Job summary

Celestica is seeking a Hardware DFT & Testability Engineer (PCBA) to ensure testability and maximum coverage are embedded into PCB hardware designs early in the design cycle. This upstream pre-layout gatekeeper role focuses on ICT access, boundary scan chains, and MTRS-driven coverage models.

The successful candidate will audit schematics, drive testability decisions, and collaborate with hardware, PCB layout, and software teams to deliver high-yield, debug-ready releases.

Qualifications

• 4+ years of experience in PCBA DFT, ICT, or manufacturing test engineering.
• Bachelor's degree in Electrical or Electronic Engineering.
• Strong knowledge of boundary scan (IEEE 1149.1) and testability reviews.

Responsibilities

• Perform pre-freeze audits of schematics vs DFT rules and test point access.
• Model MTRS coverage and identify gaps before manufacturing.
• Dispositon findings with design teams to add test points and boundary scan.
• Verify coverage on the first ICT/flying-probe fixture and document gaps.
• Assist with functional test definitions and early build debug on the manufacturing floor.

Job description

Job Title: Senior Lead, Hardware DFT & Testability Engineer (PCBA)

Country: USA

State/Province: Texas

Role Focus: Board-Level Schematic & Layout Gatekeeping | Structural ICT Probe Access | IEEE 1149.1 Boundary Scan | MTRS Coverage (Note: This is strictly a PCBA hardware role, NOT an ASIC/Silicon, RTL, or Software QA role).

Summary

At Celestica, we don't just manufacture high-complexity technology, we design, engineer, and optimize the hardware powering the future. As a global leader in design, engineering, and manufacturing services, our teams partner with world-changing brands across cloud infrastructure, aerospace, defense, healthtech, and advanced electronics. Located in Richardson, TX, our site offers a collaborative, fast-paced environment where your technical voice directly impacts the physical products shaping tomorrow's technology landscape.

Celestica is seeking a Hardware DFT & Testability Engineer (PCBA) to ensure testability and maximum test coverage are embedded into printed circuit board (PCB) hardware designs long before layout freeze. In this role within our DFx Center of Excellence, you will serve as an upstream design gatekeeper. You will perform in-design testability reviews, audit physical test point access for In-Circuit Testing (ICT), configure board-level boundary scan chains, and model structural and functional test coverage against key manufacturing targets to drive high-yield, debug-ready releases.

(Note: Candidates with strong hands-on backgrounds in structural In-Circuit Testing (ICT) fixture development—such as Teradyne, Keysight 3070, or flying probes—who wish to transition into upstream pre-layout design gatekeeping are highly encouraged to apply.)

Detailed Description

• Pre-Freeze Audits: Review electrical schematics and high-density PCB CAD layouts against the core DFT rule set prior to layout freeze. Enforce physical requirements such as test pad pitch, pogo-pin/probe-to-component clearances, and keep-out zones.
• Coverage Modeling: Model structural and functional coverage against the Manufacturing Test Requirements Specification (MTRS) and quantify coverage gaps before manufacturing begins.
• Finding Disposition: Partner directly with hardware design, PCB layout, and software teams to resolve testability issues through test point additions, boundary scan chain corrections, or agreed-upon design alternatives.
• Validation & Verification: Verify actual achieved coverage on the first physical test fixture (e.g., ICT, flying probe) and document discrepancies against pre-layout claims.
• Site Support: Assist with functional test definition and early build debug in collaboration with Technical Region Leads (TRLs) and local test SMEs on the manufacturing floor.
• Rule Evolution: Propose targeted DFT rule set updates derived from test escapes, physical fixture strain, and post-build rework.
• Formal testability reviews and fully dispositioned DFT findings prior to CAD freeze.
• Structural and functional coverage models mapped against the MTRS.
• Empirical evidence packages for achieved coverage on first fixtures.

Key Success Metrics

• Total designed-in coverage achieved on the first physical fixture.
• Complete resolution and closure of DFT findings prior to layout freeze.
• Minimization of test escapes and repeat testability issues across product lines.
• Must-Have: Strong background in board-level Design for Testability (DFT), electronic schematics, and high-density PCB layout checks.
• Highly Valued: Hands-on experience with In-Circuit Testing (ICT) platforms (e.g., Keysight 3070, Teradyne TestStation, Takaya flying probe), including an understanding of bed-of-nails fixture constraints.
• Core Technical Skills: Experience evaluating multi-device IEEE 1149.1 Boundary Scan / JTAG chains, debug/provisioning access, and test point physical accessibility.
• Coverage Expertise: Practical knowledge of MTRS coverage modeling, functional test strategy, and hardware bring-up.
• Out of Scope: Experience restricted solely to silicon-level ASIC DFT (RTL, ATPG, MBIST, scan insertion inside the die) or pure software validation does not align with the physical board-level requirements of this role.

Typical Experience

• 4+ years of experience in PCBA Design for Testability (DFT), In-Circuit Test (ICT) Engineering, or Manufacturing Test Engineering in a complex electronics or EMS environment.

Typical Education

• Bachelor's degree in Electrical Engineering, Electronic Engineering, or a related technical discipline.

Physical Demands

• Duties of this position are performed in a normal office environment.
• Duties may require extended periods of sitting and sustained visual concentration on a computer monitor or on numbers and other detailed data.
• Repetitive manual movements (e.g., data entry, using a computer mouse, using a calculator, etc.) are frequently required.
• Occasional travel may be required.
