Senior Clojure Engineer - Marketer: AI Powered Marketing

Marketer.com has nailed product-market fit with its AI-powered marketing platform for Shopify e-commerce stores. After successfully scaling across the US and EU, the team is growing fast and looking for a new top tier Clojure engineer to help keep the momentum going.

About the company

Marketer delivers an AI-powered, all-in-one marketing suite for e-commerce businesses that simplifies and streamlines all digital marketing needs in ways that were previously impossible. The SAAS platform is integrated with Shopify, the world’s largest e-commerce ecosystem, making it incredibly easy to adopt. The result is that e-commerce businesses can now accomplish tasks that used to require specialized agencies, independently, within minutes. Naturally, this has a significant impact on the ROAS.

A byproduct is a detailed, real-time overview of marketing and sales activities- something customers highly value. This stands in stark contrast to the Excel-sheet handovers stores are accustomed to from traditional marketing agencies.

Marketer was established in 2022 by the founders of Marketer Technologies, now one of Europe’s largest proptech companies. After two years of technical development, the commercial operations kicked off in full force in 2024. The company is now experiencing explosive growth and already boasts a solid ARR that is increasing by several hundred thousand per month.

The cap table includes Marketer Technologies, alongside the greatest chess player of all time, Magnus Carlsen, Johan Brand from Kahoot, and a handful of other prominent figures in tech and finance Who we’re looking for

You write Clojure like your own language - and you’re not afraid to architect backend systems that power real-world, high-scale usage. Marketer is growing fast, and we’re looking for someone who thinks functionally, ships pragmatically, and builds with clarity.

What You’ll Do

• Own and evolve key parts of Marketer’s backend, written in Clojure, built for scale and speed.
• Design and ship GraphQL APIs, integrating closely with Hasura and a Postgres-oriented architecture.
• Implement workflow orchestration using Temporal, coordinating async systems and events reliably.
• Work deeply with Postgres, optimizing queries and ensuring DB performance at scale.
• Build, maintain, and scale microservices that integrate seamlessly across our platform.
• Influence architecture, patterns, and tooling - your voice matters.

You Might Be a Fit If You…

• Are fluent in Clojure, especially for production backend systems - not just side projects.
• Have shipped and maintained GraphQL APIs
• Know your way around advanced PostgreSQL: triggers, generated columns, performance tuning, etc.
• Think functionally - immutability and pure functions are second nature.
• Have built and debugged distributed systems and workflows before, ideally using Temporal or similar orchestration tools.
• Are comfortable working solo, with full trust and high expectations.
• Bonus: You have experience with ClojureScript or Dart - full-stack flexibility is always welcome.

This Is Not for You If…

• You’ve never worked with Clojure in production.
• You need months to make architectural decisions - we move fast and fix forward.
• You avoid database-level thinking - we believe performance starts at the query.
• You want a team of 50+ engineers. We’re lean and hungry.

Who You’ll Work With

• Work closely with the founding team, especially the CTO and CEO.
• Collaborate with frontend (React/TS) and mobile (iOS) teams to ship full features end to end.
• Join a proven team building a product from $0 to $3M+ ARR in just 3 months.

What You Get

• Competitive salary depending on experience + stock options.
• MacBook and full equipment setup.
• Remote-first flexibility (or Oslo office if you want).
• Ownership. Freedom. Speed. And real users scaling with your code daily.
• A place to write Clojure that actually matters - not hobby scripts.
