BigTime is looking for an experienced Software Engineer to join our AI team! This is a fantastic opportunity to join a high-growth SaaS company! As a Software Engineer, you will be working across the entire application stack. You collaborate extensively to design, build, and test functionality in our award-winning, cloud based system. This is an exciting opportunity to work side-by-side with a team of talented individuals. Our goal is to be the leading AI-powered platform guiding Professional Services organizations to excel in delivery, resource, and financial management and grow profitably. The right candidate will be passionate about development and able to solve difficult technical problems in a fast-paced, agile environment.

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.

Now, we’re expanding our AI team to shape the future of agentic systems—and we’re looking for pioneers to help us lead.

The Opportunity

As a Software Engineer, you’ll architect and build agentic workflows that redefine how professional services firms operate. Using cutting-edge protocols like the Model Context Protocol (MCP) and Agent-to-Agent (A2A) collaboration, you’ll design AI systems that don’t just assist—they act, orchestrating workflows across tools, data, and teams.

You’ll collaborate with a world-class engineering team to push beyond traditional SaaS, embedding autonomy, reasoning, and intelligence into the very fabric of BigTime’s platform.

What You’ll Do

Design, develop, and maintain scalable Python applications and services

Architect MCP-based frameworks that enable LLMs to connect seamlessly with BigTime and third-party ecosystems (Salesforce, QuickBooks, Jira, Hubspot, Intacct, and beyond).

Design and implement agentic control planes for governance, security, and auditability—ensuring safe, explainable autonomy.

Orchestrate multi-agent workflows using A2A patterns, allowing agents to plan, delegate, and adapt across dynamic environments.

Benchmark agent performance with emerging standards (e.g., LiveMCP-101) to validate orchestration and execution.

Enhance resilience and scalability by building fault-tolerant, observable, and distributed AI-driven services.

Collaborate cross-functionally with product, data science, and platform teams to transform how professional services operate.

Continuously explore bleeding-edge AI methods and bring fresh ideas into production.

Who You Are

1-3+ years of software engineering experience, with strong foundations in distributed systems, SaaS architectures, and modern stacks (Python, React, C# .NET, SQL Server, MongoDB, Redis, AWS/Azure).

Proven experience with LLM-based systems and agentic AI workflows; hands-on familiarity with MCP, A2A, or related protocols is a huge plus.

Comfortable moving between monolithic and distributed systems; experience migrating legacy platforms into microservices/service-based architectures.

Strong problem-solving and debugging skills in complex environments.

Passionate about building AI systems that are secure, auditable, and production-ready.

Excellent communicator and collaborator—able to align technical design with business impact.
