The Role

We’re hiring a Senior Full-Stack Developer (Backend-Focused) to help build and scale the next generation of Boostly’s platform — powering the future of restaurant marketing through world-class engineering.

You’ll be part of a small, fast-moving team tackling complex backend challenges — from designing scalable APIs and optimizing database performance to integrating AI and advanced messaging technologies. You’ll balance technical execution with mentorship and architectural influence, helping us transition from “make it work” to “make it great.”

Success in this role means delivering reliable, elegant systems that scale effortlessly as Boostly grows from hundreds to thousands of customers, all while keeping performance, quality, and user experience top of mind.

This is a full-time, in-person role based in our Lehi, Utah office.

What You’ll Do

Design, build, and scale robust backend systems using Node.js, Express, and PostgreSQL.

Architect and maintain high-performance APIs that power our core platform and integrations.

Collaborate with Product and Design teams to deliver seamless, full-stack features using React and modern front-end frameworks.

Set engineering best practices for code quality, testing, and deployment.

Mentor other developers and help shape our technical culture as we grow.

Identify and solve bottlenecks in performance, scalability, and reliability.

Contribute to the adoption of AI-assisted development tools that boost velocity and quality.

Continuously improve our DevOps pipelines and infrastructure in collaboration with the engineering team.

What We’re Looking For

Must-Haves :

5+ years of full-stack development experience , with a strong focus on backend systems.

Deep proficiency in Node.js, Express, and PostgreSQL .

Solid understanding of API design, database architecture, and system scalability.

Experience with React or other front-end frameworks.

Proven track record of shipping production-grade software that scales.

Pragmatic, product-oriented mindset — you prioritize solving customer problems over technical perfection.

Ability to work in-person and collaborate closely in a fast-paced, early-stage startup environment.

Nice-to-Haves :

Experience with TypeScript , AWS, or containerized environments (Docker, Kubernetes).

Familiarity with messaging, loyalty, or marketing technology systems.

Prior experience scaling systems from startup to growth stage.

Passion for leveraging AI as a force multiplier in development workflows.

Background mentoring engineers or leading small teams.

Why You’ll Love Working at Boostly

Impact & Growth :

Help scale a platform already driving millions in incremental revenue for restaurants.

Tackle complex engineering challenges with direct visibility to business impact.

Join a Series A rocket ship with clear product-market fit and strong investor backing.
