Join a category-defining AI company building the future of SMB Growth.

At Atlas, we're making AI-driven phone and voice interactions feel as natural and responsive as talking to a human. Our mission is to help small and mid-sized businesses scale with "AI Revenue Agents" that launch campaigns in minutes and qualify every lead in 60 seconds.

Founded in 2024 by serial entrepreneurs with successful exits, we're a tight-knit team of 12 A-players who love solving hard problems and moving fast. If you're excited about building systems that power real-world AI interactions at scale, we want to talk.

About the Role

We're looking for a Backend Engineer (mid-level) to join our growing engineering team. You'll help design and build the infrastructure that powers our AI agents, voice pipelines, and integrations with external APIs and customer CRMs. This role is ideal for someone who thrives in a fast-paced startup, enjoys end-to-end ownership, and wants their work to directly impact customer growth.

Responsibilities

  • Design, build, and maintain backend services that support Atlas' AI voice and ad agents.
  • Work with cloud-native tools (serverless functions, queues, storage, etc.) to ensure scalable, reliable systems.
  • Develop and manage APIs that integrate Atlas with third-party CRMs, ad platforms, and communication tools.
  • Ensure data security, authentication, and compliance across all systems.
  • Collaborate with product, AI, and frontend teams to deliver features quickly and iteratively.
  • Monitor and optimize system performance for speed, reliability, and cost efficiency.

Experience

  • 4–7 years in backend development (Node.js, C#, or Python preferred).
  • Strong understanding of APIs, microservices, and event-driven architectures.
  • Hands-on experience with at least one major cloud platform (Azure preferred).
  • Database experience (SQL + NoSQL).
  • Comfortable working with queues, messaging systems, and distributed architectures.
  • Strong problem-solving skills and a bias toward action in dynamic environments.

Nice to Have

  • Experience with API gateways or API management (APIM).
  • Familiarity with authentication providers (Auth0).
  • Knowledge of CI/CD pipelines, DevOps practices, and monitoring tools.
  • Background in high-availability systems, call flows, or real-time communications.
  • Agile startup experience where you've shipped quickly and iterated fast.

Why Atlas

  • Be part of a small, elite team where your code directly impacts thousands of businesses.
  • Work on cutting-edge AI systems bridging digital ads, real-time voice, and CRM workflows.
  • Fast-moving environment where your contributions are visible and valued.
  • Culture of ownership, honesty, and customer obsession.
