Job description

Job Title: GTM Engineer
Department: Marketing & Growth
Reports to: Marketing Lead & Sales Lead
Location: Flexible / Remote

The Role

Codex is growing fast — new clients, new markets, new financial partners. The pipeline that feeds that growth runs on outbound, and outbound needs a dedicated owner.

As GTM Engineer, you'll build and scale the systems that get Codex in front of the right buyers: PSPs, remittance companies, fintechs, and institutional clients across globally. That means owning the full stack — sending infrastructure, lead sourcing and enrichment, ICP scoring, campaign operations — and delivering qualified meetings to a growing regional sales team.

This is a hands-on builder role that is performance and metrics-driven. You'll inherit a functioning outbound engine and your job is to scale it, sharpen it, and expand it. You’ll start off with being a heads-down operator: running campaigns, maintaining deliverability, iterating on sequences, and making sure what you're sending is converting. As volume grows, the role expands into broader demand generation ownership — new channels, ABM plays, and beyond.

You'll work closely with both the Marketing Lead and Sales Lead, and be a key part of how Codex scales its commercial reach across every region it operates in.

Responsibilities

Outbound Infrastructure & Deliverability

• Own the sending infrastructure end-to-end — domain and mailbox management, warmup, deliverability monitoring, and inbox placement across email and LinkedIn campaigns at scale

• Maintain and evolve the enrichment and orchestration stack: data sourcing, waterfall enrichment, ICP scoring, and routing logic

• Own the sequencer and multi-channel outreach stack (email, LinkedIn, and more) — campaign setup, A/B testing, reply handling, and ongoing optimisation

• Ensure no rep or outreach domain/account is double-contacted; build the deduplication and routing logic that keeps the system clean

Lead Generation & Enrichment Pipelines

• Build and run automated pipelines for lead sourcing, enrichment, and ICP qualification — using AI/LLM workflows, APIs, and automation platforms

• Develop signal- and intent-based prospecting workflows that surface high-fit accounts before they're being worked by competitors

• Research and maintain ICP definitions for each regional market

• Build personalisation at scale: automated company research, dynamic copy generation, and multi-variable sequence logic

Pipeline Delivery & Sales Alignment

• Own the CRM as the operational backbone of the sales and marketing function — maintaining data integrity, pipeline structure, lifecycle stages, and campaign attribution across the full funnel

• Own the qualified meeting target: track volumes, reply rates, meeting bookings, and pipeline attribution, and report on what's working and what isn't

• Build and maintain the lead routing and handoff logic between outbound systems and the regional sales reps — ensuring warm leads are passed cleanly with full context

• Create feedback loops with the sales team: what's converting, what's not, which ICPs are responding, and where copy or targeting needs to change

• Support reactivation campaigns for dormant accounts and inbound leads that haven't converted

Systems & Automation

• Own the integration layer between outbound platforms and our CRM — data hygiene, attribution, and campaign reporting

• Build automation workflows that reduce manual work across the marketing and sales function without sacrificing quality or personalisation

• Stay current on the GTM tooling landscape and proactively propose and test new tools, signals, and approaches

What We're Looking For

• 3 to 5 years of hands-on GTM engineering, growth, or outbound experience at a B2B fintech, payments company, or SaaS business — or as a GTM engineer at an outbound agency running campaigns across multiple B2B clients

• Built or meaningfully scaled an outbound motion with pipeline numbers you can defend: sending volumes, reply rates, meetings booked, pipeline influenced

• Daily hands-on with modern GTM stack: Enrichment/orchestration, email sequencers, LinkedIn automation, CRM, and deliverability at scale

• Strong automation and integration skills — you build the plumbing, not just the campaigns

• AI-native in how you work — LLMs and automation are your default operating mode, not a line on your CV

• Startup or agency background where you were the builder, not one seat in a large organisation

Nice to Have

• Background in fintech, payments, stablecoins, or crypto — ideally with outbound aimed at PSPs, remittance companies, neobanks, or institutional buyers

• Experience with signal- or intent-based prospecting workflows

• Familiarity with the cross-border payments ecosystem and the buying behaviour of the clients Codex sells to
