Manufacturing Software Engineer

Location: Boston MetroWest (relocation assistance) In-Office: 5 days a week Salary Range: $140K - 180K/year (depending on experience) + equity Benefits: Medical, Dental, Vision, 401K, unlimited PTO Fabri is seeking a highly skilled Manufacturing Software Engineer . In this role, you will build and own the software systems that automate manufacturing preparation, orchestrate factory operations, and turn process data into actionable intelligence. The Company We are an early-stage investment casting startup building a fully integrated digital foundry. Our mission is to deliver precision metal castings with unparalleled speed and cost-effectiveness. By leveraging our exclusive high-throughput additive manufacturing process and AI-driven design software, we can deliver castings in days, saving our customers critical time and money. We are well-capitalized and backed by top-tier investors and major customers, with significant funding raised in the past year. We've shipped our first customer parts and have generated significant commercial excitement in both the aerospace and industrial sectors. Fabri is located in Boston Metrowest. During this startup phase and for the foreseeable future, all employees will be on-site and closely involved with building and operating the end-to-end process. The Role As a Software Engineer focused on Manufacturing Intelligence, you will build the foundational systems that connect Fabri's 3D printing and casting processes, robotics, data infrastructure, and automation workflows. Reporting to the CTO, you will own the development of automated manufacturing pipelines that take parts from intake through printing, casting, post-processing, and inspection. You will sit at the interface between software, hardware, and operations, deciding what to automate, what to instrument, and how data and intelligence flow back into production decisions. This role emphasizes systems thinking, software ownership, and closing the loop between manufacturing execution and software intelligence. Responsibilities Design and extend automated workflow pipelines that prepare parts for manufacturing, including build preparation, scheduling, and execution across Fabri's custom 3D printing and casting processes. Build backend systems that orchestrate manufacturing workflows and dependencies across printing, casting, robotics, and post-processing. Integrate Fabri's internal systems with third-party manufacturing and operator tools (e.g., Tulip) to enable execution, monitoring, and operator feedback. Develop software to coordinate robotic workflows on the factory floor, including interaction between machines, robots, and post-processing steps. Design and implement data collection systems for structured and unstructured manufacturing data, including machine logs, sensors, scans, and operator inputs. Design and maintain databases and storage systems (e.g., Postgres, TimescaleDB) for time-series, geometric, and operational data. Build analytics and monitoring tools to identify trends, anomalies, and root causes in manufacturing and process data. Develop and deploy rule-based or machine learning models for defect detection, castability assessment, and process monitoring. Close the loop by integrating model outputs back into automated workflows, scheduling decisions, and operator tools. Support cloud infrastructure and compute (AWS or similar) to scale data processing, workflow execution, and model deployment. Qualifications Even if you don't meet every qualification, we encourage you to apply for this role. We value curiosity, problem-solving skills, and strong fundamentals. A minimum of 3 years of professional software engineering experience. Strong backend or systems engineering experience (C++17 or later and Python). Experience building data pipelines, backend services, or infrastructure in ambiguous, early-stage environments. Familiarity with AWS infrastructure and batch compute workflows. Comfort working closely with manufacturing and operations teams. Strong communication skills and ability to work collaboratively across multidisciplinary teams, in a fast-paced, innovative environment. Bachelor's degree in Computer Science, Engineering, or a related technical field. Preferred Skills Prior startup experience or ownership of end-to-end systems. Knowledge of database design (e.g., Postgres) and data visualization techniques (e.g., Grafana). Experience with manufacturing execution systems, industrial software, or IoT data collection. Applied machine learning experience, especially with temporal or spatial data. You have experience working at the interface between software, hardware, and operations, deciding what to automate, what to instrument, and how data and intelligence flow back into production decisions. Front-end experience for building internal tools and dashboards. Fabri is not able to provide visa sponsorship for this position. To comply with ITAR regulations, candidates for this role must be US nationals (i.e., US citizens or lawful permanent residents) to be considered. What We Offer Opportunity to work at the cutting edge of digital manufacturing and AI-driven design. Broad technical scope and autonomy. Collaborative and innovative work environment with real technical authority. Competitive salary, meaningful equity, and strong growth opportunities. Fabri is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees. We foster an environment where safety and commitment to quality are central in everything we do.
