Build the stack with us

We are building chip design tools, verified AI and a GPU, as one stack. We are hiring experienced engineers who want to own a core part of it from day one.

STX-EDA-2614Stalnix EDA

Senior EDA Software Engineer

Experience: 6+ years
Chennai (Navalur), on-site
Full-time

Build the core engines of Stalnix EDA, our RTL-to-GDSII chip design platform: simulation, synthesis, static timing, place and route, and sign-off.

Job description

What you will do

Design and build core engines in one or more areas: HDL simulation (Verilog, SystemVerilog, VHDL), logic synthesis, static timing analysis, placement and routing, or sign-off checks
Write fast, memory-efficient C++ for large designs, with Python for flows and tests
Build HDL parsers, elaboration and netlist data structures
Verify the engines against open-source RTL and reference designs, and compare quality of results with industry tools
Work with our AI team on the EDA co-pilot and with our GPU team, who design with the tools every day

What you bring

6+ years developing EDA software: simulators, synthesis, STA, place and route or verification tools
Strong modern C++ (17/20), data structures and algorithms: graphs, SAT/BDD, optimisation
Solid digital design knowledge: HDL semantics, timing, standard cells
Debugging and profiling large codebases on Linux, with Git

Good to have

Contributions to Yosys, Verilator, OpenROAD, OpenSTA or Icarus Verilog
Formal and equivalence checking
Liberty, LEF/DEF, SDC and GDSII formats
Parallel and multi-threaded computing

Senior AI Engineer, LLMs and Verification

Experience: 5+ years (2+ with LLMs)
Chennai (Navalur), on-site
Full-time

Build Stalnix Super Intelligence, an AI assistant that verifies and fact-checks every answer before it reaches the user, and shows its sources and checks.

Job description

What you will do

Build the assistant on large language models: retrieval, tool use, reasoning and long-context handling

Build evaluation suites and metrics for accuracy, hallucination and source attribution, and run them on every release
Fine-tune and align models, and optimise serving for speed and cost
Work with the EDA team on the chip-design co-pilot

What you bring

5+ years in machine learning engineering, including 2+ years shipping LLM applications
Strong Python and PyTorch
Retrieval-augmented generation, vector search and LLM evaluation in practice
Solid NLP fundamentals and the ability to read and apply research

Good to have

Fact verification or factuality research
Fine-tuning methods: SFT, preference optimisation, LoRA
Inference optimisation: vLLM, TensorRT-LLM, quantisation
Publications or strong open-source work
