Senior Software Engineer, Full-Stack

We're looking for a Senior Full-Stack Engineer to help build our marketing and customer engagement platform. In this role, you'll design and develop data-driven, customer-facing features and backend services that power real-time personalization, campaign delivery, and transaction support. Our stack is Ruby on Rails on the backend and Vue.js on the frontend - and we value engineers who lead with strong product instincts, deep technical judgment, and a pragmatic mindset.

This is a great opportunity for an experienced engineer who enjoys owning features end-to-end, collaborating closely with cross-functional partners, and mentoring less-experienced teammates, with room to grow into broader technical leadership. We believe the best engineers today are fluent in AI - comfortable using AI-assisted development tools and thoughtful about how AI capabilities can be woven into product features and platform experiences.

This is a hybrid role based out of our Broomfield, Colorado office.

Responsibilities

• Full-Stack Development: Design and build robust, secure, and scalable systems across our Ruby on Rails and Vue.js stack, with ownership from API design and data modeling through to rich front-end experiences.
• Technical Contribution: Contribute to architecture and design discussions for key platform initiatives, and help establish and follow sound engineering patterns.
• Mentorship: Support the growth of junior and mid-level engineers through code reviews, design feedback, and pairing.
• Performance & Quality: Identify and drive improvements to backend and frontend performance, and help raise the bar for code quality, testing, security, and observability.
• Cross-Functional Collaboration: Partner with Product, Design, and Customer Success to translate business problems into sound technical solutions that deliver measurable outcomes.
• AI-Augmented Development: Leverage AI-assisted tooling to accelerate delivery, and contribute ideas on where AI capabilities can add genuine value to the product.
• Agile Delivery: Work effectively in an iterative, fast-paced environment - shipping frequently and adapting quickly.
• Incident Response: Participate in resolving production incidents and contribute to post-incident reviews that prevent recurrence.
