About the Role

Apten is an omni-channel AI agent that automates sales and marketing conversations with millions of leads across SMS, voice, and email.

Apten communicates exactly like a human — dynamically switching between channels, personalizing every follow-up, and proactively using tools (CRMs, schedulers, lead systems) in-conversation.

We are profitable, well-funded, and growing fast.

We’re now scaling rapidly and looking for our second full stack software engineer to join us. You’ll work directly with the founding team to build core product experiences and infrastructure — from high-throughput message pipelines to voice bots, workflow builders, context management systems, AI-driven orchestration, and self-improvement systems.

This is an opportunity to own critical systems and shape the product and culture from the ground up.

What You’ll Do

Own and ship core features across the stack — from React frontends to AWS-based APIs, Lambdas, and microservices
Work directly with enterprises to build AI agents, and the data flywheels needed to give them proper context
Build scalable infra for messaging, AI inference, and automation at high volume
Experimental work - turn Apten into a self-improving, high-performance sales/marketing agent. 100% ownership, 0 bureaucracy

What We’re Looking For

Curiosity and drive to figure things out — whether debugging a scaling issue or building something completely new
Experience building and shipping production software (or equivalent skill) - personal projects are OK
Experience with TypeScript, React, and AWS (Lambda, ECS, DynamoDB, SQS, CDK, etc.)
Strong product sense — able to make pragmatic tradeoffs, prioritize for impact, and ship fast
Comfortable working across the stack (frontend → backend → infra)
Previous startup or early-stage experience a plus

---

Bonus Points

Experience working with LLMs
Experience with event-driven architectures and async workflows
Strong interest in AI-powered automation and conversational systems
