Software Engineer, Infrastructure (C++) - Build the Backbone of a Software-Driven FactoryBillerica, MA | On-site
Opportunity SummaryA well-funded manufacturing startup is building a software-driven foundry that delivers precision metal castings to aerospace, defense, and industrial customers far faster than traditional suppliers. Every machine, operator, and production job depends on the software platform that ties the factory together.
You will own that platform. This role builds the backend services, databases, and tooling that connect machines and workflows, and owns the build systems, CI/CD, and cloud infrastructure that keep both the software team and the factory running. You will report to the CTO and work on-site alongside the people who rely on your systems.
Job Duties- Build backend services, databases, and internal tools that support day-to-day factory operations
- Develop software for workflow automation, job setup, scheduling, and production execution
- Integrate internal systems with machines, operator tools, and external platforms
- Design reliable data capture for process data, machine logs, inspection results, and operator input
- Own build systems, CI/CD pipelines, deployment, AWS resources, and developer tooling
- Write C++ for backend systems, automation, data processing, and manufacturing orchestration
- Work with manufacturing, process engineering, and operations to turn production pain points into software
Qualifications- 3+ years of professional software engineering experience
- Strong programming skills in modern C++ (C++17), which will be your primary language
- Hands-on infrastructure experience with build systems such as CMake, CI/CD pipelines, containers, and running services in production
- Experience building backend systems, automation tools, or technical internal tools
- Strong debugging and systems-level thinking
- Comfortable working where requirements are loosely defined
- Interest in manufacturing, hardware, or physical processes, and willingness to work on-site
- U.S. person status (U.S. citizen or lawful permanent resident) required under ITAR
Preferred Experience- Cloud deployment on AWS, containerization, or batch compute
- Time-series databases, Postgres, data modeling, or analytics pipelines
- Exposure to MES platforms, factory automation, or sensor, machine log, and IoT data
- Internal platforms or workflow automation systems
- Python experience
- Early-stage startup experience
Why Join Us- Build core software for a brand-new manufacturing process from the ground up
- Own the platform that the entire factory runs on
- Work directly with machines, operators, and real production data
- Own broad, high-impact systems at an early stage
- Early-employee equity with real upside as the company expands from one foundry to many
- Fast career growth: early hires are expected to step into technical leadership as the team scales
- Small, hands-on team with no bureaucracy, where decisions happen in days rather than quarters
- A mission that matters: rebuilding domestic production of castings used in aircraft engines, defense systems, and energy infrastructure
- Competitive base salary
- Medical, dental, and vision coverage
- 401(k) plan
- Unlimited PTO
Compensation Details$150,000 - $190,000 + equity
ITAR RequirementThis position requires access to technical data controlled under the International Traffic in Arms Regulations (ITAR). Applicants must be U.S. persons (U.S. citizens or lawful permanent residents). Visa sponsorship is not available.
