The Opportunity

We are seeking a Senior Software Engineer to join a growing engineering team in Tempe, Arizona.

This is a hands‑on development position focused approximately 80% on back‑end engineering and 20% on front‑end development. The role will have significant ownership across API development, AWS serverless architecture, microservices, mobile and web applications, and integrations with internal and external platforms.

The engineering team is highly business-facing, so this is not purely a heads‑down development role. The successful candidate will work directly with business stakeholders, architects, and other engineers to understand requirements, recommend solutions, and deliver scalable applications.

Current and upcoming initiatives include:

• Building new applications and platforms from the ground up
• Developing APIs supporting mobile applications

• Integrating AI capabilities and new technology platforms
• Building APIs and integrations connecting internal systems and external vendors
• Supporting operational and enterprise applications
• Improving scalability, reliability, and automation across the technology environment

What You’ll Do

• Design, develop, test, and deploy scalable back‑end services and APIs
• Build serverless applications and microservices using AWS Lambda, DynamoDB, S3, and other AWS technologies
• Develop primarily with Python and Node.js
• Contribute to front‑end applications using React and React Native
• Design and consume APIs, including GraphQL‑based services
• Partner with architects and developers on technical designs and architecture decisions
• Work directly with business stakeholders to gather requirements and recommend technical solutions
• Translate technical concepts for non‑technical stakeholders
• Coordinate UAT and gather feedback from business users and pre‑release testers
• Participate in CI/CD, testing, deployment, and production support
• Lead technical workstreams and take ownership of projects from design through delivery
• Conduct code reviews and mentor junior engineers

What We’re Looking For

• Bachelor’s degree in Computer Science, Information Technology, Engineering, or a related technical field
• Ideally 6–8 years of software development experience; strong candidates with 4–5+ years may also be considered
• Strong experience with back‑end engineering, API development, and microservices
• Hands‑on experience with AWS serverless technologies
• Experience with AWS Lambda, DynamoDB, S3, or similar AWS services
• Strong development experience with Python and/or Node.js
• Experience working with both SQL and NoSQL databases
• Experience with modern CI/CD tools and development practices
• Experience owning or leading development projects
• Experience conducting code reviews and/or mentoring junior engineers
• Strong communication and stakeholder management skills
• Ability to gather business requirements and translate them into technical solutions
• Recent U.S.-based project experience strongly preferred

Nice to Have

• Jira
• Enterprise system integrations

The base salary range for this position is $125,000–$140,000, plus a 10% target annual bonus. First-year bonuses are prorated based on start date.

This position follows a hybrid schedule in Tempe, Arizona, with Monday through Thursday onsite and Friday available as a flexible remote day.
