The Growth Engineering team is responsible for developing technology to grow the business faster across product, sales, and marketing via experimentation. Analytical skills, decision-making and creativity are important for each individual on this team.

What you’ll do:

  • Drive expansion and revenue growth by building systems that identify ICPs, decision-makers, and expansion opportunities within our user base
  • Automate GTM workflows across the buyer journey from account enrichment to personalised AI-powered outreach
  • Work across the stack to build data pipelines, enrichment engines, and outbound workflows that scale our land-and-expand strategy
  • Collaborate with Sales, Marketing, and Product to align experiments and systems with real GTM goals
  • Run data-driven experiments across user segments to uncover high-leverage opportunities and iterate quickly on what works
  • Build and maintain a reliable, scalable tech foundation for GTM automation, leveraging internal and 3rd-party APIs


What you need:

  • 3+ years of experience in a software or data engineering role, ideally in growth, RevOps, or GTM teams
  • Proficiency in Node.js, SQL & NoSQL, and working with APIs, automation tools, and data pipelines - but you'll use whatever tool is the best to get the work done.
  • Familiarity with tools like Clearbit, Apollo, Hightouch, Segment, or similar for enrichment, ETL, sync, and activation
  • Experience building scrappy tools, scripts, or internal apps to automate workflows and integrate systems
  • Strong problem-solving skills and the ability to turn ambiguous business goals into engineered solutions
  • Comfort working in a fast-paced, experiment-heavy environment where shipping fast matters


Nice to have:

  • A creative streak—you enjoy brainstorming bold, outside-the-box ideas, even if they seem wild at first.
  • Prior experience in a growth engineering, sales ops, or data-heavy GTM role in a SaaS or PLG company
  • Experience working with LLMs (e.g., OpenAI) to generate content or power user workflows
  • Experience with CRM (e.g., Salesforce/HubSpot), outbound tools (e.g., Outreach, Instantly), and lead scoring workflows
  • Understanding of data infrastructure and tooling like BigQuery, Hightouch, or reverse ETL platforms
  • A natural experimenter: You're excited by experimentation and automation — rapidly testing, iterating, and driving measurable business outcomes genuinely energise you
  • Startup experience: You've thrived in startups or rapidly scaling environments, enjoying the energy and occasional chaos inherent to growth-stage companies.


Values that are important to us:

  • You should be a great communicator and champion of our culture (Take a look at our culture document ! )
  • You're data-driven and customer-focused
  • Ownership Mentality: You don’t wait to be told what to do—you proactively spot problems, suggest improvements, and get things moving.
  • Passionate Ambition: You're genuinely driven to make our company the best in its class and take pride in contributing to our collective success.
  • You value fast & incremental engineering cycles
  • You maintain design excellence and minimise complexity
  • You measure your results & automate when possible
  • You get 10% better at something every week
  • You have an internal compass and take accountability & initiative
  • We value overcommunication, candid feedback and a results-driven culture


Perks and benefits:

  • Competitive compensation
  • Work remotely anywhere in your respective country
  • Ability to move laterally within a team and grow rapidly
  • Paid time off and flexible leave policy
  • No boss culture
  • Flexible working hours
  • LGBTQ+ friendly
