Original job description

Principal Systems Engineer Fabri is seeking a Principal Systems Engineer to architect, design, and deliver the in-house equipment and infrastructure that defines our manufacturing processes. This is a foundational role: you will work directly with the executive team to shape Fabri’s technical roadmap, report to the CEO, and own mechanical systems that span every step of our process. Your work will directly determine Fabri’s scalability, cost and throughput curves, automation strategy, and the architecture of future facilities. You will make and execute on critical build vs. buy decisions, develop first-of-their-kind equipment on aggressive timelines, and create hardware that radically expands what our process engineering teams can do. This role is expected to grow into technical leadership and the buildout of Fabri’s in-house equipment and mechanical engineering organization. We are looking for someone who thrives in high-ownership startup environments, is comfortable with ambiguity, and can move seamlessly between first-principles analysis, detailed machine design, and hands-on execution on the shop floor. You will “build the machines that build the machines” for some of the US’ most critical industries. 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 on the Billerica/Burlington border. 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. 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. The Role As Principal Systems Engineer, you will own the design, development, and deployment of Fabri’s core manufacturing equipment. You will operate bidirectionally with process engineering: translating process requirements into hardware, and using mechanical system constraints and opportunities to drive new process capabilities.

Reporting directly to the CEO, you will:

Define and communicate Fabri’s equipment and mechanical systems roadmap
Architect systems end-to-end, from concept through commissioning and production
Ensure that equipment choices scale economically in throughput, yield, automation, and facility footprint
Act as a systems engineer across tightly coupled mechanical, thermal, fluid, controls, materials, and process domains
Design, build, assemble, and troubleshoot critical hardware on tight timelines

This is not a role focused on incremental optimization. You will be expected to question every requirement, clearly define the underlying problem, explore the full solution space using first-principles physics, and deliver practical solutions fast.

Responsibilities

Lead the architecture and design of custom, first-of-kind manufacturing equipment across all process steps
Make and execute build vs. buy decisions based on physics, economics, scalability, and long-term roadmap impact
Work closely with process engineers to translate process needs into mechanical systems and use mechanical design to unlock new process regimes
Apply a systems-engineering mindset to track linked requirements, interfaces, and downstream consequences of design decisions
Drive rapid iteration: prototype, test, fail, learn, and deploy on short timelines
Define equipment architectures that support automation, reliability, maintainability, and future facility scale-out
Communicate complex, multidisciplinary technical decisions clearly to engineers and executive leadership
Help establish best practices for in-house equipment development, CAD practices, documentation, and commissioning
Over time, help recruit, mentor, and lead a growing mechanical engineering and equipment team

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.

Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a closely related field
Strong CAD, GD&T and DFM skills
5+ Years of designing and building complex equipment or vehicle systems
Deep first-principles understanding across multiple physics domains, including:
Thermodynamics, heat transfer, and fluid mechanics
Mechanics, dynamics, and machine design
Control systems and basic programming
Materials science (metals, polymers, ceramics), fracture mechanics, surface engineering, and wetting
Strong physics intuition and the habit of questioning assumptions and requirements
Systems-level thinking with the ability to reason across tightly coupled disciplines
Excel working in fast-moving startup environments with high ownership and ambiguity
Strong written and verbal communication skills
Have direct experience leading structured stage-gated Systems Engineering Technical Review (SETR) or similar processes on accelerated timelines in startup environments.

Fabri does not 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. Preferred Skills

Experience designing systems that have to operate at ultra high temperatures, high pressures, high vacuum levels, and/or handle corrosive, molten, or cryogenic fluids
Background in manufacturing equipment, or alternatively aerospace systems such as propulsion, turbomachinery, vacuum systems, or flight structures
Experience scaling hardware systems for throughput, reliability, and cost
Demonstrated ability to move from concept to working hardware quickly
Experience using meshing and simulation tools to validate equipment designs

What We Offer

A central role in reshoring and reindustrializing critical U.S. manufacturing capability
High ownership in solving some of the hardest problems in advanced manufacturing and industrial automation of the US’ most critical supply chains
Direct influence on Fabri’s long-term economics, scalability, and facility architecture
Close collaboration with leadership and cross-functional engineering teams
Competitive salary, meaningful equity, and significant growth potential
