-throughput API design.

• Ability to work independently, manage priorities across multiple projects, and collaborate cross-functionally.

• Strong product instincts and ability to trade off speed vs reliability.

Benefits

• Excellent health care (medical, dental, vision, mental health, fertility benefits).

• Disability and life insurance options.

• 401(k) and RRSP matching.

• Paid parental leave.

• Paid time off: 20 days PTO, 12 paid holidays, two floating holidays, and flexible sick time.

• Generous stipends (caregiving, pet care, wellness, home office, etc.).

• Annual professional development budget and development opportunities.
