GA Engineer for payment Blockchain Payment Verification

Location: Remote

Type: Full-time / Contract

About the Role

We’re looking for a talented FPGA Engineer to design and implement custom hardware for secure, high-speed payment verification systems leveraging zero-knowledge proofs (ZKPs) and blockchain cryptography.

You’ll work on accelerating cryptographic primitives and verification algorithms for real-time payment infrastructure.

Responsibilities

• Design and implement FPGA architectures for cryptographic and blockchain verification.
• Develop optimized Verilog/VHDL code for digital signal processing, arithmetic units, and cryptographic cores.
• Implement and accelerate zero-knowledge proof primitives (e.g., SNARKs, STARKs, polynomial commitments).
• Integrate FPGA modules into larger payment or blockchain systems.
• Perform synthesis, simulation, and timing analysis using modern FPGA toolchains.
• Collaborate with crypto engineers and protocol designers on performance and security.

Required Knowledge

Candidates should have working or theoretical knowledge of the following algorithms and systems:

• Signature Verification: Ed25519 (Solana transaction validation)
• Hash Functions: SHA-256, SHA-512, Blake3 (used in Proof of History and ledger integrity)
• Zero-Knowledge Proofs: zkSNARKs, zkSTARKs, Bulletproofs
• Elliptic Curve Cryptography: Curve25519, BLS12-381
• Proof Systems: Proof of History (PoH), Merkle Trees for state verification
• Finite Field Arithmetic and modular multipliers implementation in hardware

Qualifications

• Master’s degree or Ph.D. in Computer Engineering, Electrical Engineering, or Embedded Systems.
• Proven experience in FPGA design and verification (Xilinx, Intel/Altera, or Lattice).
• Strong background in digital logic design, timing analysis, and pipelined architectures.
• Hands-on experience with HDL (Verilog/VHDL) and FPGA synthesis tools.
• Solid understanding of cryptographic algorithms and hardware acceleration.

Nice to Have

• Experience with hardware acceleration of ZK proof systems or cryptographic libraries.
• Familiarity with blockchain consensus mechanisms (Solana, Ethereum, etc.).
• Knowledge of hardware-software co-design or embedded cryptography.
• Contributions to open-source FPGA, crypto, or ZK projects.
