GTM Engineer — SparqLabs

Type: Full-time · Remote · [timezone overlap: ]

Reports to: GTM Engineering Lead

About SparqLabs

SparqLabs is a done-for-you B2B outbound agency. We run cold email and LinkedIn campaigns end-to-end for B2B clients globally — ICP definition, list build, enrichment, dedicated sending infrastructure, human-written copy, reply handling, and booked meetings on the client's calendar.

We are not a software platform. We are a small operating team that builds and runs outbound systems by hand, with heavy automation underneath. Our differentiation is dedicated sending infrastructure, Clay-based enrichment, real copy written by humans, and infrastructure billed at cost with zero markup.

The Role

You own client accounts end-to-end. From the day a client signs to the day they renew, you are the person responsible for their campaign existing, running, and producing meetings.

This is not a ticket-taking role. You build the system, you launch it, you diagnose it when it underperforms, and you sit on the client call and explain what you're doing about it.

What You'll Own

Responsibilities

Onboarding

Run technical kickoff. Extract ICP, offer, and disqualifiers from the client. Translate a vague brief into a list spec and a campaign architecture.

List build

Source and segment target accounts and contacts using Clay, Sales Navigator, Apollo, Apify, and internal search tooling. Tight, defensible lists — not volume dumps.

Enrichment

Build Clay tables with waterfall enrichment, GPT columns, signal scoring, and personalization variables. Verify and bounce-clean before handoff.

Infrastructure

Provision domains and inboxes on dedicated EmailBison infrastructure.



Configure SPF/DKIM/DMARC, warmup schedules, rotation, and send windows. Own deliverability.

Launch QA Run every campaign through the pre-launch QA gate before it sends. Numeric pass/fail on list quality, variable fill rates, deliverability checks, and copy render. No campaign goes live without passing.

Monitoring & diagnosis

Watch open, reply, positive-reply, and booked-call rates daily. Diagnose underperformance correctly — distinguish audience-fit problems from deliverability problems from copy problems. Fix the actual cause.

Reply flow

Route replies into GHL with clean data. Support the reply desk with context, sequencing logic, and disposition rules.

Reporting

Produce weekly client reporting. Join client calls. Explain performance honestly, including when it's bad.

Internal systems

Build and maintain n8n automations, GHL workflows, and internal tooling that reduce manual work across all accounts.

Documentation

Write SOPs that end in numeric thresholds, not prose. If only you can run it, it isn't done.

What We're Looking For

Required

1. Clay, at a real level. Waterfall enrichment, HTTP API columns, conditional logic, GPT columns, table chaining. This is the hard gate — if you've only clicked around in Clay, this role isn't a fit yet.
2. Hands-on ownership of cold email infrastructure: domains,



DNS records, inbox provisioning, warmup, rotation, and deliverability triage.
3. Experience running sequencing platforms (Smartlead, Instantly, EmailBison, Lemlist, or equivalent) at multi-account scale.
4. Enrichment and data sourcing tooling: Apollo, Prospeo, Findymail, ZeroBounce, Sales Navigator, Apify or similar.
5. Automation platforms — n8n strongly preferred; Make or Zapier acceptable if you can show non-trivial builds.
6. Comfort with APIs, JSON, and light scripting (Python or JavaScript) for custom integrations and data transforms.
7. Ability to run a client call without a manager in the room.
8. Written English strong enough to send a client a performance explanation unedited.

Solid plus

- Prior agency-side outbound experience — you've run campaigns for someone else's business, not just your own.
- SQL or spreadsheet-level data analysis for funnel reporting.
- CRM configuration experience (GoHighLevel preferred).
- LinkedIn automation and multichannel sequencing.

Not required
- A B2B SaaS background. Agency and freelance operators are equally welcome.
- A degree.

How We Evaluate

Short screen, then a paid practical: we hand you a real ICP brief and you build the list, enrichment table, and campaign architecture. We assess your actual work, not your résumé. Final conversation with the founder.

What This Role Is Not

It is not a strategy role. You will be in Clay tables and DNS records daily.

It is not a copywriting role, though you will QA copy and own personalization variables.

It is not a role where someone hands you a spec. You write the spec.
