Job Summary

What are we building

The last major technological shift - the rise of the consumer internet - created LinkedIn as the networked winner in recruitment. The next great shift is here. AI is transforming how people and companies connect and it will redefine the global labour market.

At Jack & Jill we are building the company that leads this transformation.

Were 17 months old and have built a brilliant team of Europes best engineers operators and ex-founders. We just raised $40M Series A led by Air Street Capital with participation from Creandum and Madrona. Read more here the coming years every knowledge worker will have an AI agent managing their career and every company will have an AI agent helping them hire.

By connecting those agents were building a new infrastructure for the future of the labour market itself.

If that vision excites you come help us build it.

What is the role and who are we looking for

Were hiring a GTM Engineer to join our Jill Delivery team working alongside Ed Steele and Ed Kim. Youll build the machine that enables us to scale our GTM and customer base management to the next level.

Hundreds of companies have now set up a role via Jill. Our growth doesnt come from completely manual work - it comes from setting up scalable systems identifying signals including which accounts are at risk before they churn and which are ready to expand before they ask.

This is a 01 role and its genuinely technical. Youll ship agents own connections and integrations and build the systems end to end. Youll also sit close enough to customers to know which problems are worth solving.

What youll actually do:

  • Own GTM systems. Build systems for our commercial team that scale our impact further and provide greater visibility into whats actually happening across every account: usage health expansion signals churn risk and more.

  • Build complex scalable agents. We build with internal agents constantly and youll ship even more advanced agents into our existing workflows. This could include automating customer-facing delivery such as reactivation and expansion campaigns.

  • Turn signal into action. Uncover leading indicators that predict outcomes like expansion and churn and wire them into something that executes timely account-level interventions.

  • Bring strong commercial focus to everything you do. The ideal hire will frame everything in terms of commercial and customer outcomes: retention usage expansion roles and revenue per account and more.

  • Work deeply in the product. Collaborate with our engineers to A/B test features improve customer enablement in-product and constantly take on initiatives to improve our customer experience where possible.

Youll be a great fit if

You can build complex systems. Youve written or been exposed to production code or youre a self-taught builder who has shipped products and put them in the hands of users. Youre able to navigate a codebase and work with agents and APIs.

You think in systems. You see a manual process and instinctively work out what the scalable version looks like. Youre allergic to work that has to be redone every week.

Youre genuinely commercially minded. You care about value delivered to the end customer not perfect systems for their own sake. You focus ruthlessly on systems that move the needle towards improving business outcomes.

You use agents constantly. You never build without them you understand how to improve them and where they break and you have opinions about what should and shouldnt be automated.

Youve been exposed to hiring processes in some way. Ideally you understand what its like to be a hiring manager: the anxiety of a role sitting open too long and why speed and communication matter so much. That gives you genuine empathy for our customers.

Youre high agency. You find the highest-leverage problem and run at it hard. Youd rather ship something rough this week and iterate than spec the idealised version for next week.

The profile

Were open to exceptional people from a range of backgrounds but you likely fit one of these:

  • The GTM Operator Turned Technical: Youve spent time on the front lines leading sales calls and working in sales teams. Youve analytical have tinkered with agents and youve upskilled technically. Youre now leaning into building systems.

  • The Technical RevOps Profile: Youve worked in RevOps or growth and built the systems yourself rather than briefing someone else. Youve shipped scalable systems into production: automations integrations agents and more.

  • The Engineer Who Turned Commercial: You started as a software engineer and moved toward the customer - solutions engineering forward-deployed roles sales engineering or growth.

This role isnt for you if

You want a predictable 9-to-5. Were building fast and the work is intense. We respect life outside of work but we do what it takes to win.

You need a highly structured environment. Were in the ambiguous thrilling phase of 0-to-1. Youll be creating the structure not operating within it.

You want to jump straight into leading a team. This is primarily a hands-on IC role. The opportunity to grow is real but you need to earn it by doing first.
