Job Description:

Discord communities generate millions of messages every month but community owners struggle to see what is happening inside them. Levellr provides the insight and tooling that turns that raw chat into clear actions and measurable revenue for names such as Fortnite, Fred again and the NFL. Much like Hootsuite, Sprinklr & Sprout built businesses to help companies with the shift into social media platforms a decade ago, we’re helping our customers with the shift into community platforms today.

Levellr is run by two co-founders, Tom (CEO) and Ben (CTO), who have been building communities for the last 15 years at companies big (YouTube, Interpublic Group) and small (MyCujoo). We’ve been working on the business since early 2021 and are backed by Crush Ventures and a portfolio of strategic and valuable angels.

What you will work on

• Build and release new features across our Nest.js, and SvelteKit codebase using TypeScript end to end.
• Design and tune Postgres and ClickHouse pipelines and schemas that can cope gracefully with millions of Discord messages every month.
• Build a beautiful, intuitive, LLM-powered user experience that helps power users extract key insights from our rich dataset.
• You’ll have ownership across the stack and contribute to both architecture and implementation.
• Share production support as part of a sensible on-call rotation with blameless reviews.

The tools we use:

What we are looking for

• Proven success working with large relational data sets including index design, partitioning and query optimisation.
• Confidence shaping loosely defined requirements with product and design and turning them into working software.
• Previous experience in a remote, start-up or high-growth environment where async communication is the norm.
• Ability to maintain a minimum five-hour overlap with the UK working day.

Nice to have: experience with ClickHouse or other columnar stores, large language model pipelines, or large-scale Discord bots.

How we work

• Remote-first culture with an allowance for co-working space or home-office kit.
• Small squads of two or three engineers plus product and design working in two-week sprint iterations.
• Linear for planning, Slack and Discord for chat, Loom for quick demos.
• We get stuff done. We have a bias for action and love creating value from nothing but our code and our conversations.
• We thrive in uncertainty. We listen to market feedback and iterate continuously to build products our customers love.
• We believe in ownership over oversight - everyone is trusted to do the right thing.
• Five weeks of annual leave plus UK public holidays.
• 5 weeks holiday allowance (plus public holidays)
• Co-working space access (Soho Works —> locations across London and US)
• Remote or Hybrid working with flexible working hours
• Stock option plan
• Home office budget once you pass 3 months probation
• Mental-health support through Spill and twice-yearly company meet-ups.

Interview Process:

• Initial screening call with one of our Talent Partners to get to know the candidate, sell the role and company, and assess fit. (30 mins)

Successful candidates will then receive a pre-recorded video intro from our CTO (Ben) and Engineering Manager (Miro) to provide more insight into the engineering team and culture.

• Technical pairing exercise - a 10-minute warm-up followed by a 30-45 minute pair programming session to assess coding ability and problem-solving skills. (60 mins)
• Technical/experience-based interview with Miro (Engineering Manager) and Ben (CTO) to dive deeper into your background and expertise, especially around database/data work. (60 mins)
• Final interview with our Chief of Staff (Grace) to assess cultural fit and provide an opportunity to further sell the role and company (45-60 mins)
• We aim to complete the entire process within two weeks and provide feedback after every stage
