Job description

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.

Requirements
  • 5+ years of professional software engineering experience, with meaningful full-stack scope.
  • Solid experience with Ruby on Rails, including ActiveRecord, background job processing, API design, and service-oriented patterns.
  • Strong Javascript proficiency, including SPA architecture, component design, state management, and front-end performance.
  • Track record of owning and delivering complex features or projects end-to-end.
  • Strong RESTful API design experience, including versioning, authentication, and third-party integrations.
  • Solid database fundamentals, particularly MySQL or similar relational databases, including schema design and query optimization.
  • Ability to participate in technical discussions and contribute to architectural decisions.
  • Experience mentoring junior or mid-level engineers and contributing to a culture of technical excellence.
  • Familiarity with marketing or customer engagement platforms - campaign management, personalization engines, A/B testing, or equivalent - is a plus.
  • Good communication skills: able to explain technical concepts clearly to both technical and non-technical audiences.
  • Experience with agile development methodologies and working within cross-functional product teams.
  • Familiarity with AI-assisted development tools (e.g., GitHub Copilot, Cursor, Claude Code) and interest in evaluating where AI/ML capabilities can be integrated into product features.

Bonus Points For
  • Experience with Go (Golang), Vue.js, and/or Node.js.
  • Experience integrating LLM APIs (e.g., Anthropic, OpenAI) or building AI-powered product features.
  • Familiarity with AI/ML concepts such as embeddings, vector search, retrieval-augmented generation (RAG), or fine-tuning.
  • AWS experience, including deploying and scaling cloud-based applications.
  • Hands-on experience with OpenSearch for search or analytics.
  • Use of Redis for caching, session management, or background jobs.
  • Exposure to Kafka or similar messaging systems in high-throughput environments.
  • Familiarity with Docker for local development or production deployment.
  • Experience with CI/CD pipelines and deployment workflows.
  • Exposure to GDPR, CCPA, or similar data privacy regulations.
  • Background in B2B SaaS products or high-volume transaction systems.
