Contract Data Streaming Jobs in Illinois (NOW HIRING)

We are seeking a Senior Software Engineer in e‑Commerce Fulfillment to build our next‑generation, global event‑driven orchestration layer. This Macro‑focused software role is responsible for developing the high‑throughput fabric that coordinates distributed business logic across our entire supply chain e‑Commerce ecosystem. Instead of managing brittle, point‑to‑point batch integrations, you will build and own the central event mesh, distributed state machines, and global data contracts that ensure reliable, real‑time order routing, inventory visibility, and fulfillment state orchestration.

• This position is fully remote
• This role is an Individual Contributor

• Execute the systematic modernization of legacy transactional backend data flows into scalable microservices, ensuring high availability and seamless data consistency during the transition.
• Embed advanced distributed tracing, structured logging, and real‑time telemetry metrics into our orchestration pipelines to guarantee absolute visibility into complex end‑to‑end data flows.
• Work closely with product managers and team members to own the design, scalability, and delivery of high‑volume data streams utilizing modern message brokers (e.g., Kafka, RabbitMQ) to ensure loose coupling and reliable event delivery across the enterprise.
• Design and implement highly resilient distributed coordination patterns (Event‑Driven Architectures) to manage complex, multi‑system fulfillment lifecycles.
• Adhere to and promote engineering guardrails and best practices, focusing heavily on implementing services to continuously validate, observe, and publish system data, completely mitigating system drift and ghost‑state errors.
• Perform thorough code reviews, ensuring high standards of code quality, structural maintainability, and microservice performance.
• Identify and resolve complex technical issues and bugs within asynchronous communication paths, distributed transactions, and data caching layers.
• Contribute to architectural discussions and decisions by ensuring architectural decoupling of all routing rules and environment parameters into runtime configurations and feature flags to eliminate deployment bottlenecks.
• Drive the creation and maintenance of high‑quality documentation by adhering to robust release engineering and automated deployment gating protocols before any code activates.

• Strong expertise in software design and architectural patterns.
• Deep understanding of agile software development methodologies and the full software development lifecycle.
• Excellent problem‑solving, analytical, and critical‑thinking skills.
• Strong communication, collaboration, and leadership skills, with the ability to effectively interact with cross‑functional team members.
• Proven ability to mentor and guide other engineers in technical skills.
• Proficiency in multiple programming languages and technologies relevant to our stack.
• Experience with designing and developing scalable, high‑performance, and reliable software solutions in an iterative way.
• In‑depth knowledge of software testing strategies and automation.
• Familiarity with cloud platforms (e.g., AWS, Azure, GCP) and microservices architecture.
• Understanding of database design, performance tuning, and security best practices.

• Bachelor’s degree in Computer Science, Software Engineering, or a related field (or equivalent practical experience).
• 5+ years of experience building high‑scale, fault‑tolerant backend applications and microservices using strongly‑typed ecosystem (Java/JVM, .NET/C#, or equivalent enterprise backend languages).
• Hands‑on mastery of asynchronous event patterns, message queue architectures, stream processing, and solving for data‑at‑rest vs. data‑in‑transit challenges (e.g., Kafka, RabbitMQ, or cloud‑native event buses) managing high‑volume data centralization.
• Deep understanding of distributed transactions, idempotency, eventual consistency, and how to handle distributed state‑machine failures gracefully.
• Experience with technical aspects of complex backend projects from initial system design through production deployment and automated scale testing.
