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 Senior AI 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
- 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
- 8+ years of software engineering experience, with strong foundations in distributed systems, SaaS architectures, and modern stacks (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.

What We Do
Leading a successful professional service firm is an art. Running a profitable firm is a business. We understand this because our founder ran an IT Consulting firm for over 15 years. He grappled with the same challenges that professional service firm owners face today.
How do I know what my employees are working on? How can I connect time and expenses to clients or projects for billing? What resources do I have available? How can I see relevant reports on the firm’s performance? The list goes on.
The problems our founder faced drove the development of an AI-powered professional services automation platform specific to the needs of operational and financial leaders in professional services firms. We know that time tracking is more than timesheets. Time is information. We connect time with every part of your firm’s workflow so that all of the data you’ve collected with BigTime is the basis for metrics-driven reporting that informs your decisions. We live by our founder’s purpose - to help professional service firms combine the art of leadership with the business of being profitable.
