"Semiconductor jobs" is not one job. It is dozens of careers across design offices, clean rooms, test floors and research labs. This guide maps the main roles, what each one does day to day, and what you need to get in.
The big picture: three worlds
Semiconductor careers fall into three broad worlds, matching the stages of how a chip is made:
- Design (front-end and back-end): turning an idea into a verified, manufacturable layout. Mostly office-based, and India's largest semiconductor employer today.
- Manufacturing (fab): running the processes that print chips onto silicon wafers. New in India with the Dholera fab and others coming up.
- Assembly, test and packaging (ATMP/OSAT): cutting, packaging and testing chips. India's first plants started production in 2026.
Chip-design roles
| Role | What you do | Core skills |
|---|---|---|
| RTL design engineer | Write the chip's logic in a hardware language and build blocks like processors, interfaces and accelerators. | Digital design, Verilog/SystemVerilog, computer architecture |
| Design verification (DV) engineer | Build test environments that try to break the design before it is manufactured. One of the most-hired roles. | SystemVerilog, UVM, assertions, coverage, scripting |
| Design for test (DFT) engineer | Add structures so every manufactured chip can be tested quickly for defects. | Scan, ATPG, BIST, JTAG |
| Physical design engineer | Turn the logic into a real layout: floorplan, placement, routing, timing closure and power. | Synthesis, place-and-route, static timing analysis, TCL |
| Analog / mixed-signal engineer | Design circuits that handle real-world signals: amplifiers, data converters, PLLs, power management. | Analog circuits, CMOS device physics, SPICE simulation |
| Layout engineer | Draw transistor-level layouts for analog and custom circuits that meet manufacturing rules. | Layout tools, DRC/LVS, matching techniques |
| FPGA / emulation engineer | Prototype chip designs on FPGAs so software can run before the chip exists. | FPGA flows, RTL, debugging, embedded C |
| Post-silicon validation engineer | Test the real chip in the lab once it comes back from the fab. | Lab equipment, Python, board bring-up |
Manufacturing, packaging and test roles
| Role | What you do | Typical background |
|---|---|---|
| Process engineer | Own a fab step such as lithography, etch or deposition and keep it stable and improving. | Electronics, chemical, materials, physics |
| Equipment engineer | Install, maintain and optimise multi-crore fab and packaging tools. | Mechanical, electrical, mechatronics |
| Yield / quality engineer | Use data to find why chips fail and raise the share of good chips per wafer. | Any engineering branch plus statistics and data skills |
| Packaging engineer | Design and qualify chip packages, including advanced multi-die packaging. | Mechanical, materials, electronics |
| Test engineer | Write test programs that check every chip on automated test equipment. | Electronics, programming |
| Technician | Operate and support clean-room and test-floor equipment. | Diploma / ITI with specialised training |
Beyond the core
- EDA / CAD engineers build and support the software tools designers use.
- Applications and field engineers help customers use chips in their products.
- Researchers in universities and labs work on new devices, materials and architectures, often via an M.Tech or PhD.
- Founders build fabless startups, supported by schemes such as DLI.
Which branch leads where?
- ECE / EEE: every design role, plus test and process.
- CSE / IT: verification, FPGA, EDA software, post-silicon automation and AI-hardware tools. Verification in particular welcomes strong programmers.
- Mechanical / Mechatronics: equipment, packaging, facilities.
- Chemical / Materials / Physics: process engineering, materials and research.
- Diploma / ITI: technician roles in fabs and OSATs, a fast-growing need.
How to get in
- Nail the fundamentalsDigital electronics, CMOS basics and, for design, computer architecture.
- Pick a track earlyFront-end, back-end, analog or manufacturing. Depth beats breadth.
- Build proofProjects on GitHub, a small processor, a verified IP block or an FPGA demo show more than marks do.
- Learn the toolsIndustry-grade EDA tools through training programmes, plus open-source tools at home.
- Get industry exposureInternships, live projects and mentors who work in the field.
Key takeaways
- There are design, manufacturing and packaging/test careers, not just "VLSI".
- Verification, physical design and DFT are among the most in-demand design roles.
- Fabs and OSATs are opening roles for mechanical, chemical and materials engineers and for diploma holders.
- Projects and tool experience are what get you hired.
