Senior Software Engineer

We are a fast-growing team on a mission to reimagine the analytical workflow and make data accessible to all.

The Count canvas combines the power of a data notebook with the collaborative workflow of digital whiteboards. We’re often referred to as the “Figma for data” because of the way Count transforms the way data teams work and communicate with the wider business through greater transparency and trust.

We launched in September 2022 and have seen the canvas concept explode with over 28k canvases created to date and some of Europe’s best startups such as Cleo, BeautyPie, TooGoodToGo and Omnipresent join us as customers.

We're looking for experienced software engineers who are interested in tackling deep technical challenges in data analytics. As an early hire, you’ll work closely with the founders on shaping the future direction for Count and be responsible for shipping entire features. Due to our small scale and flat structure, you’ll work autonomously on business critical projects, and collaborate with others throughout our team and user base.

Our tech stack includes TypeScript, Python, Node, WebAssembly, WebGL, Apache Arrow, DuckDB, Kubernetes and React.

For the best possible user experience, we have developed various technologies in-house, including a custom WebGL rendering engine, data visualization library, reactive SQL/Python notebook, and database query framework.

Some of the projects you could work on include:

• Accelerating rendering using quadtree tiling

• Extending the interactivity and customizability of visualizations

• Leveraging LLMs in data exploration

• Developing serverless frameworks for executing database queries at high concurrency

• Have at least 4 years of professional experience shipping features as a full-stack engineer

• Have experience working in a high-growth startup

• Love inventing solutions to complex technical challenges

• Are driven by a passion to create amazing user experiences

• Are comfortable working autonomously and taking responsibility for the delivery of large technical projects

• Are eager to learn from others and collaborative in helping others learn

• Want to shape the future of data analytics and visualization

1. An initial discussion (30-45 mins) for you to ask any questions you have about Count and for us to learn more about your experience and interests

2. A working session with our engineers (2-3 hours), where we'll dive into the stack and work with you through a technical challenge that we have faced recently

3. A final meeting with our founders (45-60 mins)

The working session and final meeting will take place either virtually or in London, depending on where you're based.

Count is a hybrid working company. Most of our team is based in the UK and we use our office in London as base to meet and collaborate regularly. However we believe great work can happen anywhere and we’re happy to consider candidates from elsewhere in Europe.

Our work is important to us, and we know we work best when we actively maintain a good work-life balance. We're backed by some of Europe's best investors allowing us to offer a competitive employment package. Some of the benefits of working at Count include:

• Competitive salary, pension and share options

• Flexible working hours

• 28 days of holiday (plus public holidays)

• Private health care

• Generous parental leave

• An annual working from home allowance and personal development budget

• Quarterly meetups with the team to relax and brainstorm, each time in a different city

We're committed to building a diverse team. Whatever your race, religion, colour, national origin, gender, sexual orientation, age, marital status or disability, we want to hear from you.
