GTM Engineer

We build AI-first telecom infrastructure for voice agents. Low-latency, compliant voice rails designed for AI rather than retrofitted from human calling. Sarvam, Razorpay, Shiprocket, Bolna, Ringg AI, Branch and Fundamento build on us. We're scaling in India and opening the US this year.

You'll own the machinery between a voice AI builder discovering Vobiz and an account we can bill. You'll write code, wire systems together, automate what people are currently doing by hand, and own the numbers that come out the other end.

You'll work closely with marketing, sales, our DevRel, and the founders. You are the only person doing this job, which means full ownership, and the velocity is set by you.

• Own the path from first touch to billable account: form routing, deduplication, lead scoring, lifecycle stages, and self-serve signup to CRM sync.
• Build attribution that survives a multi-touch journey across two markets, and defend the number it produces.
• Generate target lists programmatically (Tracxn, GitHub activity, funding data, job postings, community membership) and score them for buying intent rather than buying static lists.
• Own outbound infrastructure end to end: domain warming, deliverability, sequencing, LLM-driven personalization at volume, and reply classification.
• Set up and run the email stack.
• Replace manual marketing work with code. If someone is doing it twice a week, it should be running without them.
• Instrument the self-serve funnel: signup, activation, first billable call.
• Build the dashboards leadership reads without needing you in the room.
• Connect website, CMS, CRM and product analytics into one system rather than four disconnected ones.
• Work with sales on routing, handoff and SLAs, so leads reach a human while they're still warm.
• Support paid and content with enrichment, audience data and performance feedback loops.
• Keep the data clean. Hygiene, deduplication, and keeping internal and test traffic out of reporting.

• There is one source of truth for qualified inbound, and nobody argues about the number in the meeting.
• Every lead that arrives is graded, routed and attributed without anyone touching a spreadsheet.
• Self-serve signups flow into lifecycle automatically, and activation rate is readable weekly rather than reconstructed quarterly.
• At least two email motions run unattended and keep producing.
• Target lists are generated and refreshed by systems you built, not bought and left to rot.
• Leadership can see where pipeline comes from without asking you to pull it.
• You can say which channels deserve next year's budget and show the working.
• The things you build keep running while you're on leave.

• 3–6 years across growth or marketing ops, or engineering that drifted into go-to-market.
• You write code. Python or TypeScript, comfortable with APIs, webhooks and a warehouse. This is not a technical-marketer-who-can-do-VLOOKUPs role.
• Working knowledge of HubSpot's API, not just its interface.
• You have built something that ran without you afterwards. This is the thing we'll dig into hardest.
• Comfortable using LLMs in a production pipeline, not just as a writing aid.
• Able to read a funnel and say which number is lying.
• Strong ownership. You go looking for the broken thing rather than waiting for it to be assigned.
• Comfortable moving fast across two markets at once.

Useful, not required: Clay, n8n or similar; developer tools or API-first B2B; running India and US funnels simultaneously; email deliverability; product analytics tooling.

Not required: Prior voice or telecom experience. Our DevRel will get you fluent on the product.

• A mission-led company that's growing fast, and still has a lot to build internally.
• High energy environment of a small team that's big on ownership and working together to make things happen.
• Direct access to founders, who almost always say yes to making bets and experimenting.
• You're the first person to own go-to-market as an engineering problem here. Nothing inherited, nothing to maintain, no existing playbook to work around.
• Real substance underneath the marketing. The market loves our product, the team works closely with client operators, we publish measured performance data and DevRel ships documentation, demo repos and integrations continuously.
• Real global exposure. India at scale, the US and other key markets from the ground up this year.
• Competitive compensation.
