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.

• 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.

• 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.
