Job Description

Jahnel Group’s mission is to provide the absolute best environment for software creators to pursue their passion by connecting them with great clients doing meaningful work.

We get to build some of the most complex and compelling applications for our clients located across the country. We’re a fast-growing INC 5000 recognized company, yet we still work as a very close-knit team (100+ employees). We’re growing like crazy, and if you’re looking for the next place to call home, hit us up for a beer or coffee. 

Who We’re Looking For

We’re looking for a Senior Software Engineer (PHP) to join our team. Our ideal teammate is a strong full-stack engineer who thrives in open-source environments, enjoys tackling technical debt head-on, and embraces an AI-forward development mindset. You’re someone who doesn’t just write code—you evaluate it, challenge it, and improve it, especially when leveraging AI-assisted workflows.

You’ll play a key role across multiple high-impact initiatives, including modernizing legacy systems, enhancing mobile-cloud integrations, and contributing to new AI-powered applications. If you’re comfortable moving between backend and frontend, enjoy solving complex system challenges, and take ownership of your work—this one’s for you.

Primary Responsibilities

  • Upgrade and modernize legacy systems, including Symfony and PHP versions, while addressing technical debt and deprecations.
  • Execute and maintain comprehensive regression testing to ensure system stability throughout upgrades.
  • Design, build, and maintain scalable backend systems using PHP, Symfony, and the LAMP stack (Linux, Apache, MySQL).
  • Develop and enhance frontend applications using Angular (AngularJS and modern Angular).
  • Build and maintain RESTful APIs to support system integrations and external services.
  • Contribute to mobile and cloud system integrations, enabling seamless communication between applications and backend services.
  • Support inventory and inspection workflows through system enhancements and integrations.
  • Collaborate on the development of AI-driven applications, including microservices that leverage machine learning models.
  • Review, validate, and refine AI-generated code to ensure quality, correctness, and performance.
  • Participate in architectural discussions, sprint planning, and daily standups as part of an embedded team.
  • Take ownership of features and systems, from design through deployment and iteration.
  • Advocate for clean code, maintainability, and modern development best practices.

Skills and Qualifications

  • 5+ years of professional software engineering experience.
  • Strong expertise in PHP and the Symfony framework.
  • Solid experience working within the LAMP stack (Linux, Apache, MySQL, PHP).
  • Proficiency in Angular (both AngularJS and modern Angular).
  • Experience designing and consuming RESTful APIs.
  • Strong understanding of MySQL and relational database design.
  • Proven experience managing technical debt, including framework upgrades and deprecation handling.
  • Experience with full-stack development across backend and frontend systems.
  • Familiarity with AI/ML concepts and tools, with an interest in integrating AI into development workflows.
  • Ability to review, validate, and improve AI-generated code.
  • Strong problem-solving skills and adaptability across different technologies.
  • Experience working with open-source technologies and environments.
  • Proficient with Git and collaborative development workflows.
  • Strong communication skills and ability to work within cross-functional teams.
  • Bachelor’s degree in Computer Science, Engineering, or related field (or equivalent experience).

Nice to Have

  • Experience with Python and Flask for backend services.
  • Exposure to AI/ML model development or integration.
  • Experience with mobile app integrations and backend support.
  • Familiarity with inventory, logistics, or ERP-related systems.

  • 100% Remote for the right candidate
