ADP is hiring a Principal Architect.

  • Are you empathetic to client needs and inspired by transformation and impacting the lives of millions of people every day?
  • Are you looking to join a dynamic, inclusive team environment with a culture of collaboration and belonging?

Well, this may be the role for you. Ready to design what's next? In this role, you will work alongside ADP product owners to understand their challenges in creating, upgrading, or augmenting our products. Then, you'll design technical solutions and guide a team of developers as they implement your design.

Every day, you will promote architectural initiatives that drive revenue and improve efficiency aligned with business strategy. Each day, you will start with a scrum and identify priorities within the current sprint or discuss a new project. Then you'll create designs to guide the developers while they code what you design. If something is particularly critical, you may have to roll up your sleeves and code. As the team lead, you'll communicate and collaborate with your team and cross-functionally, acting as the technical reference.

To thrive in this role, you have ten-plus years of experience in architecture, design, and building large-scale distributed services-oriented systems will be essential to your success. You'll need versatile knowledge of coding languages, including front-end, scripting, and back-ends like Java, Javascript, .React, JS frameworks, or others. Our best developers are creative problem solvers who love a challenge. If you get stuck, you find a workaround and keep going. You never give up. This role requires you to have clear, compelling, and influential communication skills to succeed. You will constantly mentor developers and collaborate with peer architects on other teams. You must be adept at teaching, leading, and influencing. As part of our team, you will influence product success and help shape our industry.

What'll You Do

Here's What You Can Expect On a Typical Day

  • Blueprints and Strategy. You will influence and govern current and future architectural blueprints and promote architectural initiatives that generate revenue, improve efficiency, and support our business strategy. You will ensure that what we do solves both enterprise and local needs.
  • You'll start every day with a scrum, working together to understand responsibilities, identify issues, and communicate design and coding priorities.
  • Your role is to design 50%, and code 50%. Once you create your design, you will guide developers to bring it to life using tools like Java, React, or others. You will review their code, refine it if necessary, and jump in and code critical areas yourself.
  • Inevitable challenges will arise, and we'll rely on you to look for a solution. You love a challenge and revel in the opportunity of finding one.
  • Learning and Teaching. You're the technical expert on the team, so when issues arise, you'll be the one developing a fix. When you present a design, you are open to feedback from your engineer team since you believe collaboration helps strengthen your ideas, especially if someone thought of something you hadn't considered. After all, we all have the same goal, develop the best solutions we can for our clients.
  • Variety of work. There is no typical day. Some days you will dedicate to design or mentoring team members, while others you will spend on projects for quality assurance, security, UX, or any number of other functions.
  • You have 12+ years of experience in relevant skills gained and developed in the same or similar role.
  • To Succeed In This Role

  • You'll have a Bachelor's degree OR equivalent.
  • Prior experience that would give you extra comfort in the role includes :
  • Proficiency in Java / JEE technologies, JSON, React, Kafka
  • Hands-on experience with Springboot and Spring integrations
  • RDBMS and NoSQL databases such as Mongo or DynamoDB
  • GIT, Jenkins, Ansible, Public Cloud (AWS or Azure)
  • Front-End Development

  • Strong proficiency with React and component-based UI development (custom widgets, reusable components).
  • Experience with modern Web 2.0 frameworks, including React, Redux, and jQuery.
  • Solid understanding of HTML5, CSS3, and CSS preprocessors (SASS / LESS).
  • Back-End Development

  • Strong understanding of Java and Spring Boot / Hibernate and experience building Java-based applications.
  • You'll Love Working Here Because You Can

  • Have courageous team collaboration. Courage comes from how associates are willing to have difficult conversations, speak up, be an owner, and challenge one another's ideas to net out the best solution.
  • Deliver at epic scale. We deliver real user outcomes using strong judgment and good instincts. We're obsessed with the art of achieving simplicity with a focus on client happiness and productivity.
  • Be surrounded by curious learners. We align ourselves with other smart people in an environment where we grow and elevate one another to the next level. We encourage our associates to listen, stay agile, and learn from mistakes.
  • Act like an owner & doer. Mission-driven and committed to leading change, you will be encouraged to take on any challenge and solve complex problems. No tasks are beneath or too great for us. We are hands-on and willing to master our craft.
  • Give back to others. Always do the right thing for our clients and our community and humbly give back to the community where we live and work. Support our associates in times of need through ADP's Philanthropic Foundation.
