The Opportunity

Broker Tech builds products for the Convoy Platform at DAT, enabling brokers to match and execute shipments while they work seamlessly within their Transportation Management Systems (TMS). We partner with brokers to transform how they work, grow, and succeed by:

• Empowering Matching: Building smarter tools and visibility that boost broker match rates and strengthen carrier connections.
• Fueling Growth: Enabling brokers to expand through better pricing, new freight categories, and integrations.
• Ensuring Payments: Strengthening and automating broker payment processes to reduce risk and ensure reliability.
• Enabling Ideal Experiences: Delivering seamless workflows via APIs and webhooks between the Convoy Platform and TMSs, with self-service configuration and onboarding tools.

What You'll Do

Hands-on Development

• Write, test, and deploy production-quality code with guidance from senior engineers.
• Build and maintain backend services in Node.js/TypeScript and contribute to React frontends as needed.
• Implement and support message-driven workflows (Kafka/RabbitMQ) using existing patterns and reusable components.
• Improve code quality and maintainability as you deliver features (tests, refactors, documentation).

Collaboration & Growth

• Partner with product and business stakeholders to clarify requirements in a complex domain.
• Participate in code reviews (both receiving and giving) and incorporate feedback quickly.
• Learn the team's operational practices: monitoring, alerts, on-call support, and incident follow-ups.
• Grow ownership over time: take on increasingly complex tickets, then small projects.

What Excites Us About This Role

• As the Convoy platform expands into a critical marketplace for brokers, this team shapes outcomes that matter for broker workflows and reliability.
• High ownership with support: you'll ship meaningful work while learning from senior engineers in a complex, real-world domain.
• Lots of surface area: integrations, workflows, payments, messaging, and partner-facing APIs.

The Skills and Experience You'll Bring

• 2-5+ years of professional software engineering experience (or equivalent).
• Experience building production services in TypeScript/Node.js (or strong Java/C#/Go experience with willingness to ramp).
• Familiarity with React and modern frontend development fundamentals.
• Comfort working with APIs (REST preferred; GraphQL a plus) and collaborating on contracts.
• Familiarity with SQL databases (schema basics, writing queries, migrations with guidance).
• Exposure to async systems (queues/events) such as Kafka/RabbitMQ/SQS is a plus, or willingness to learn.
• Solid engineering fundamentals: debugging, testing, code quality, and clear written communication.

Bonus Skills 

• Experience with microservices in production.
• Hands-on exposure to Kafka/RabbitMQ patterns (retries, DLQs, idempotency).
• Docker/Kubernetes familiarity.
• CI/CD experience (tests in pipeline, safe deploy patterns, feature flags).
• Background in transportation/logistics or complex B2B integrations.
