GTM Engineer, India

IMPORTANT: PLEASE READ BEFORE APPLYING

Signalmash operates a cloud communications platform that enables businesses to manage and deliver RCS, SMS, and MMS messaging through carrier and technology-provider integrations. The platform includes customer onboarding, messaging APIs, routing, compliance, vendor integrations, usage tracking, and billing.

As we scale our go-to-market motion, we are adding an India-based GTM Engineer to design, build, and operate the systems that power our outbound revenue engine.

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: instrumented, tested, and improved every week. You will work directly with US leadership, and what you build will be 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 a failing workflow at the data level, and proving — with numbers — that a campaign works before scaling it.

• Build and operate end-to-end outbound systems: ICP definition, list building, enrichment waterfalls, email verification, segmentation, and signal-based prospecting (hiring, funding, tech-stack, and intent signals).
• Own cold-email infrastructure: domains, mailboxes, warmup, SPF/DKIM/DMARC, sender rotation, inbox-placement monitoring, and send-volume discipline.
• Orchestrate multi-channel sequences across email and LinkedIn with personalization that comes from data, not templates.
• Keep the CRM the single source of truth: lead routing, deduplication, lifecycle stages, reply classification, meeting handoffs, and closed-loop reporting so every campaign's results feed the next one.
• Apply AI as a working tool, not a buzzword: LLM-driven research, personalization, scoring, and reply triage with human judgment gates; build agents and workflows with tools such as Claude Code where they beat manual work.
• Instrument everything: replies, meetings, and pipeline by segment and message; kill what does not work quickly and scale what does.
• Arm SDRs and leadership with clean lists, account briefs, and dashboards; document systems so they outlive any single tool.

• 2+ years building outbound/GTM systems hands-on (in-house or agency), with real artifacts you can walk through — workflows, campaigns, dashboards. We will ask to see them.
• Working proficiency across the modern GTM stack: Clay or equivalent; Apollo/ZoomInfo-class data sources; Smartlead/Instantly-class sequencers; n8n/Make/Zapier; and a CRM such as HubSpot.
• Demonstrated deliverability knowledge: you have set up domains and mailboxes, managed warmup, and kept campaigns out of spam at real volume.
• Verified use of AI in your work — not AI-curious: prompts, agents, enrichment, or scoring systems you personally built and can demonstrate.
• Comfort with APIs, webhooks, and light scripting (JavaScript or Python) to connect what no-code cannot.
• Data discipline: clean lists, deduplication, verified contacts, and accurate attribution.
• Strong written English — your messaging will be read by US buyers.
• Based in India with working-hours overlap into the US morning (approximately 6:30–11:30 PM IST as needed).

• Messaging or communications industry exposure: CPaaS, SMS/RCS/WhatsApp, contact center, VoIP/SIP, or telecom-adjacent SaaS.
• Prospecting into the US market.
• LinkedIn automation operated safely (HeyReach or similar) without burning accounts.
• Claude Code, MCP, or agent frameworks used in production workflows.
• Accountability for outcomes: you have owned a system end to end and been measured on meetings booked, not activity.

The position is based in India and may initially be remote. Signalmash is evaluating an engineering office in Kochi during 2026-2027. Candidates should be open to relocating to Kochi if an office is established.
