SSE - Physical Asset Digitization & Security (Ramapuram)

Job Title: Senior Software Engineer (Physical Asset Digitization & Security)<\/span> <\/b> <\/p> Location:<\/span> <\/b> Chennai<\/span> <\/p> Employment Type:<\/span> <\/b> Full -Time<\/span> <\/p> The Prospect<\/span> <\/b> <\/p> We are an advanced technology company building the next generation of Phygital (Physical -to -Digital) Authentication<\/b>. Our platform establishes an immutable link between physical goods and digital records, ensuring provenance and authenticity in high -stakes environments.<\/span> <\/p> We are seeking a Senior Software Engineer<\/b> with a systems thinking mindset to architect the backbone of our verification ecosystem. You will be responsible for designing the secure pipelines that ingest real -world hardware data, normalize it, and anchor it permanently to a blockchain ledger.<\/span> <\/p> <\/span> <\/p> Role & Responsibilities<\/span> <\/b> <\/p> 1. Core Backend & Architecture<\/span> <\/b> <\/p>
- Design and implement high -performance APIs that act as the bridge between industrial hardware and our cloud infrastructure.<\/span> <\/li>
- Build the Ingress Normalization Engine<\/b>: A critical service that takes raw, noisy data from field sensors (IoT/Handhelds) and converts it into standardized, comparable digital formats.<\/span> <\/li>
- Develop logic for Fuzzy Matching and Tolerance Scoring<\/b>: You will write algorithms that compare field -captured metrics against a "Golden Record" stored on -chain, determining authenticity based on configurable pass/fail thresholds.<\/span> <\/li> <\/ul> 2. Blockchain & Data Integrity<\/span> <\/b> <\/p>
- Implement Smart Contracts<\/b> (or chain -code) to store unique Asset Fingerprints and immutable audit logs.<\/span> <\/li>
- Design cryptographic anchoring workflows where physical item data is hashed and timestamped to provide tamper -evident proof of existence.<\/span> <\/li>
- Ensure zero -knowledge privacy patterns where necessary: storing proofs on -chain while keeping sensitive parametric data in off -chain secure enclaves.<\/span> <\/li> <\/ul> 3. Secure Device Integration<\/span> <\/b> <\/p>
- Architect the Identity Gateway<\/b> that manages secure sessions between consumer mobile devices and proprietary hardware tags.<\/span> <\/li>
- Implement challenge -response protocols (Nonces) to prevent replay attacks and ensure that every physical interaction (scan/tap) is cryptographically unique.<\/span> <\/li> <\/ul> <\/span> <\/div> Technical Qualifications<\/span> <\/b> <\/p> Required Skills (Must Haves)<\/span> <\/b> <\/p>
- Backend Proficiency:<\/span> <\/b> 4+ years of experience in Go, Rust, or Node.js<\/b>. You understand concurrency, memory management, and how to build low -latency services.<\/span> <\/li>
- Blockchain Integration:<\/span> <\/b> Solid experience with Web3 libraries (ethers.js, web3.py)<\/b> and writing/interacting with smart contracts (Solidity/EVM). You know the difference between storing data on -chain<\/i> vs. storing a hash<\/i> on -chain.<\/span> <\/li>
- Data & Algorithms:<\/span> <\/b> Strong background in handling numerical data arrays. Experience with normalization, precision rounding, and statistical comparison<\/b> (e.g., comparing two slightly different datasets to find a match) is critical.<\/span> <\/li>
- Security Standards:<\/span> <\/b> Deep understanding of PKI, SHA -256 Hashing, and Digital Signatures<\/b>. You know how to secure an API endpoint against spoofing.<\/span> <\/li> <\/ul> Preferred Qualifications (Nice to Haves)<\/span> <\/b> <\/p>
- IoT / Hardware Interface:<\/span> <\/b> Experience working with Serial/USB data streams<\/b> or parsing raw output from industrial equipment (scanners, sensors, or metrology devices).<\/span> <\/li>
- Mobile Protocols:<\/span> <\/b> Familiarity with NFC (Near Field Communication)<\/b> standards, NDEF payload structure, and mobile deep -linking.<\/span> <\/li>
- Cloud Infrastructure:<\/span> <\/b> Hands -on experience with AWS/GCP<\/b> serverless architectures (Lambda/Functions) and event -driven message queues (Kafka/SQS) for handling audit logs.<\/span> <\/li> <\/ul> <\/span> <\/div> What We Look For (The "Soft" Skills)<\/span> <\/b> <\/p>
- Ambiguity Tolerance:<\/span> <\/b> You can look at a requirement like "Make sure the field scan matches the database record" and ask the right questions: What is the acceptable variance? How do we handle network latency?<\/i> <\/span> <\/li>
- Security Mindset:<\/span> <\/b> You assume the hardware is in an adversarial environment. You design systems that trust no single input without cryptographic verification.<\/span> <\/li>
- Documentation:<\/span> <\/b> You write clear RFCs and API specs, knowing that this system will become a reference standard for third -party auditors.<\/span> <\/li> <\/ul> <\/div> <\/span> Apply on Kit Job: kitjob.in/job/4lv34p
