Backend Engineer

We’re hiring Backend Engineers at SalesAgents AI.
We’re building multilingual AI voice agents that actually sound human. They qualify leads, handle objections, follow sales scripts, and hand warm prospects to human sales reps at the right moment-in English, Hinglish, Hindi, and other Indian languages.
We’re growing 2x month over month, and building beyond lead qualification: AI pitching and persuasion systems that use full conversation history across channels. Our customers are seeing measurable revenue lift-not demos or hype.
What you’ll work on
You’ll work on the backend systems that make our AI agents reliable in the real world:
Python backend services, scalable APIs, databases, and system design
Voice-agent and telephony systems that handle live customer conversations
Customer-support, configuration, campaign, and reporting services
Debugging and resolving production and client issues across services
Automations for campaign execution, reporting, deployments, and operations
New customer pilots, integrations, and AI sales-agent launches
Kubernetes, Docker, cloud infrastructure, and production deployments on AWS/GCP/Azure
Observability, reliability, and practical tools that help the team operate faster
This is not a narrow feature-development role. You’ll get to understand how the entire product works - from a customer’s campaign configuration to a live call, its outcome, and the report the customer receives.
What we’re looking for
Strong engineering fundamentals and the ability to learn anything fast
Strong Python/backend skills; experience with Django, FastAPI, or similar frameworks is valuable
Comfort with APIs, databases, distributed systems, Redis/queues, and debugging
Familiarity with Docker, Kubernetes, and production systems, or the eagerness to learn them quickly
People who take ownership-you’ll never hear “that’s not my job” here
An execution mindset: shipping, learning from production, and solving customer problems matter more than slide decks
Clear communication and the ability to work closely with product, operations, and customer-facing teams
Good to have
Experience with AWS,GCP, Azure, Kubernetes, or cloud-native systems
Experience with telephony, SIP, WebSockets, WebRTC, or voice applications
Familiarity with LLMs, speech-to-text, text-to-speech, or AI-agent systems
Experience building integrations, supporting customer deployments, or working in a startup
What’s in it for you
ESOPs and competitive compensation
A small, high-caliber team building a globally relevant AI product from India
Massive ownership, a steep learning curve, and direct impact on customer outcomes
The chance to build real systems used by businesses every day-not just maintain legacy code
