About The Position

E-Space is seeking a Senior Design-for-Test (DFT) Engineer to join their SoC design team. This role is responsible for defining and implementing comprehensive DFT strategies across complex digital SoC designs for 5G, IoT, and LEO satellite communications applications. The engineer will ensure robust testability and quality of silicon from early design stages through manufacturing tests. The company is focused on bridging Earth and space to enable hyper-scaled deployments of Internet of Things (IoT) solutions and services by building a highly-advanced low Earth orbit (LEO) space system.

Minimum 8+ years of hands-on experience in Design-for-Test (DFT) for complex digital ASICs or SoCs
Hands-on experience with industry-standard DFT tools such as Synopsys DFT Compiler, Tessent, or equivalent
Strong expertise in scan insertion, ATPG pattern generation (stuck-at, transition, IDDQ), and fault simulation
Experience with compression architectures (EDT, DFTMAX) and advanced DFT techniques
Working knowledge of MBIST architectures and embedded memory test strategies
Familiarity with JTAG/IEEE 1149.1, IEEE 1500, and IEEE 1687 (iJTAG) standards
Proficiency in scripting (Tcl, Python, Perl) for DFT flow automation and analysis
Experience collaborating with physical design and STA teams for scan chain closure
Strong understanding of digital design fundamentals and RTL design practices
Passion for mentoring engineers and scaling technical excellence across a team

Nice To Haves

Experience with IEEE P1838 (3D-IC test standards) or die-to-die interface test
Exposure to at-speed test methodologies, on-chip clock control for at-speed test, and diagnosis flows for yield improvement
Experience with system-level test and in-system test (IST) approaches
Familiarity with ATE platforms (Advantest, Teradyne) and test program development
Expertise in using programming languages and AI tools for test flow automation
Background in satellite communication, 5G NR, or IoT SoC designs

Responsibilities

Define and implement end-to-end DFT architecture and strategy for complex SoC designs, including scan, MBIST, BIST, and JTAG/IEEE 1149.x
Insert and verify scan chains, compression logic, and test wrappers using industry-standard DFT tools
Own the full ATPG lifecycle: verification, coverage analysis, pattern generation, and ATE bring-up
Perform fault simulation and analyze test coverage metrics to meet manufacturing test requirements
Collaborate with physical design teams to optimize scan chain ordering, routing, and test timing
Define and implement memory BIST (MBIST) and logic BIST (LBIST) strategies for embedded memories
Work with ATE teams to develop test programs and validate tester compatibility
Develop DFT automation scripts and integrate DFT flows into the overall design implementation flow
Perform DFT sign-off verification and resolve DRC/functional issues related to DFT logic
Document DFT specifications, methodology guidelines, and test coverage reports
