We reverse engineer obsolete electronics, undocumented interfaces, proprietary communications, and abandoned software so valuable equipment can be repaired, integrated, or kept in service. We work with equipment owners, manufacturers, and service teams. Founder-led, New York.
Selected areas of prior work. Client names are confidential.
When a repair stops because the board is undocumented, the controller is obsolete, or the interface is proprietary, we recover how it works and identify a practical path forward.
We determine whether failed hardware can be repaired, reproduced, or functionally replaced without replacing the valuable system around it.
We connect older equipment to current controls, software, sensors, and networks without pretending the original system was designed for them.
The highest-value problems repeat. We turn one recurring obsolete controller or interface into a validated repair, replacement, or integration path your team can use across customers.
You keep the customer, field relationship, and regulated work. We take the cases that have crossed from normal service into deeper electronics and software engineering.
Start with the actual problem. Send the make and model, clear photos, failure symptoms, available documentation, what has already been tried, and whether this is one unit or a recurring installed-base issue. We will tell you quickly if there is a credible path.
Most work begins with a paid feasibility sprint. The deliverable may be a diagnosis, recovered protocol, repair procedure, replacement design, bridge, driver, or prototype. We test the result with you, document it, and scope repeat deployment only after the first unit works.
HIJ4CK is a founder-led engineering firm in New York City. We work where maintenance becomes engineering: obsolete electronics, missing documentation, proprietary communications, abandoned software, and difficult integrations. Our background spans hardware reverse engineering, cybersecurity, embedded systems, AI, robotics, aerospace, and scientific computing. The engineer who scopes the work does the work.
An otherwise valuable machine is down because a board is unavailable. The OEM no longer supports the system. A proprietary interface blocks a retrofit. Your service team keeps seeing the same unsupported component across customer sites. Send the make and model, photos, failure symptoms, what you have tried, and the approximate quantity. We will reply with a first technical read and an honest no if it is not a fit. No forms, no sales call.
