Senior Software Engineer

We are seeking an experienced Senior Software Engineer to join our Chicago team. In this role, you will work across the full application stack to design, develop, and test features in our cloud‑based platform. You will collaborate closely with cross‑functional partners to deliver high‑quality, scalable solutions. We’re looking for someone who thrives in a fast‑paced, agile environment and enjoys solving complex technical challenges. If you’re passionate about building innovative software and contributing to a collaborative engineering culture, we’d love to connect.

Who We Are

BigTime is the AI‑powered professional services platform enabling intelligent decisions and delivering profitable growth. We’ve proudly been featured on Inc.’s 500 Fastest Growing Companies in America four years in a row and named one of Crain’s Best Places to Work three years running.

Our flagship SaaS platform powers 2,700+ consulting firms worldwide, tracking over $4B in billable time each year. We’re on a mission to become the leading AI‑driven platform guiding professional services organizations to excel in delivery, resource, and financial management.

The Opportunity

As a Senior Developer, you’ll take ownership of designing and building systems that power real, high‑impact workflows for our customers. You’ll work on problems that go beyond basic CRUD — things like orchestrating complex data flows, integrating with external platforms, and creating automation that removes friction from everyday work. You’ll help shape the architecture of our platform, make decisions about how things scale and operate in production, and build software that’s reliable and easy to evolve. This role gives you room to dive deep : one day you might be sketching out a new service boundary or designing an API contract, and the next you’re rolling up your sleeves to debug a tricky edge case in the stack.

You won’t be doing this in a vacuum. You’ll work with a strong engineering team that values clear thinking, pragmatic technical choices, and building things the right way. Your contributions will directly influence the direction of the product and how thousands of users experience it.

This role is not eligible for relocation assistance or visa sponsorship. Candidates must be authorized to work in the U.S. without current or future sponsorship.

What You’ll Do

• Design, build, and evolve core application features using React and either C# / .NET, Python
• Own and improve critical system integrations (Salesforce, QuickBooks Online, Jira, Sage Intacct, HubSpot), focusing on reliability, observability, and long‑term maintainability.
• Lead code reviews, influence coding standards, and help raise the quality bar across services and shared components.
• Work closely with product, support, and engineering teams to break down complex problems and turn them into scalable, thoughtful solutions.
• Shape technical direction by evaluating new tools, patterns, and practices—and introducing them when they create real value for performance, productivity, or maintainability.
