Onsite Full Time General
About the Role
We are hiring multiple Senior Software Engineers (Full Stack) to join a high-impact product engineering team building modern, scalable software used at meaningful scale.
While this is a true full-stack role , we are open to engineers who naturally lean Front-End (React/web-first) or Back-End (Ruby/Elixir preferred) — as long as they are comfortable contributing across the stack.
This is not a siloed environment. Engineers are expected to think holistically about architecture, performance, scalability, and user experience.
We are specifically seeking candidates located in Arizona who are open to regular in-person collaboration.
What You'll Do
* Design, build, and maintain scalable full-stack applications.
* Develop modern web applications using React (web-first) .
* Build and maintain backend services using Ruby or Elixir (strong preference) ; Java experience is acceptable.
* Design and consume RESTful APIs.
* Refactor legacy systems for scalability, performance, and maintainability.
* Contribute to shared UI components and design systems.
* Collaborate closely with product managers, designers, and QA.
* Participate in architectural discussions and technical roadmap planning.
* Improve CI/CD pipelines and development workflows.
* Conduct code reviews and mentor junior engineers.
* Proactively identify opportunities to modernize systems and improve engineering standards.
* Evaluate and leverage AI tooling to improve development efficiency and product capabilities.
Required Qualifications
* Bachelor's degree in Computer Science, Software Engineering, or related field (or equivalent experience).
* 4-6+ years of professional software engineering experience.
* Experience working across both front-end and back-end systems.
* Strong experience with:
* React (required for front-end contributions)
* RESTful APIs
* Backend experience in one or more of:
* Ruby (preferred)
* Elixir (preferred)
* Java
* Experience with relational databases (MySQL or similar).
* Familiarity with Git and CI/CD pipelines.
* Strong understanding of modern software architecture principles.
* Excellent communication and collaboration skills.
Nice to Have
* React Native experience (plus, not required).
* Experience with event-driven systems.
* Experience optimizing performance at scale.
* Familiarity with Azure DevOps or similar cloud tooling.
* Agile experience (Jira, Confluence).
* Experience modernizing legacy systems.
What We're Looking For
* Engineers who think beyond tickets and care about architecture.
* Ability to contribute across the stack even if you have a strength area.
* Strong ownership mindset.
* Comfort working in a collaborative, high-growth environment.
* Interest in building scalable systems that evolve over time.
