Quantum Error Correction Engineer (Kottayam)

Role summary

We are building a system that implements surface-code quantum error correction with a hardware-accelerated pipeline (multi-FPGA). We already have the FPGA architecture expertise in-house. This role is for a surface-code implementation specialist, someone who understands the surface code deeply and has practical experience with decoder implementations / syndrome-processing pipelines. You will be the person who makes the surface code “real” at the implementation level: transparent algorithmic choices, concrete dataflows, executable reference models, and unambiguous specs that our FPGA team can implement and verify.

What you’ll do
- Own the surface-code implementation plan (algorithm → implementation)
- Define the full syndrome processing + decoding workflow for the chosen surface-code setup
- Identify performance targets: cycle-level latency constraints, throughput requirements, scaling behavior
- Decoder strategy + practical implementation details
- Evaluate or define a decoder approach suitable for real-time/streaming constraints
- Provide implementation-ready descriptions (data structures, update rules, scheduling, approximations)
- Work with the FPGA architect on what belongs in FPGA vs host/control software
- Create implementation artifacts the FPGA team can execute
- Detailed algorithm spec (state machines, message formats, boundary conditions, corner cases)
- Reference implementation in Python/C++ (or similar) to generate expected outputs
- Test vectors + golden models for verification (including fault/noise model assumptions)
- Support integration + validation
- Debug mismatches between reference model and hardware behavior
- Define success metrics (logical error rate targets, latency budget, resource scaling)

Must-have qualifications (non-negotiable)
- Deep working knowledge of surface code QEC beyond textbook level (stabilizers, syndrome extraction, decoding, boundaries/defects or lattice surgery—depending on your approach)
- Hands-on implementatio Apply on Kit Job: kitjob.in/job/4mk5i5
