Senior Software Developer

WHAT YOU'LL BE DOINGThe Senior Software Developer plays a key role in designing and delivering enterprise software solutions that connect systems, improve business processes, and support operations across Jensen Infrastructure.

Reporting to the Software Development Manager, you'll work closely with Business Analysts, business stakeholders, and fellow developers to solve complex business challenges through thoughtful application design, API integrations, automation, and modern development practices. You'll also bring senior-level technical judgment to the team, helping guide solutions and supporting the growth of other developers.

A highlight of your day-to-day will include:

Designing and implementing APIs and system integrations that connect enterprise applications and move data reliably between systems.

Designing and developing web applications, including PHP-based solutions, that support employees and business operations.

Using AI-assisted coding tools to accelerate development while applying the experience and technical judgment needed to review, validate, and improve generated code.

Partnering with Business Analysts and business stakeholders to translate operational needs into practical, scalable software solutions.

Providing senior-level technical guidance through solution design, code reviews, development standards, troubleshooting, and continuous improvement.

Supporting and mentoring other developers while contributing to a collaborative team environment focused on delivering high-quality solutions.

WHO WE ARE LOOKING FORYou're an experienced software developer who enjoys solving complex problems, building useful applications, and collaborating with others to deliver technology that makes work easier. You bring strong technical judgment, communicate well with both technical and non-technical partners, and are comfortable giving and receiving direct feedback while keeping the team's goals in focus.

We're looking for someone who wants more than their next coding assignment. This is an opportunity to take on challenging development work, help shape solutions, mentor others, and contribute to the technology supporting a growing organization. You'll have the autonomy to own your work, the opportunity to influence how solutions are built, and a team that values candid communication, accountability, and continuous learning.

In our culture — everyone matters.

Demonstrated professional software development experience independent of AI-assisted coding tools.

Experience working collaboratively within a software development team.

Preferred qualifications include:

Bachelor's degree in Computer Science, Software Engineering, Information Systems, or a related field, or an equivalent combination of education and experience.

Experience with Symfony or another modern PHP development framework.

Salesforce development experience, including Apex, is a plus.

ALL ABOUT JENSEN INFRASTRUCTURE Much like you, our founder, Don Jensen was looking for a way to support his family, so he started his Company in 1968. Since founded, we've been supporting communities across Arizona, California, Hawaii, Missouri, Nevada, and Washington.
