Remote, Singapore Codingo Assignments Pte. Ltd. Full time

**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.**

**Job Type**: Contract
Contract length: 3 months

Pay: $1,000.00 - $2,500.00 per month

**Experience**:

- Cryptocurrency: 3 years (preferred)
- Rust (programming language): 3 years (required)
- L1 development: 3 years (preferred)
