DFT Engineer
DFT Engineer (Senior / Staff)
At Niobium Microsystems, we develop high performance microelectronic products to enable the secure collection, processing, and distribution of critical data. We are a trusted partner for DoD and commercial customers whose solutions require lower power, higher efficiency, and proven security.
Founded as a 2021 spinout from a world-class security and computing systems R&D company, our team combines decades of experience in advanced semiconductor design with experience in advanced cryptography. Niobium is headquartered in Dayton, Ohio with additional locations in Portland, Oregon; and Columbus, Ohio. We will not be limited by geography for the right candidate.
POSITION DESCRIPTION /
Niobium Microsystems is seeking a Senior / Staff DFT Engineer with 8+ years of relevant industry experience. This role will serve as a technical lead responsible for defining and executing Design-for-Test (DFT) strategy across complex SoC designs.
As a DFT Engineer, you will own the full test insertion flow from early architecture through post-silicon validation. You will collaborate closely with RTL, physical design, and test engineering teams to ensure high fault coverage, manufacturability, and first-pass silicon success.
JOB RESPONSIBILITIES /
Primary Responsibilities:
Overview
Own and drive end-to-end DFT strategy for complex SoCs, from architecture through silicon bring-up
Serve as DFT lead for major subsystems or full-chip execution
DFT Architecture & Planning
Define and implement DFT architecture including scan, compression, and MBIS
Establish DFT insertion strategies at RTL and/or netlist stages
Implementation & Integration
Drive scan chain stitching, compression insertion, and clock/reset domain handling
Integrate DFT features across subsystems including SRAM, register files, and mixed-signal blocks
Collaborate with physical design to meet timing, routing, and signoff requirements
Verification & Coverage Closure
Execute ATPG and fault simulation to achieve high fault coverage targets
Develop and validate test patterns for scan, BIST, and low-power modes
Track and drive DFT sign off criteria including coverage, waivers, and escape analysis
ATE & Post-Silicon Bring-Up
Partner with test engineering to translate patterns to ATE platforms
Support silicon bring-up, debug failing patterns, and perform yield analysis
Conduct shmoo analysis and root-cause failures
Leadership & Methodology
Drive DFT methodology improvements, automation, and flow optimization
Develop scripts and infrastructure for scalable DFT flows
Represent DFT in cross-functional reviews and program milestones
DESIRED SKILLS & EXPERIENCE /
Required Experience
B.S. or M.S. in Electrical Engineering, Computer Engineering, or related field
8+ years of hands-on DFT experience in ASIC or SoC design
Strong expertise in scan architecture, ATPG, compression techniques, and MBIST
Experience driving DFT from RTL through GDSII, including physical design collaboration
Hands-on experience with ATE bring-up and post-silicon debug
Proficiency in scripting (Tcl, Python) for automation and flow development
Technical Experience
DFT tools such as Siemens Tessent, Synopsys TestMAX, or equivalent
Familiarity with RTL design and simulation tools (Verilog/SystemVerilog, VCS, Xcelium)
Experience with large-scale SoC integration and multi-clock/multi-power domains
Strong understanding of DFT timing, physical constraints, and signoff requirements
Experience working with ATE platforms such as Advantest or Teradyne is a plus
BENEFITS /
Competitive salaries
Employer paid health care
Employer contribution to health savings account
Flexible time off
Flexible work location with remote options
Location Preferences: Portland, OR;Columbus, OH; Dayton, OH; Fayetteville, AR; or San Francisco, CA
