Top Engineering Jobs

Build and operate scalable frontend applications, backend services, APIs, integrations, and customer-facing product features. Own projects from technical design through rollout, monitoring, and maintenance; improve system reliability, performance, and observability; collaborate cross-functionally; contribute to architecture decisions; mentor engineers; and use AI-assisted development tools to improve engineering productivity and quality.

Lead a hands-on engineering team developing Next.js. Write and review production code, own major technical initiatives, make architectural decisions, debug performance and reliability issues, coach engineers, improve execution, collaborate across Product, Design, Infrastructure, and Developer Experience, support open-source contributors, and participate in recruiting. The role focuses primarily on technical leadership and engineering execution while providing focused people leadership.

Build quality into product development across multiple teams through exploratory, risk-based, and automated testing. Develop and maintain web, API, and integration test coverage using Playwright and TypeScript; investigate application, pipeline, and system failures; improve testability, reliability, and developer feedback loops; identify systemic quality issues; and help teams make informed release and risk decisions.

Design and implement high-performance datapath features for load balancing, firewall rules, and Layer 7 protocols. Build scalable networking and security systems using C or C++, data structures, algorithms, and Unix/Linux optimization. Own architectural projects from conception through large-scale deployment while applying advanced knowledge of DNS, HTTP, TCP/IP, and SSL/TLS. Use AI tools to improve engineering workflows and problem-solving.

Designs, builds, tests, models, and analyzes optical, optoelectronic, and photonic experiments for quantum communications systems. Responsibilities include working with free-space and fiber optics, semiconductor device fabrication, data collection and analysis, process improvement, and troubleshooting complex systems with mechanical and electrical engineering teams.

Design and deliver developer tooling, frameworks, reusable templates, AI-assisted development infrastructure, authentication and identity platforms, and cloud-native services. Build and operate Java and AWS systems using Spring Boot and Kubernetes, establish engineering standards and guardrails, improve reliability and performance, and lead complex technical projects. Partner across teams to drive adoption, alignment, and measurable engineering productivity outcomes.

Develop and maintain Dynamics 365 Business Central AL extensions, integrations, environments, reports, and applications across two manufacturing companies. Lead an MRP integration, entity separation, Snowflake data warehouse pipelines, Power BI content, and a customer pricing portal. Provide ERP troubleshooting and occasional Level 1 support while collaborating with finance, operations, sales, and shop-floor teams.

Design, develop, test, and maintain cloud-based commercial tax software using full-stack technologies. Responsibilities include building features, resolving technical issues, conducting code reviews, collaborating with cross-functional teams, deploying containerized applications to Azure, documenting solutions, estimating development work, and mentoring junior engineers. The role also involves evaluating new technologies and ensuring software meets performance, security, scalability, and quality standards.

Develop and support mainframe-based financial reporting systems involving premiums, claims, and reserve calculations. Translate actuarial business needs into software changes, collaborate with technical and business experts, guide less experienced engineers, conduct code and design reviews, and improve engineering standards and core systems. The role requires strong mathematical reasoning, problem-solving, communication, prioritization, and knowledge of mainframe technologies, change management, SQL, software architecture, and design patterns.

Manufacturing Process Engineering Co-Op supporting production-floor operations, process optimization, loss and downtime analysis, waste reduction, equipment performance, root-cause investigations, Kaizen events, and continuous improvement. The role collaborates with engineering, production, maintenance, and quality teams while updating process maps, standard operating procedures, training materials, and work instructions. The co-op is fully onsite in Naperville, Illinois, with part-time academic-year and full-time summer schedules.
