SSI Engineering Internship - Lucero Labs
Building the Future of Digital Identity
Duration: Sept-Dec 2025 (4 months, extensible to 6)
Commitment: 20 hours/week, hybrid (Colegiales coworking + remote)
Compensation: $1,000 USD/month + $150 API credits
About Us
Lucero Labs modernizes trust through cutting-edge identity solutions. Our flagship product, Autopen, is a blockchain-backed digital signature platform built on QuarkID for Buenos Aires City. We're Avalanche Foundation-funded and actively moving Argentina on-chain.
Current Impact: Deployed in Buenos Aires universities for attendance control and certificate issuance, processing real-world digital signatures with blockchain verification.
The Challenge
We need to modernize our Self-Sovereign Identity (SSI) stack. Our current QuarkID implementation was built as a proof-of-concept—now we're scaling to serve millions of Buenos Aires residents.
Your Mission: Modernize QuarkID's SSI stack from proof-of-concept to production-grade infrastructure. Evaluate existing frameworks (like Hyperledger's Credo-TS), potentially build custom solutions, and ensure seamless compatibility with Buenos Aires integrations.
What You'll Build
Core Project: QuarkID Stack Modernization
- Research and evaluate modern SSI frameworks (Credo-TS, Veramo, custom solutions)
- Design migration strategy from current proof-of-concept to production architecture
- Implement chosen solution with full Buenos Aires government compatibility
- Contribute improvements to the broader SSI ecosystem
Tech Stack
- Primary: TypeScript/Node.js, Go
- Cryptography: BBS+ signatures, Zero-Knowledge Proofs, digital signatures
- Standards: W3C DIDs, Verifiable Credentials, DIDComm protocol
- Blockchain: Sidetree protocol, Ethereum EVM, Smart Contracts
Focus Areas (Choose Based on Interest)
Architecture Track: Evaluate SSI frameworks, design scalable architecture, build framework-agnostic compatibility layers
Cryptography Track: Upgrade signature schemes, implement selective disclosure and zero-knowledge presentations, optimize mobile performance
Integration Track: Mobile SDK development, government API integrations, high-throughput optimization
Who We're Looking For
Academic Background: Final-year Computer Science, Software Engineering, or related field with solid theoretical foundation
Technical Skills
- Required: TypeScript/JavaScript, Node.js, Git workflows, async programming
- Preferred: Go, React Native, blockchain development, cryptography
- Bonus: Exposure to distributed systems or cryptography
Personal Qualities: Self-directed, strong communicator, growth mindset, impact-driven
Application Process
Step 1: Technical Assessment
Scenario: QuarkID uses custom DID methods that Credo-TS doesn't recognize. You need to implement a resolver.
Your Challenge: Create a prompt to help you:
- Understand DID methods and resolvers
- Learn Credo-TS DID resolution implementation
- Design a custom resolver for QuarkID's DID format
Deliverables:
- AI prompt (300-400 words)
- Analysis (100-150 words): Explain your prompt structure and learning expectations
Step 2: Technical interview + take-home challenge review
Step 3: Paid 1-week trial project ($300)
What We Offer
- Real Impact: Your code serves actual government infrastructure
- Cutting-Edge Tech: Work with technologies 2-3 years ahead of industry
- Open Source Fame: Contribute to major Linux Foundation projects
- Direct Mentorship: Daily standups with CEO, bi-weekly deep dives
- Career Launch: Strong foundation for blockchain/identity career
- Professional Environment: Premium coworking space, flexible hybrid arrangement
