Founding Go-to-Market Engineer

Job Description

At Sillage, we’re building the future of sales intelligence by turning raw market data into actionable buying signals. As a GTM Engineer, you’ll join our CTO’s team and play a central role in expanding the breadth and depth of our signal platform. We recently launched and are growing fast.

Your Mission Will Be To

• Develop and prototype new signals that help sales teams reach the right prospects at the right time.
• Work closely with the CTO to design, validate, and integrate these signals into our platform.
• Collaborate with early customers to test signals in real-world prospecting sessions, measure their impact and improve activation.
• Ensure smooth integration of new signals into our data pipeline and front-end experience.
• Act as a bridge between technical development and go-to-market experimentation, making sure what we build is truly useful to sales reps.

This role is highly cross-functional: you’ll be hands-on with data engineering and product experimentation, while staying close to customer use cases.

Preferred Experience

We’re looking for someone curious, scrappy, and excited to build in an early-stage startup environment. You might not tick every box, but here’s what would help you succeed:

• Experience in data engineering, data ops, or sales ops roles, ideally in a SaaS context.
• Ability to design and test data workflows (e.g., APIs, scraping, enrichment).
• Familiarity with sales processes, prospecting workflows, or CRM tools.
• Strong problem-solving mindset: you can go from an abstract “buying signal” idea to a prototype and then to production with the team.

Above all, we value curiosity, kindness, and a genuine interest in building the next French unicorn.

Recruitment Process

We Want To Keep The Process Simple And Human

• Intro call (30 min) – Meet the CEO to get to know each other and discuss your motivations.
• Technical conversation (45 min) – Deep dive with the CTO to discuss your experience and explore how you’d approach building signals.
• Practical case – A short exercise to brainstorm/develop a new potential signal and how you’d test it.
• Final chat – Meet the broader team, discuss culture fit, and answer any open questions.
