Celtic Engineering Solutions

What Celtic Engineering Solutions does

Celtic Engineering Solutions LLC is a privately-held engineering consulting firm headquartered in Murray, Utah, that specializes in rescuing stalled engineering projects. The firm is led by Sean O'Leary, PE, a licensed Professional Engineer, and operates as a cross-disciplinary practice spanning electrical engineering, embedded systems, firmware, mechanical design, and prototype-to-production transitions. Its target customer is the engineering team — typically at a small-to-mid-sized product company or hardware startup — that has hit a technical dead end, lost a key engineer, or accumulated undocumented design decisions it can no longer move forward on. Documented past engagements span at least seven verticals including consumer electronics (Lingua Bear), medical/healthcare (an iontophoresis device), industrial/agriculture (a robotic laser weed killer), consumer/RF (a mobile dog fence), roadside safety (a hazard beacon), museums (Kool Koor), and broader technology/hardware work (Veristride).

The firm's service architecture is built around a low-friction entry point: a 3-Checkpoint Assessment that progresses from PRD to SOW to quote, intended to reduce the procurement friction typical of consulting engagements for time-pressed engineering leaders. Beyond the assessment, Celtic delivers hands-on engineering execution to take projects from incomplete design through to manufacturable prototype and production-ready documentation. Distribution is supported by a content footprint of 133 field notes and an 18-project case-study portfolio, complemented by free engineering calculators deployed as lead magnets and a presence on YouTube, LinkedIn, and a blog/field-notes property.

The business model is professional services: quote-based, project-by-project engagements with no publicly disclosed pricing, rate card, or minimum engagement size. Multi-year contracts are described as possible but appear uncommon in the documented project set. There is no evidence of external funding, acquisitions, partnerships, or institutional investors; the firm operates as a principal-led practice with content marketing as its primary demand-generation channel.

Core offering

Celtic Engineering Solutions is a PE-led engineering consulting firm that helps companies define, troubleshoot, and stabilize stalled electrical, embedded, firmware, mechanical, and prototype-to-production projects. Engagements are anchored by a 3-Checkpoint Assessment (PRD/SOW/Quote) and span Firmware Rescue, PCB and System Troubleshooting, Prototype-to-Production Support, Mechanical Failure Analysis, Lead Engineer Gap Support, and Technical Consulting. Free browser-based engineering calculators and a Field Notes content library are used as client-project tools and lead generation assets.

Product overview

Celtic Engineering Solutions is an engineering consulting firm led by Sean O'Leary, PE, offering a portfolio of technical consulting services rather than a unified software product. The core offering consists of hardware engineering consulting (PCB debugging, firmware rescue, embedded systems, prototype-to-production support, and mechanical failure analysis) delivered through a structured engagement process anchored by the 3-Checkpoint Assessment (PRD/SOW/Quote). The company also provides free online engineering tools including Ohm's Law Calculator, Voltage Divider Calculator, LED Resistor Calculator, Pull-Up/Pull-Down Calculator, Relay Coil Calculator, and Solstice Pin Mapper. Additional resources include a Field Notes blog library and Resource Vault with templates and worksheets. The services target companies with stalled or at-risk engineering projects seeking definition, troubleshooting, or rescue support.
