ADP is hiring a Lead Application Developer!

**Please note this is a hands-on, individual contributor role and will NOT involve managing people*\

• 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 within a scrum team to bring the designs and ideas to life for new or improved web applications. This work will support a mix of internal and external clients. You will work with clients, product managers, architects, software engineers, and more to plan, design, develop, test, and implement impactful solutions that support close to a million small businesses.

You will start your day on a scrum call to prioritize and track work. Within the team you work on, you will choose user stories to work within a sprint cycle. You will spend most of your day developing and testing your code. Every 2 weeks, you will be involved in the release activities.

To thrive in this development career, you’ll need to be an expert in C# and .net framework and have a firm grasp of UI technologies like Node and React. You’ll also need to be an expert in SQL Server data access and Stored Procedures. Although experience with the full stack is advantageous for this role we are looking for someone with a flair for back-end tech. Like our best developers, you are an enthusiastic creator eager to learn and take on stretch assignments. You strive to learn new technologies and find ways to incorporate what you learn into building your products.

As a Senior Lead Developer, you will work closely with your team to lead and guide projects to success. You’ll have a hands-on role designing, developing, debugging, and deploying software solutions where you can leverage your expertise with code complexities. You’ll also serve as a mentor to the junior developers.

Pace should not scare you. We still find time for a healthy dose of fun.

WHAT YOU’LL DO:
Here’s what you can expect on a typical day:

● Agile. You’ll start each day with a scrum, working in a team to understand responsibilities, identify issues, and communicate coding priorities while choosing user stories to complete. You will also participate in other agile ceremonies, including scheduled sprint demos, where you will present your work to hundreds of colleagues and stakeholders.

● Build teams that thrive. As an experienced leader, you want everyone to shine. You’ll start each day by checking in with your engineering team to identify priorities and challenges. You’ll find a way to make the team’s day go smoother. You are constantly looking for ways to share your knowledge, motivate others and keep everyone engaged and productive.

• Build Products. You will use your technical expertise to review your team’s work and help your people excel in an Agile environment. You’re proactive and hands-on. When you see a potential issue, you never leave things hanging and unfinished. When you and your team deliver a finished product, it’s as polished as you could make it.

• Variety of work. There is no typical day. You could be checking in with a team in India one minute, meeting with leadership to review initiatives for the coming quarter later and tomorrow handling a few ad hoc requests from your peers in other departments.

• Influence and inspire confidence. You are comfortable presenting to senior leaders, product owners, and peers with a compelling voice that you demonstrate through executive presence, leading change, and creating clear executive-level communications on milestone achievements.

• Experience. You have extensive 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.

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 find 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.

Ready to architect platforms that operate at serious scale?

Software Architect - NestJS, NodeJS, Vue - .NET backgrounds welcome

• Hybrid working in Hampshire
• Up to 110,000 + benefits

We’re partnering with a fast-scaling UK SaaS company building high-performance, data-driven platforms used by commercial teams to better understand and engage their customers.

They’re now looking for a Software Architect to shape the next generation of their customer-facing systems; designing scalable, cloud-first solutions capable of handling high data throughput and large data sets.

The Environment

The platform has evolved from a Microsoft / C# / .NET foundation into a modern stack including:

• NestJS, NodeJS, Vue
• Redis, SQL Server & Snowflake
• AWS (cloud-first architecture)

Strong .NET Architects who’ve worked in modern cloud and micro-services environments, or who can operate confidently across Node/TypeScript ecosystems, are absolutely encouraged to apply.

What matters most is architectural depth, SaaS scalability experience, and strong engineering principles.

The Role

This is ideal for someone who has progressed from hands-on engineering into architecture and still understands what great code and great systems look like.

You’ll:

• Design large-scale, high-performance SaaS architectures
• Lead microservices and event-driven design initiatives
• Champion DevOps-aligned architecture patterns
• Work across distributed/offshore teams
• Operate comfortably at both strategic and deep technical levels
• Influence AI architecture and modern data practices

What We’re Looking For

• 3-5+ years in a Software Architect role
• Strong engineering background (C#/.NET or modern JS/TS stacks)
• Experience within mature B2B SaaS environments
• Deep knowledge of cloud architecture (ideally AWS)
• Experience with microservices, event-driven systems
• Strong understanding of OLAP, OLTP, ETL & data warehousing
• DevOps-first mindset
• Excellent stakeholder engagement skills

Interested?

If you’re an Architect who wants real influence in a scaling SaaS environment - without being boxed into one technology - this is a strong opportunity.

Are motivated to modernise and improve platforms

Communicate clearly and confidently

Want long-term impact rather than short-term project work

If you are a .NET Developer who can balance maintaining a live production system with helping move it toward modern architecture, we would love to hear from you.
