Company mission
Get back one hour every day. Begin your day with emails neatly organized, replies crafted to match your tone and crisp notes from every meeting.
Role
Who you are
- You’ve worked at an early stage company (<100 people) or been a founder yourself
- You have 4+ years experience and a expert level understanding of Typescript and React
- 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, answering data questions using SQL, and contributing to devops and CI/CD processes
- High interest in AI and the problem we’re using it to solve
- Urgency and intensity in your work
What the job involves
- We believe small, passionate teams outperform big, unfocused ones every time
- That's why we're highly selective about who joins us
- We're looking for people who bring intensity, creativity, and genuine care to their work
- You'll take on meaningful responsibilities from day one, with opportunities to grow faster than at most companies
- We trust our team with real ownership and autonomy because that's how the best work happens
- We only hire product engineers
- What that means is instead of just being given tickets to implement, you’ll be owning a whole product: shaping the roadmap by thinking from first principles, looking at usage data and speaking to customers, then architecting and implementing your ideas
- We use Typescript for all code
- We have a frontend app built with React, but the product is very backend heavy: it’s deployed on Google Cloud Platform using Cloud Functions, Firestore, Cloud Storage and PubSub
- We use Bigquery as our data warehouse, Looker to visualise it, and Sentry and Google Cloud Logging for monitoring
- We use Github Actions for CI/CD
Application process
- Matt, Cofounder and CTO, is the hiring manager
- Submit your CV (no need for a cover letter)
- We’ll review it
- An initial call with someone from the Fyxer AI team to review your experience and motivation for joining (20 mins)
- Live coding interview (45 minutes)
- Product case study (45 minutes)
- Meet more of the team over lunch (60 mins)

Our take
Built with the intention of turning the burden of email drafting into a business's competitive edge, Fyxer AI delivers AI executive assistants that can organise inboxes, draft emails in the tone of voice of each user, and write "better-than-human" meeting notes. Plugging directly into Gmail, Outlook, Slack, Teams, Google Meet and Zoom, its service is simple to use without the need to grasp additional software.
Fyxer is especially useful for industries that spend large amounts of time composing emails. Think real estate, consultants and recruiters, all saving time through the pure-play AI software of Fyxer and its open-source AI models and retrieval augmented generation. The company claims that its customers send 53% of the email drafts generated on its platform.
As more and more professionals turn to AI to save them time in their everyday tasks, Fyxer AI's secure and streamlined service is sure to gain more attention. Things certainly look to be going well, as in 2024, the company raised $500K in just three weeks from existing customers and their networks. It also rocketed from $1m ARR to $22m in just 10 months in 2025 - a sure-fire sign of the value users see in its offering

Company values
- What do we value? We're very intentional about adding new people. We believe a small team of exceptional people working hard at a problem they care about will always outperform a larger, more unfocused team. That means you'll need to bring an intensity to this role that might not be expected at other companies but it also means you'll be fast-tracked into roles with greater responsibilities far earlier.
