This is a high-impact individual contributor role. You will operate across the full stack of TypeScript, React, MongoDB, Express, and AWS (Lambda, SQS, Elastic Beanstalk, etc.). Your focus will be on improving system reliability, increasing deployment frequency, and building new customer-facing APIs and UIs.

You’ll be expected to step in quickly, understand how things work, clarify ambiguous requirements and begin making meaningful improvements with minimal direction.

• Write and maintain third party integrations
• Build bespoke integrations with our technology partners
• Approach every problem with a lens for privacy, security, and reliability
• Participate in on-call rotation

• Solid understanding of system design and API design
• Familiarity with event-driven systems (e.g. queues, async processing)
• Experience with databases (MongoDB, Postgres, etc.)
• Strong debugging skills and ability to stay calm under pressure
• Pragmatic mindset: able to balance speed, correctness, and long-term maintainability

Nice to Have:

• Deep experience with React architecture
• Experience with CI/CD and improving deployment workflows
• Experience with third-party integrations (especially in e-commerce / marketing ecosystems)
• Familiarity with Shopify ecosystem
• Experience migrating from MongoDB to Postgres
• Startup experience
• Experience building or maintaining design systems

How We Work:

• Small, senior team: you’ll work directly with the CTO daily
• High ownership, low bureaucracy
• “Clean as you go” mentality - we aim to get 1% better every day
• Pragmatic engineering culture: progress over perfection
• Heavy use of AI-assisted development tools (e.g., Claude, Codex)

Why Join Us:

• You’ll have direct, production impact on an application that has millions of end users
• Strong growth potential as the company scales
• Access to substantial AI tooling
• Per-developer, monthly R&D budget
• Competitive salary + equity
• Fun, cooperative work environment

Interview Process:

• Intro conversation with our CTO, Andreas Kavountzis (30 minutes)
