GTM Engineer, India

The GTM Engineer will own the machinery of outbound: the systems that find the right companies, enrich and score them, reach them across email and LinkedIn with strong deliverability, and hand qualified conversations to our sales team with full context. This is an engineering role that serves sales, not a marketing role with tools. You will treat pipeline generation as a system that is instrumented, tested, and improved every week. You will work directly with US leadership, and what you build will become the operating system our SDRs run on. This is a hands-on builder position. The successful candidate must be comfortable wiring APIs and webhooks, debugging workflows at the data level, and proving with numbers that campaigns work before scaling them. • Build and operate end-to-end outbound systems including ICP definition, list building, enrichment waterfalls, email verification, segmentation, and signal-based prospecting. • Own cold-email infrastructure including domains, mailboxes, warmup, SPF, DKIM, DMARC, sender rotation, inbox placement monitoring, and send-volume discipline. • Orchestrate multi-channel outbound across email and LinkedIn using data-driven personalization. • Maintain CRM integrity through lead routing, deduplication, lifecycle management, reply classification, meeting handoffs, and reporting. • Apply AI to research, personalization, lead scoring, reply triage, and workflow automation using tools such as Claude Code. • Measure replies, meetings, and pipeline performance, quickly improving or replacing underperforming campaigns. • Deliver clean account lists, dashboards, documentation, and outbound systems that scale with the business.

• Competitive salary. • Build and own the GTM systems behind a rapidly growing CPaaS platform. • Work directly with US leadership and influence revenue operations. • Opportunity to work with modern AI tools, automation platforms, and outbound technologies. • Flexible remote-first work environment. • High ownership with the freedom to improve systems end to end. • Career growth as the engineering and revenue teams expand. • Potential opportunity to relocate to Kochi if a local engineering office is established.
