Senior Full-Stack Engineer

About the Position

We’re hiring our first engineer in the New York office. You’ll spearhead development of LLM‑powered products at the forefront of marketing and advertising technologies. You’ll own delivery from idea to production and set the tone for engineering craft across our NY–EU offices.

You’ll partner closely with product and design to turn ambiguous problem spaces into crisp, user‑facing experiences that perform, scale, and are easy to iterate on.

You’ll also help define our cross‑Atlantic collaboration rhythms: communication standards, documentation practices, and ceremonies that keep New York and Europe aligned.

This role presents an exciting opportunity to shape the future of AI‑driven technologies and make meaningful contributions to real‑world applications.

The role is based in New York City, and we are flexible about remote work in the east coast timezone.

What You’ll Be Doing

• Lead the architectural design and implementation of scalable, secure web applications.
• Ensure the technical feasibility of UI/UX designs and optimize applications for speed and scalability.
• Conduct code reviews and ensure adherence to best practices and coding standards.
• Collaborate across offices: drive clear communication with engineering in Europe (RFCs, decision records, async updates). Cultivate a culture of collaboration and innovation.
• Adapt quickly: navigate shifting priorities with a bias to action; make reversible decisions, learn fast from user feedback, and iterate.
• Stay current with emerging technologies and industry trends, and evaluate their potential impact on the business.

Qualifications

• 5+ years of experience in full‑stack web development.
• Proven experience with TypeScript and React, and building full‑stack applications with these technologies.
• Familiarity with the latest advancements in the React ecosystem.
• Demonstrated ownership of end‑to‑end delivery (from prototype to production), using modern CI/CD, feature flags, and telemetry to ship safely at speed.
• Product‑minded: you care about UX quality, customer experience, and software quality.
• Strong analytical and problem‑solving abilities.
• Startup‑ready: flexible, comfortable with ambiguity and constant change; proactive about process, documentation, and reliability without over‑engineering.
• Excellent communication skills, with the ability to explain complex technical concepts to non‑technical stakeholders. Demonstrated leadership experience, with the ability to guide and inspire a team.

What We Offer

• A dynamic role at the forefront of AI marketing technology with ample opportunities for personal and professional growth.
• Unique opportunity to join on the ground floor of a fast-moving startup building at the center of AI.
• Tackle challenging problems while disrupting the $300BN legacy martech industry.
• Join an experienced team where you will have immediate ownership and impact.
• Competitive salary and bonus appropriate for experience and company stage.
• Significant equity package appropriate for company stage.
• Full medical, dental and vision benefits.
• PTO and remote work flexibility.
