Job description

Who we are 💙

Here at Waitwhile we're on a mission to eliminate the 1 trillion hours people spend waiting in lines every year. Our platform combines virtual waitlists, scheduling, real‑time updates, messaging, and analytics to make access to places, services, and events seamless, online or in person. Trusted by 10,000+ companies, Waitwhile has already helped over 150 million people enjoy a radically better waiting experience. Our clients include IKEA, Louis Vuitton, Costco, Delta Airlines and thousands more. We’re just getting started, and we need your help.

The role

As a member of our Service Intelligence team, you’ll focus on the backend systems, infrastructure, and data foundations that power Waitwhile at enterprise scale and enable our clients to access valuable insights on their daily operations. You’ll work closely with our VP of Engineering and our cross‑functional engineering teams, contributing to scalable, high‑impact features that improve both our platform and user experience.

This is also where we’re building the foundation for our AI initiatives, working with rich operational data to unlock smarter insights around things like wait times, staffing and service performance.

Our tech stack includes TypeScript and JavaScript, NodeJS, Firebase, Firestore, BigQuery, Angular and React, running on Linux in Google Cloud Platform.

While engineers may specialize deeply, Waitwhile increasingly values end‑to‑end product ownership and cross‑stack collaboration as the organization scales. We’re open to different backgrounds; what matters most is your drive, problem‑solving acumen, and ambition to level up your skills while building something that truly makes a difference.

This position is based in Stockholm at our offices on Kungsgatan 32. We’re a hybrid company and prefer that you work from the office at least 2 days per week, as we believe the best product gets built together, live.

What you’ll own

• Full engineering lifecycle including technical design, implementation, automated testing, deployment and production monitoring.
• Drive improvements to engineering best practices, tooling and code quality.
• Scalability, reliability, observability and compliance across services and internal platforms.
• Design, implement and evolve APIs, workflows and backend services that support core product functionality.
• Improve monitoring, logging, deployment systems and operational tooling to support long‑term platform health.

What skills you need

• 6+ years of experience building web applications.
• Strong experience with Node.js and designing scalable backend architectures.
• Cloud hosting and operations.
• Experience selecting and operating the right data storage solutions to ensure application responsiveness and scalability.
• Comfort in collaborating across the stack to support complete product experiences.
• Great communication skills, comfortable explaining complex concepts to cross‑functional teams.
• A bachelor's degree in Computer Science, Engineering or a related field.

Bonus Skills & Attributes

• Previously worked at a startup or on a SaaS product.
• Experience with infrastructure as code.
• Direct experience with Firebase, Firestore and/or BigQuery.
• Experience with monitoring, reliability engineering and operational best practices.
• Security‑minded approach to platform development.

A great place to work ❤️

We want Waitwhile to be an incredible place to work. We offer great benefits and perks, flexible working hours and lots of interesting challenges. We believe in making work fun and rewarding, care about your development and are committed to your success. Join Waitwhile at this exciting stage and help shape both our future and your own.

Waitwhile has a positive, diverse and supportive culture—we look for people who are curious, inventive, and work to be a little better every single day. We aim to be smart, humble, hardworking and, above all, collaborative.
