The ARC Robotics Strategy & Virtual Systems team is a dynamic, fast-paced group responsible for designing and developing Digital Twin applications for manufacturing plants across the globe. As a Senior Software Engineer on the Digital Twin team, you will design, build, and scale core services, SDKs, and high-performance 3 D runtime components that power immersive digital twins across products, factories, and operations. This role is ideal for someone who enjoys owning features end-to-end — from schema and API design through front-end implementation and production deployment. What You’ll Do (Responsibilities)Design and implement software for robotic simulation environments and automation frameworks. Build and integrate 3 D modules (e.g., rendering, simulation, physics, spatial indexing) with platform services via well-designed APIs and data contracts. Work across the stack using modern front-end frameworks (e.g., React or similar), Type. Script/ JavaScript, and service-oriented backends (e.g., Node.js, Python, Java, or C#)Build and iterate on web-based playback and visualization tools that rely on Web. RTC, Web. Sockets, and streaming media pipelines to deliver simulation replays. Work with databases and storage systems to organize simulation outputs, logs, and artifacts for fast retrieval and inspection. Collaborate with robotics engineers, data scientists, and system architects to integrate software into autonomous platforms. Optimize code for efficiency, scalability, and reliability in real-time systems. Conduct testing, debugging, and validation of software components. Document software designs, processes, and best practices for maintainability and knowledge sharing. Serve as a Subject Matter Expert (SME) for at least one platform or application component. Your Skills & Abilities (Required Qualifications)Bachelor’s degree in Computer Science, Computer Engineering, or a related field 5 years of experience developing full-stack software applications in multiple programming languages such as Java, C#, C , Python, JavaScript/ Type. Script with modern frameworks (e.g., React, Angular)Experience with systems integration and/or interoperating with Digital Twin or IoT platforms. Understanding of code quality analysis results and remediation mechanisms. Strong oral and written communication skills, with the ability to work independently and collaboratively across teams. Experience designing or consuming APIs and platform components; familiarity with reusable SDKs/libraries and REST/g. RPC/ Web. Socket services. Solid version control and testing practices (e.g., Git, unit/integration testing, build automation, CI/ CD)What Can Give You a Competitive Edge (Preferred Qualifications)Master’s degree in Computer Science, Computer Engineering, or a related field. Experience with simulation, modeling, or real-time analytics; exposure to mentoring peers or coordinating small engineering efforts is a plus. Experience with time-series or metrics systems (e.g., Prometheus, Influx. DB, Open. Telemetry, Grafana)Experience with job orchestration/compute platforms (e.g., Kubernetes, job queues, batch processing)Experience with visualization libraries (e.g., D 3, Plotly, Chart.js) for graphs, timelines, and dashboards. Experience handling and visualizing large binary artifacts (logs, traces, 3 D/2 D simulation outputs, video)Experience in a cloud environment (AWS, Azure, GCP) and with infrastructure-as-code tools. Familiarity with manufacturing, automotive, or industrial domains. Understanding of cybersecurity best practices for connected systems This role is categorized as hybrid. This means the selected candidate is expected to report to a specific location at least 3 times a week {or other frequency dictated by their manager}. The selected candidate will be required to travel >25% for this role. This job may be eligible for relocation benefits.
