OverviewStaff Product Engineer role at Fyxer AI. Base pay range is provided externally and will be discussed with your recruiter. The basics: your title will be Staff Product Engineer. This role pays above market rate with significant equity. Matt, Cofounder and CTO, is the hiring manager. We work Mon-Thu in our office in Chancery Lane, London, and Fri from anywhere.

What are we building?Walk around the average office and you''ll see people''s days taken up by emails, Slack and meetings instead of real work. People in client facing roles—think estate agents, insurance brokers, recruiters—feel this pain most acutely. Instead of meeting clients, they spend hours doing admin, following up, scheduling meetings, taking notes, answering questions, and sorting through inbox mess.

We’ve built an AI executive assistant that looks at all your emails, messages and meetings, and uses that knowledge to answer your email, schedule meetings, take next steps from meetings and organise your inbox.

How has it been going?Since launching in April 2024, we’ve gone from $0 to $16m in ARR and raised a Series B from top investors.

What do we value?Autonomy, agency, and ownership. Each of our Product Engineers owns one of Fyxer AI''s products. They own both the product strategy (we have no product managers and have no plans for that to change) and the execution of that strategy. They choose when to bring in qualitative data (customer interviews, surveys, etc.) and quantitative data, supported by our data engineering department. We''re intentional about adding new people, aiming for a small team of exceptional people who work hard on problems they care about. This means you may be fast tracked into more senior roles and responsibilities earlier.

What will I do?In short, own one of Fyxer AI''s most important products:

Decide on metrics for your product, and gain an intuitive understanding of its value by using it yourself and speaking to customers

Use quantitative data, customer insight, and product sense to build a strategy for your product area, and prioritise initiatives within that strategy

Execute your strategy by coding up your ideas

Manage and improve reliability in your product area, by monitoring logs, analysing support tickets and fixing bugs

A key area of responsibility will be mentoring and developing other product engineers, setting the product direction for a large area of the business, and setting the direction for the tooling the team uses internally to be productive.

What does our ideal hire look like?

You''ve worked at an early stage tech company as a staff or lead engineer ( You have an expert level understanding of Typescript and serverless architecture. If you don''t have these, you shouldn''t apply

You want to get involved in product work, rather than just being handed tickets. You''ll be expected to come up with features autonomously, by reading customer feedback and analysing usage data

You can function as a fullstack engineer, working on client and server side code, and answering data questions using SQL

High interest in AI and the problem we''re using it to solve
