Sr. Electro-Mechanical Assembler

One Stop Systems Inc•Escondido, CA

9h•$31 - $33•Onsite

About The Position

One Stop Systems is seeking a highly skilled and experienced Senior Electro-Mechanical Assembler to assemble complex, high-value computing and electro-mechanical systems at its Escondido manufacturing facility. The role requires extensive hands-on experience with precision mechanical assembly, electrical wiring, electronic component integration, and complete system builds. The assembler must be technically proficient and self-sufficient, able to interpret engineering documentation, perform complex assembly operations independently, and resolve assembly-related challenges with minimal supervision. This role supports multiple product configurations in a high-mix, low-volume manufacturing environment, rather than focusing on repetitive production tasks. Following product-specific orientation, training, and qualification, the successful candidate is expected to become independently productive on assigned OSS products within approximately 2–4 weeks. The position reports to the Production Manager and involves assembling ruggedized computer systems, server chassis, electronic enclosures, and custom integrated equipment. Work includes mechanical assembly, electronic component and wiring integration, documentation interpretation, troubleshooting, quality checks, production execution, and collaboration with Engineering, Quality, and Production. The role also supports prototypes, new product introductions, established production programs, and continuous improvement. The position is full-time and on-site in Escondido. Compensation is hourly, with a range of $31–$33. The workweek is 40 hours, with irregular hours possible for emergency production needs or problems that arise.

Requirements

At least 5 years of directly relevant hands-on experience in complex electro-mechanical assembly, equipment integration, or comparable technical manufacturing.
Demonstrated experience independently assembling complex mechanical systems incorporating electrical and electronic components.
Strong mechanical aptitude and proficiency in precision assembly, hardware installation, alignment, fastening, and torque application.
Practical experience installing electronic assemblies, power supplies, wiring, cables, connectors, and other system components.
Ability to read and interpret mechanical drawings, BOMs, assembly instructions, and basic electrical wiring diagrams.
Proficiency using common mechanical assembly tools, calibrated torque tools, and measuring instruments.
Ability to independently plan and execute assembly activities using established work instructions and engineering documentation.
Demonstrated ability to identify and troubleshoot mechanical and electrical integration issues at the assembly level.
Experience with complex products requiring attention to detail, consistent workmanship, and careful component handling.
Ability to work effectively with limited supervision, exercise sound judgment, and communicate technical issues.
Strong commitment to safety, quality, productivity, and accountability.
Ability to work a regular 40-hour workweek and be prepared to work irregular hours for emergency production needs or problems that arise.
Ability to lift up to 75 pounds; frequently stand, sit, walk, handle objects, feel with hands, and reach with arms; occasionally climb, balance, stoop, kneel, crouch, or crawl.
Ability to operate around high-voltage components and moderate noise conditions.
Ability to wear protective clothing and glasses in some areas.
Vision abilities include close and distant vision, color perception, peripheral vision, depth perception, and the ability to focus; regular hearing and speaking communication is required.
Formal engineering education is not required; relevant hands-on experience, demonstrated technical competency, and the ability to independently build complex systems are the primary selection criteria.

Nice To Haves

Experience assembling ruggedized servers, industrial computers, electronic systems, aerospace or defense equipment, medical devices, or similarly complex electro-mechanical products.
Experience in high-mix, low-volume or custom manufacturing environments.
Experience with complete equipment builds rather than exclusively repetitive assembly-line operations.
Familiarity with AS9100D, ISO 9001, or other structured manufacturing quality systems.
Knowledge of IPC standards or other relevant electronics workmanship standards.
Experience supporting first-article builds, prototypes, new product introductions, or engineering changes.
Familiarity with ERP systems, electronic work instructions, and manufacturing documentation.
Additional experience in cable fabrication, crimping, soldering, electrical measurement, or basic functional testing.

Responsibilities

Independently assemble complex electro-mechanical systems, including ruggedized computer systems, server chassis, electronic enclosures, and custom integrated equipment.
Perform precision mechanical assembly of chassis, structural components, mounting hardware, brackets, electronic assemblies, and related components.
Install and integrate electronic components, power supplies, PCBAs, cooling systems, cables, connectors, and wiring.
Route cables, install connectors, manage wires, and complete electrical interconnections according to approved engineering documentation.
Execute complete system builds involving multiple mechanical, electrical, and electronic subassemblies.
Use hand tools, power tools, torque-controlled equipment, measuring instruments, and other manufacturing tools appropriately.
Read and interpret mechanical drawings, assembly drawings, BOMs, wiring diagrams, and manufacturing work instructions.
Organize and execute assembly operations using approved manufacturing documentation; identify and communicate discrepancies in drawings, BOMs, component fitment, and instructions.
Adapt to new product configurations and engineering revisions while following change-control procedures.
Identify and resolve routine mechanical assembly, fitment, installation, and wiring issues within established procedures.
Recognize incorrect components, missing hardware, misaligned parts, damaged connectors, and potential assembly defects; determine when Engineering or Quality support is needed.
Collaborate with Manufacturing Engineering, Design Engineering, Quality, and Production to address build challenges.
Identify opportunities to improve assembly methods, reduce rework, and increase production efficiency.
Assemble products to engineering specifications, manufacturing procedures, customer requirements, and applicable workmanship standards, including applicable AS9100D procedures.
Apply ESD protection, FOD prevention, component-handling, and material-traceability practices.
Perform in-process checks and verify assembly accuracy, completeness, and workmanship before transferring systems to subsequent operations.
Maintain accurate production records and document manufacturing activities, discrepancies, and inspection results as required.
Work independently with minimal supervision while meeting production schedules, safety requirements, and quality expectations.
Transition efficiently between product configurations and assembly requirements; support prototype builds, new product introductions, and established production programs.
Promptly communicate material shortages, documentation problems, assembly challenges, and production risks.
Maintain an organized, clean, and safe work area consistent with 5S principles.
Assist in mentoring less-experienced assemblers and sharing established best practices when needed.
Complete required OSS safety, quality, ESD, and product-specific training and become familiar with OSS manufacturing documentation and processes.
Meet workmanship and quality expectations, minimize defects and rework, and contribute to continuous improvement in assembly quality, manufacturing efficiency, and production performance.
Follow safety requirements, wear protective clothing and glasses in designated areas, and observe meal and rest-period guidelines.
