Senior Software Engineer, GTM

Retell AI

Retell AI is using first principles to reimagine the call center with cutting-edge voice AI.

Thousands of companies now utilize Retell's AI voice agents to handle sales, support, and logistics calls that once required large teams of human agents. Backed by Y Combinator, Alt Capital, and other leading investors, we have scaled to $60M ARR with a team of 40 people, up from $5M at the start of 2025.

Our vision for 2026 is to build a modern CX platform where entire contact centers are powered by AI. Instead of basic automation that needs constant human tuning, we're creating intelligent AI "workers" that can act as frontline agents, QA analysts, and managers — continuously executing, monitoring, and improving customer interactions.

We're growing quickly and looking for ambitious builders who want to tackle hard technical problems, move fast, and have real impact at one of the fastest-growing voice AI startups.

Let's build the future together.

About The Role

We're looking for a Senior Software Engineer, GTM who builds the internal systems that power our go-to-market engine. This is not a tools-admin role. You'll write production code, ship custom integrations, and build internal software that makes our GTM motion faster, smarter, and more reliable.

You'll own the full technical stack behind lead flow, enrichment, routing, automation, and reporting. You'll partner closely with sales, growth, and product to design and build scalable systems that directly impact pipeline and revenue.

Think of this as a software engineering role where the "product" is our GTM infrastructure.

Key Responsibilities

• Design, build, and maintain custom internal tools and services that power our GTM workflows (lead capture, enrichment, routing, outreach, reporting)
• Write production-quality code (Python, JavaScript/TypeScript, or SQL) to ship integrations between internal systems and external APIs
• Build and own data pipelines that ensure quality and consistency across the funnel, from top-of-funnel acquisition through closed-won
• Architect and improve our GTM outbound stack, connecting tools like Hubspot, enrichment APIs (Apollo, Clearbit), and automation layers -- writing custom code where off-the-shelf solutions fall short
• Create internal dashboards, scripts, and developer tools that improve sales team efficiency and visibility
• Continuously ship improvements that measurably impact pipeline generation and conversion

You Might Thrive If

• You have a software engineering background -- you've built and shipped real software, not just configured tools
• You have 3+ years of professional software engineering experience, with strong skills in Python, JavaScript/TypeScript, or similar languages
• You've built production integrations, internal tools, or data pipelines from scratch
• You understand the modern GTM stack and can identify where custom engineering beats off-the-shelf tooling
• You think beyond tooling -- you understand why data matters and how it influences sales outcomes
• You've shipped systems that materially changed how a revenue team operates
• You enjoy owning ambiguous problems and turning them into scalable, well-engineered solutions

Job Details
