Parallel Computing Jobs in Illinois (NOW HIRING)

Join the Options Clearing Corporation (OCC) as a Solution Architect to design and lead the next generation of OCC’s clearing system, driving digital transformation across capital markets.

• Design the applications’ architecture across distributed and enterprise technology platforms, leveraging event‑driven architecture, publish/subscribe messaging, and microservices.
• Define and enforce architectural standards, patterns, and best practices across engineering teams.
• Design streaming and batch‑based systems that support both real‑time and scheduled data flow.
• Shape and guide the architecture of message‑based systems using Kafka or similar platforms to enable reliable, decoupled, event‑driven communication.
• Develop and oversee data architecture and integration strategies spanning streaming, batch, and message‑based processing.
• Own end‑to‑end solution architecture from ideation through implementation, documenting decisions and system diagrams.
• Guide the development and deployment of distributed, cloud‑native services, ensuring resilience, scalability, and cost‑efficiency.
• Collaborate with DevOps, platform engineering, and security teams to ensure architectures are operable, resilient, and aligned with organizational standards.
• Review designs and code to ensure alignment with architectural standards, security requirements, and regulatory/compliance needs.
• Troubleshoot and resolve complex, cross‑system issues across application, infrastructure, messaging, and data layers.
• Partner with engineering, data, and business teams to translate business requirements into robust, scalable technical solutions.
• Translate complex architectural decisions and trade‑offs into clear, actionable insights for business stakeholders and non‑technical audiences.
• Evaluate emerging tools, frameworks, and technologies, and provide recommendations for adoption.
• Mentor engineering teams on architectural best practices, distributed systems, event‑driven and batch processing design.

• Demonstrated experience in event‑driven and message‑based systems, transaction processing systems, distributed and parallel computing.
• Solid experience designing application architectures across distributed and enterprise technology platforms, including microservices and streaming or batch‑based applications.
• Experience with projects involving complex integration of disparate technologies/platforms and data.
• Experience architecting large‑scale distributed systems.
• Architect Kubernetes‑based deployment topologies for stateless services and on‑demand jobs, including horizontal pod autoscaling, multi‑AZ resilience, and cross‑region/on‑prem failover and disaster recovery strategies.
• Fluent in object‑oriented design, industry best practices, software patterns, and architecture principles.
• Experience defining and documenting architecture strategies, designs, and requirements across all enterprise architecture domains.
• Experience defining non‑functional requirements (NFRs) including performance, scalability, availability, and security, and ensuring application architecture satisfies them.
• Highly motivated with a strong sense of ownership of work and projects.
• Excellent oral and written communication skills.

• Software development experience in Java, Python, or C#, including building high‑throughput, low‑latency services for data‑intensive or transaction‑oriented systems.
• Strong knowledge of Kafka or other messaging/streaming systems, including topic design, partitioning strategies, and producer/consumer patterns.
• Fluent in object‑oriented design principles, software design patterns, and modern architecture practices (microservices, event‑driven architecture, domain‑driven design).
• Knowledge of identity and access management using OAuth2/OIDC flows, JWT‑based token validation, and integration with identity providers (ForgeRock, SailPoint).
• Knowledge of schema management and data serialization formats, preferably Protocol Buffers (Protobuf), including schema evolution.
• Understanding of data lake‑house architecture and table formats such as Apache Iceberg.
• Familiarity with Infrastructure as Code principles and tooling, preferably Terraform.
• Working knowledge of DevOps tooling and practices such as Git, Jenkins, Docker, Artifactory, ArgoCD, and others.
• Experience working with Cloud ecosystems (AWS, PaaS, K8s).

• BS degree in Computer Science, a similar technical field, or equivalent practical experience.
• 10+ years of relevant work experience.

• 6+ years of work experience in the capital markets industry.

• Hybrid work environment, up to 2 days per week of remote work.
• Tuition reimbursement to support continued education.
• Student loan repayment assistance.
• Technology stipend for remote work.
• Generous PTO and parental leave.
• 401(k) with employer match.
• Competitive medical, dental, and vision coverage.
