Job Description

This is a remote position.

As a Senior Software Engineer, you’ll focus primarily on backend development — designing, implementing, and optimizing APIs, data pipelines, and system integrations that play a crucial role in our platform. You’ll work closely with peers across engineering and product to deliver scalable, high-performance solutions that drive meaningful business outcomes.

What You'll Work On

  • Architect and implement systems that collect, store, and surface insights from large-scale creative and performance datasets.

  • Build robust APIs empowering clients, dashboards, and data consumers across the company.

  • Improve how marketers visualize and act on creative data through unified, reliable backend systems.

  • Diagnose and solve performance bottlenecks, infrastructure challenges, and integration issues.

  • Collaborate with a talented team to evolve architecture, tooling, and development processes as we grow.

Tech Environment

Our engineers work within a modern stack that includes TypeScript, Node.js, React, GraphQL, PostgreSQL, MongoDB, and Azure Cloud. You don’t need to be an expert in every tool — if you’ve mastered comparable technologies and love building resilient backend solutions, you’ll fit right in.



Requirements

You’ll Succeed Here If You

  • Have 6+ years of experience building production-grade systems or APIs at scale.

  • Are fluent in at least one strongly typed modern language (TypeScript, Go, or similar).

  • Have hands-on experience with queuing systems, data streaming, or asynchronous processing.

  • Understand how to model, aggregate, and move data intelligently (bonus if you’ve worked with ETL or analytics-heavy systems).

  • Communicate clearly and confidently with both technical and non-technical stakeholders.

  • Thrive in ambiguity — you enjoy shaping problems rather than waiting for them to be defined.

  • Care about delivering real business impact, optimizing for speed and iteration over theory.



Benefits

Why You’ll Love Working Here

  • Real ownership and autonomy: Your code makes a visible impact from day one.

  • Strong compensation: Competitive salary, meaningful equity, great benefits, generous PTO, and a dedicated wellness budget.

  • Remote-first culture: Work wherever you’re most effective. We have hubs across North America and Europe for those who enjoy occasional in-person collaboration.

  • Momentum and scale: Our product adoption is accelerating fast — and you’ll help define what the next generation of creative intelligence looks like.

  • Collaborative team: We value curiosity, low ego, and building together. The best idea wins — no matter who proposes it.
