Remote, Singapore Codingo Assignments Pte. Ltd. Full time $24,000 - $30,000 per year

Codingo Singapore is the perfect place for student to expand their portfolio

You need a place where you can work on projects that will globalize your standard? Need projects that will expand your knowledge and skills extensively? Looking to find a job in the international spectrum? Codingo Singapore provides you the bridge to the global standard.

Codingo Singapore is Singapore's no. 1 Assignment Help Platform. Initially focusing only in coding, we are now expanding into various fields Thus, we require a lot of manpower to fulfill the fields that we are not established in.

We're building a high-performance Layer-1 inspired by modern BFT chains to power on-chain e-gaming experiences. You'll help us design and ship core protocol and backend components. You must be strong in Rust and have real blockchain development experience (e.g., smart contracts, node/validator work, wallets, or chain integrations).

What you'll do

● Implement and tune BFT consensus and networking for fast finality.

● Build and maintain validator/node software, RPCs, indexing, and wallet logic.

● Ship staking/rewards/referral modules and token-economic mechanisms.

● Integrate verifiable randomness (VRF) for fair gaming outcomes.

● Design safe deposit/withdrawal flows, bridges, and operational controls.

● Stand up real-time oracles for sportsbook data.

● Add safety features (pause/lock, anomaly detection, blacklisting) and support upgrades/testnets.

● Partner with backend/game teams to integrate core chain features.

Must-have skills

● Rust proficiency (required). You've shipped production Rust or substantial OSS in Rust.

● Blockchain development experience (required). Examples: building smart contracts (EVM/Solana/Cosmos/CosmWasm, etc.), contributing to validator/node code, writing wallet/SDKs, or operating nodes.

● Solid grasp of distributed systems fundamentals (consensus, networking, state, performance).

● Working knowledge of applied crypto (keys, signatures), and secure wallet/key handling.

● Product mindset: you write reliable code, instrument it, and iterate with users.

Nice to have

● Exposure to consensus protocols (HotStuff/PBFT) and performance profiling.

● Contributions to L1s (Aptos, Sui, Solana, Cosmos SDK) or similar core-infra projects.

● Experience with oracles, VRF, bridges, multi-sig treasury design.

● Familiarity with on-chain gaming/sportsbook mechanics.

● DevOps for distributed nodes (observability, upgrades, incident response).

Why this role

● Work close to the metal on a modern L1 while shipping real user impact.

● Learn protocol design with mentorship, testnet→mainnet launch exposure.

● Blend protocol engineering with practical product integrations for gaming.

If you're strong in Rust and have shipped meaningful blockchain software, we want to talk—even if you haven't built an L1 end-to-end before.

Contract length: 3 months

Pay: $1, $2,500.00 per month

Experience:

  • Cryptocurrency: 3 years (Preferred)
