🚀 WE'RE HIRING AT SUPERSONIK
Software sales is changing fast. AI agents are moving beyond simple assistance and starting to run core go-to-market workflows: product demos, onboarding, enablement, sales training, and more.

At Supersonik, we’re building the infrastructure for this new agentic GTM stack. We’re backed by Andreessen Horowitz (a16z), and companies like Salesforce and HubSpot are already customers. We’re helping define a category we believe will become a core part of how companies grow.

THE MISSION
We're looking for a Founding GTM Engineer to build the AI-powered systems that run Supersonik’s go-to-market motion.
Your job is to build the machine that fills the pipeline with the right leads, researches and enriches them, scores them, routes them, and helps convert them with as little human hands-on-keyboard as possible. This is the system our GTM team will run on.

This role sits at the intersection of growth, engineering, and sales. You will build internal GTM infrastructure, connect tools and data sources, design automated workflows, and turn manual processes into systems that scale.

You will also be a power user of Supersonik itself. Part of the job is to use our own agents to demo, sell, onboard, and learn from customers, then turn those learnings into better workflows and better automation.

This is not a process-admin seat, and it is not a role where you fill the CRM by hand. This is a zero-to-one role with no existing playbook. You will write it, use Supersonik to run it, and build the agents that make it scale.

WHAT YOU'LL OWN
  • The AI-powered lead-gen machine. You design and build the system that sources, researches, enriches, scores, and routes leads, using LLMs, agents, and the modern GTM stack rather than manual effort or armies of SDRs.
  • An AI-first GTM toolchain. You constantly scan our go-to-market workflows for what can be handed to AI, and you ship those systems. The default answer is automation; humans handle the exceptions.
  • The pipeline structure. You design how leads are modeled, routed, and moved through stages so the right accounts reach the right people automatically.
  • Reporting infrastructure for the AI-native GTM stack. You build the data layer, views, dashboards, and MCP-style interfaces that surface pipeline health, conversion, account quality, and GTM performance to both the team and our AI agents. The goal is not just dashboards people read, but data our GTM motion can actually use.
  • Clean inputs for the people downstream. Forecasting, compensation, and deep tool integrations are owned by our Ops/Data lead. Your job is to feed those workflows the data they need, and to partner closely on the handoffs.

WHAT YOU MUST BRING
  • AI-first by default. You think in AI systems, not manual workflows. To you, every repetitive GTM process is a candidate for an agent. When you hit a task, your first question is “could an AI do this better than a human?”, and when the answer is yes, you go build it instead of staffing it. You already run your own work through AI and have replaced manual processes with agents and LLM-powered tooling.
  • A builder's instinct. You reach for automation by default and are fluent with the modern GTM and AI stack: agents and LLM tooling, workflow automation, enrichment, no-code/low-code platforms, light scripting, APIs, and SQL or equivalent data fluency. You've built systems, not just operated them.
  • Experience building automated lead-sourcing or outbound systems. You've stood up enrichment, scoring, or signal-based routing that delivered leads at volume, ideally with AI in the loop.
  • 4 to 6 years of experience, with at least 3 years in GTM engineering, Revenue Ops, Sales Ops, or a closely related operator role at a B2B SaaS or tech company.
  • CRM-literate and tooling-agnostic. You can design how data and leads flow through a CRM. We care that you can architect the system, not which logo is on it.
  • Proven zero-to-one ability. You can point to a project where the brief was "figure it out" with no prior playbook.
  • Comfortable in low-process, high-ambiguity environments; startup experience at pre-Series B or equivalent.
  • Cross-functional influence across Marketing, Sales, Ops, and Customer Success.
  • English at professional working level.

STRONG PLUSES
  • You've built a GTM motion from nothing. Ex-founders with a go-to-market background, or early GTM/growth hires who stood up the engine before there was a team, are exactly the profile we have in mind. You know how to get to a working system with no playbook and no one to delegate to.
  • You've built agentic workflows: chaining LLMs, tools, and data sources into systems that run end to end, with prompts and evals you actually maintain.
  • Experience designing routing, territories, or account segmentation.

THIS WILL NOT WORK IF YOU ARE
  • Someone who treats AI as a buzzword or a "someday" project rather than today's default tool.
  • Someone whose instinct is to solve volume problems by hiring or doing the work manually rather than building a system.
  • A profile whose entire career has been inside 100+ rep commercial orgs running someone else's playbook.
  • Looking for a finished stack to operate rather than a blank page to build on.

💵 COMPENSATION
We offer competitive compensation tailored to your level of experience.

📈 STOCK OPTIONS
Build the future of Supersonik and participate directly in the company's long-term upside.

🌱 WHY SUPERSONIK
• Small, elite team with startup and AI pedigree.
• Early exposure to C-level and AI strategy.
• Build the AI engine the whole GTM team runs on.
• Use our own AI agents to power your work.

We're based in Barcelona and New York and work in-person by design: tight collaboration, fast learning, and direct partnership with the founders, the AE team, and the broader GTM team.

If you want to be at the center of the agentic future of software, this is a unique opportunity.
