Company mission
To offer executives a holistic service rather than a single employee and EA’s flexible and remote working.
Role
Who you are
- You’ve worked at an early stage tech company as a staff or lead engineer (<100 people), or been a founder
- 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
- Urgency and intensity in your work
What the job involves
- Reporting line - Matt Co-founder and CTO
- 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 for 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
- Our tech stack:
- Broadly, we use a fairly typical serverless Typescript stack. It’s not a requirement to have worked with every tool in this stack, but the more the better!
- Typescript for all production code
- Firestore as our production database
- Firebase Auth as our auth system
- Backend deployed on Firebase Functions, and making use of PubSub and Cloud Storage
- React frontend, using ShadCN for components, TailwindCSS for styling, React Query for state management
- Posthog for frontend analytics (events, sessions, feature flags, experiments)
- BigQuery as our data warehouse, with Metabase for data visualization. Production data and Posthog events both stream into it so data is in one place
- Sentry and Google Cloud Logging for monitoring
- Github Actions for CI/CD
Application process
- Submit your CV (no need for a cover letter)
- An initial call with someone from the Fyxer AI team to review your experience and motivation for joining (20-30mins)
- Product case study, remote (45 minutes)
- Live coding, remote (60 minutes)
- Meet team in office (60 minutes)

Our take
Fyxer AI delivers AI executive assistants that can organize 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.
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 - a sure-fire sign of the value users see in its offering.
