As a Senior Software Engineer, Fullstack supporting Broad Arrow Group, you will own fullstack development across the systems that power Broad Arrow Auctions, from the public auction experience to the internal tools used on the auction floor. You'll work across a platform that spans Azure and AWS, including Microsoft Dynamics 365 and the Billboard software that displays lots and bids during live sales. Using modern technologies such as NextJS, TypeScript, React, and Node.js, you'll deliver fast, accessible, and reliable user experiences that hold up when the auction is live. You will contribute to architectural decisions that cross system boundaries, establish and maintain robust automated tests, support systems in production, and continuously raise the bar for patterns, practices, and overall quality across the Broad Arrow platform.
What you’ll do
Develop maintainable, scalable, secure, and resilient applications by:

• Crafting solutions through a deep understanding of business objectives, architectural intent, system interactions, and operational requirements, often working in ambiguous problem spaces and within the most complex parts of the system.

• Writing clean, human-readable code. Track and consistently apply the comments received on your code to future work.

• Contributing to architectural design with an emphasis on complexity, performance, maintainability, and security.

• Designing, implementing, and maintaining comprehensive automated unit, integration, and end-to-end tests. Possessing a strong understanding of when and how to apply each test type, including test data management, environment-appropriate execution strategies, and ensuring tests remain reliable and valuable over time.

Own and support features, modules, and products by:

• Being able to thoroughly explain and demonstrate how your product fits into the larger Broad Arrow Group and Hagerty ecosystem and how other services depend on it.

• Thoroughly understanding upcoming epics and features of your product, helping product managers craft good feature definitions, and being able to explain them to less experienced engineers.

• Helping to define key metrics that signal the health and performance of the product, monitoring them, and providing explanation for changes over time.

• Owning and updating the Billboard software used during live auctions, ensuring it is stable, accurate, and ready ahead of every sale.

• Actively practice troubleshooting and participate in the on-call support rotation for the team's production services, including support during live auction events.

Deepen technical expertise as an engineer by:

• Evaluating, adopting, and when necessary, designing client and server-side libraries, frameworks, and shared abstractions, establishing clear guidance on when they should be used, when they should not, and the tradeoffs involved.

• Defining and refining frontend and service integration patterns, including API contracts, data-fetching strategies, caching, and error handling that balance user experience, performance, operability, and long-term maintainability.

• Building and maintaining working expertise in the Azure portions of the Broad Arrow architecture, including accessing, deploying, and troubleshooting Azure artifacts and resources, while working alongside Hagerty's AWS environment.

• Understanding and integrating with Microsoft Dynamics 365 in Azure, keeping auction, consignment, and customer data flowing reliably between systems.

• Maintaining deep expertise in the client-side ecosystem, including browsers, rendering and hydration models, accessibility standards, performance diagnostics, and modern build/deploy workflows, to deliver resilient user experiences.

• Staying current with evolving frontend and platform technologies, thoughtfully incorporating improvements that raise user experience, system reliability, and/or developer productivity without chasing novelty.

Contribute to and engage in a collaborative environment by:

• Being an active participant in all team activities: team ceremonies, banter, troubleshooting, design discussion, work breakdowns, etc.

• Observing team practices and behaviors, working with your manager on ways to improve them, and explaining and modeling them.

• Helping less experienced engineers effectively explore topics that are unfamiliar to them and participate in deliberate practice with them in those areas.

• Helping teammates understand what it means to be good stewards of the products on which you are working.
