The success of your technology relies on the integrity of its build. Whether it's a new build or a retrofit, we handle everything from intricate cable routing to massive, fully configured automation systems without missing a beat.
Turnkey power distribution systems that keep mission-critical facilities online. Engineered, built, and tested under one roof.
Sophisticated control systems for heat rejection engineered for facilities where cooling failure isn't an option.
Prefabricated, UL-listed power cables custom-built to your exact data center and facility specs.
Precision-routed wire harnesses and power whips, tested for flawless signal and power delivery.
Turnkey electromechanical integration that synchronizes hardware, software, and controls into one tested, deployment-ready system.
ITAR-compliant solutions engineered for the unforgiving demands of defense and space.
One team. One roof. One timeline. Our in-house engineering, design, and manufacturing teams work as a single turnkey operation — turning custom projects on in days instead of weeks. A full custom shop, in-house and at your service.
Custom-engineered from the ground up for your specs, your footprint, and your process. Our design engineers work alongside you from concept through release to optimize for lead time, performance, and cost so every system is purpose-built for the job it has to do.
We engineer builds that are faster to produce, easier to scale, and cleaner to assemble without compromising quality or performance. DFM reviews happen early, so manufacturability is designed in from the start rather than engineered around later.
Assembly-aware design that cuts build time, reduces error rates, and eliminates integration surprises on the floor. Every assembly is engineered to come together predictably so production stays on schedule and the system you get matches the system you spec'd.
On-site startup, validation, and system handoff quickly get your equipment live. Our expert technicians and engineers in power, control, and mechanical systems ensure commissioning is a smooth launch, not a bottleneck.
Comprehensive environmental stress screening (ESS), functional testing, and performance validation on every assembly before it ships. We find the failures in our facility so you don't find them in yours.
Rapid prototyping to pressure-test your design before you commit to production. Whether it's a first-article build, a proof-of-concept, or a short-run pilot, we turn prototypes in days so design decisions happen with real data, not assumptions.
Early-stage engineering reviews that validate concepts, stress-test assumptions, and de-risk your timeline before capital is committed. We help you answer the hardest questions early: cost, schedule, manufacturability, compliance, so the project you launch is the project you can actually deliver.
Engineered to the standards your industry demands. UL, IPC-A-610, IPC/WHMA-A-620, ISO 9001:2015, ITAR, IATF 16949, and WHMA, with the documentation, traceability, and process controls to prove it on every build.
Compromise isn't in our vocabulary. Capacity isn't either. The capacity you need now with the scale to match whatever comes next.
Our people take pride in helping clients bring their most ambitious plans to life. Infinite Capacity is FSE’s proprietary approach to scaling engineering, program management, and skilled labor through proven process and training which means we have the bandwidth to take on your program, no matter the size.
We operate from a state-of-the-art 85,000 square foot facility along the I-95 corridor between Baltimore and Washington D.C., giving us the physical scale and geographic reach to accelerate your deployments. And we run every program through APQP, Advanced Product Quality Planning, to launch on time, on budget, and with zero defects.
FSE is excited to announce its move to a new, 85,000 square foot, state-of-the-art facility in Elkridge, Maryland. This facility shows FSE's commitment to the county and to the future growth of the company.


We are looking for relentless problem-solvers to help engineer and assemble the hardware that powers the modern world. High stakes. Real impact.
