Senior Full Stack Web Application Engineer ES6 & PHP

Brimar Industries in Garfield, NJ 187 mi javascript php ecmascript-6 sass oop

About The Position

We’re looking for an experienced full-stack developer with a proven track record of planning, developing, and deploying complex web applications. The successful candidate will work with other front-end developers, back-end developers, UX/UI designers, and other departments to gather requirements for assigned projects. You will have full responsibility for translating these requirements into technical plans. You will also be responsible for executing those plans using ES6, PHP, Sass, Handlebars, and MySQL. You will report to the department’s project manager for code reviews and progress reports.

We’re a small team, but we think you’ll be surprised to see the types of projects we complete in-house rather than using “off the shelf” software. Request an interview and ask to see the responsive, multi-site framework we’ve custom-developed for ourselves. Now is the perfect time to join the team and help shape this awesome application.

About You

  • You have 5+ years of experience building large applications while adhering to requirements and meeting deadlines.

  • You’re a team player who is able to adapt to convention, but also comfortable proposing and overseeing the adoption of better ways to do things.

  • You recognize the importance of an organized workflow.

  • You’re a strong object-oriented programmer, able to find the patterns and abstractions within complex requirements.

  • You’re comfortable managing web servers and understand why uptime is so important.

  • You’re a long-term thinker who recognizes that shortcuts are often not in the best interest of the company.

  • You’re a strong communicator who enjoys defending your solutions to a team that is passionate about clean, well-structured, object-oriented code.

  • You take ownership of the projects assigned to you.

  • You like to make things that you can be proud of.

  • Most importantly, you program not just because it pays the bills, but because you find it fun.

What You’ll Do

  • Develop new user-facing features.

  • Translate requirements into fully formed plans.

  • Communicate ideas and discuss your plans at sprint planning meetings to ensure the team understands your objectives and to inform your approach to the final form of the application and its code.

  • Review the plans and code produced by other talented engineers. Offer guidance to improve our results.

  • Engineer object-oriented MVC-style components.

  • Utilize JavaScript (ES6), PHP 7, HTML (Handlebars), and CSS (Sass/SCSS) to translate mockups and documentation into fully functional features.

  • Write solid, standards-compliant code while recognizing performance, scalability, and security.

  • Study the business and its products so you can be confident that your work will serve us well.

What You Need to Know

  • ES6: Expert-level understanding of modern, class-based JavaScript. Experience with React or Angular is not applicable to this project.

  • PHP: Expert-level understanding of object-oriented PHP in a custom-developed MVC framework.

  • Sass, Less, or CSS: Expert-level understanding of responsive, cross-browser styling for an application where visual fidelity is critical. Experience with Bootstrap is not applicable to this project.

  • Exceptional planning, organization, and documentation skills.

  • Excellent communication skills with a willingness to ask questions and work with the team — we love helping each other achieve the team’s goals.

  • Personal project management experience with a proven track record of completing projects on time and to scope.

  • Familiarity with build tools, such as Gulp.js.


Senior Web Developer

Apply your .NET skills as a lead developer within a multi-disciplinary A-team of experts. Day to day, you'll be collaboratively solving problems, architecting solutions, and expanding your mastery of CMS web development. If you are a tenacious problem-solver who thrives when digging deep into code and complex data sets, you will fit right in.

We specialize in the design and development of enterprise .NET websites, so experience working with a.NET content management system (Ektron, Episerver, Umbraco, Sitecore, etc.) is required.


When you become a Senior .NET developer at Diagram, you'll get assigned to an account team with a strategist at the helm. Each team is responsible for working with a small group of clients, understanding their business goals, and building out a strategic roadmap to help push them forward. In your role, you can expect a healthy mix of writing code, gathering requirements, participating in design critiques, architecting solutions,and coordinating with your team and clients. Each account team operates autonomously, meaning that the strategies your team propose will drive the work you do—what you can accomplish is limited only by your collective ideas and abilities.

  • Integrating third-party solutions through Web Services or other messaging frameworks

  • Basic knowledge of IIS and setting up local sites

  • Using Git and version control

  • Familiarity with HTML, CSS, JavaScript, jQuery, and other JavaScript frameworks


Our organizational model involves building out small collaborative teams that kick ass. If you work best when you're handed a blueprint and left alone to build in solitude for weeks on end, you might not be a good fit. Diagram developers prefer to be in the mix of things and would rather contribute to solving real problems with code than to just take orders. You are naturally curious, eager to learn, and play nice with others. As a developer at Diagram, you are treated as a professional, working with other professionals for common goals.Day to day, some of your responsibilities will include:

  • Work with modern hosting technologies: Azure DevOps, CI/CD, AWS, Episerver DXC, Umbraco Cloud

  • Analyze, troubleshoot, and resolve issues on enterprise client websites

  • Adapt to and learn new and emerging .NET/CMS technologies

  • Communicate and convey technical concepts to clients, team members, and project managers

  • Contribute to functional requirements and technical documentation

  • Work both independently as well as collaboratively within a team

  • Propose and architect technical solutions that help drive our clients forward

  • Estimate effort for development tasks
