Join the GTM Revolution at SalesCaptain — Where B2B Growth Happens
Since our beginnings in 2021, SalesCaptain has grown into a global force, working with fast-growing B2B brands, YC & Techstars startups, and Series B/C companies, helping them go to market through predictable, scalable outbound systems.
We're looking for a Senior GTM Engineer to own and evolve our outbound revenue infrastructure across client accounts.
This is a hands-on senior role sitting at the intersection of data, automation, AI, deliverability, intent signals, and outbound strategy. Beyond building systems yourself, you’ll help set technical standards, introduce new GTM technologies, and mentor other team members.
This is a full-time, remote role, working EU hours.
About the role
You’ll work closely with GTM Strategists, Campaign Managers, and other GTM Engineers to architect scalable outbound systems from ICP definition through campaign execution and reporting.
You’ll own complex Clay workflows, data infrastructure, intent and signal-based targeting, automation, and deliverability, while continuously testing new AI and GTM tools that can improve our results.
We’re looking for someone who can not only build great systems, but also lead technically, challenge existing processes, and help raise the standard of the wider team.
What you’ll do ✨
Architect end-to-end outbound systems, from ICP and TAM definition through enrichment, sequencing, CRM sync, and performance reporting
Build and optimize advanced Clay workflows, including enrichment waterfalls, Claygent, AI columns, conditional logic, and custom API integrations
Own and improve email deliverability infrastructure, including domains, inbox health, sending infrastructure, authentication, reputation, and scaling best practices
Design intent and signal-based outbound systems using signals such as job changes, funding, hiring activity, website intent, technology adoption, social activity, and other buying signals
Build automation workflows with n8n, Make, Zapier, APIs, and webhooks
Use AI and LLMs to improve prospect research, qualification, personalization, data processing, and campaign workflows
Continuously explore and test new AI and GTM technologies, identifying tools and approaches that can give SalesCaptain and our clients an advantage
Write lightweight Python or JavaScript and work directly with APIs when no-code tools aren’t enough
Partner with GTM Strategists to improve targeting, campaign architecture, and outbound performance
Establish best practices and documentation for GTM engineering workflows
Mentor junior and mid-level GTM Engineers, review workflows, troubleshoot complex problems, and help the team develop technically
Proactively identify inefficient processes and design better, more scalable solutions
Requirements
Who you are ❤️🔥
You should have:
3+ years of experience in GTM Engineering, RevOps, outbound operations, growth engineering, or a closely related role
Strong hands-on experience building outbound systems in a B2B SaaS, GTM agency, consultancy, or fast-moving technology environment
Advanced experience with Clay, including complex enrichment workflows, Claygent, AI columns, waterfalls, and APIs
Strong understanding of email deliverability, sending infrastructure, domain reputation, authentication, and inbox health
Experience designing campaigns around intent data and buying signals, rather than relying only on static prospect lists
Strong knowledge of the modern GTM tooling ecosystem and genuine curiosity around emerging AI and automation tools
Comfort working with APIs, webhooks, JSON, automation platforms, and basic Python or JavaScript
A strong commercial mindset — you understand ICPs, messaging, outbound performance, pipeline, and why targeting decisions matter
Strong problem-solving skills and the ability to design systems rather than simply execute predefined tasks
Experience mentoring, supporting, or reviewing the work of other team members
Excellent English communication skills (C1–C2), with the ability to explain technical concepts clearly to non-technical stakeholders
Experience working with Tech, SaaS, or B2B software companies
We’re also open to candidates coming from RevOps, growth engineering, Clay consulting, outbound operations, or highly technical SDR/BDR backgrounds who have transitioned into systems building.
What good looks like
You are successful in this role if:
GTM Strategists trust the systems and data you build without needing to recheck everything
Our outbound infrastructure remains scalable, reliable, and deliverability-safe
Intent signals help us identify better prospects and improve campaign timing
Clay and automation workflows are clean, efficient, documented, and cost-effective
You regularly introduce new AI, automation, and GTM approaches that improve how the team works
You identify problems before they become bottlenecks
Other GTM Engineers improve through your mentoring and technical guidance
You help the team move faster while maintaining a high standard of data and execution quality
This role is not for you if
You have never used Clay or similar GTM automation tools
Your outbound experience is limited to basic LinkedIn scraping or list building
You have little understanding of email deliverability
You prefer executing instructions rather than designing systems and proposing improvements
You are not interested in experimenting with new AI and GTM technologies
You are uncomfortable taking ownership of complex technical problems
You do not enjoy mentoring or sharing knowledge with other team members
Benefits
In addition to joining a fast-growing GTM team, we offer:
Remote work
Collaborative, friendly, and ambitious team
Paid vacation, days off, and sick leave
Team-building activities
Free books and Kindles to support your development
Specialized training and access to leading GTM tools
Opportunity to work with international B2B brands, startups, and scaleups
Hands-on exposure to emerging AI, automation, data, and GTM technologies
Significant autonomy to experiment, introduce new tools, and influence how our GTM infrastructure evolves
Opportunity to mentor others and play a key role in developing the GTM Engineering function
