Sr. blockchain & distributed systems engineer/developer
MappOptimist Technologies · India
Job Description
We are looking for engineers who don't just write code-they build products, solve difficult engineering problems, and create systems that operate reliably at scale.
This isn't a feature-development role.
This is an opportunity to architect and build the next generation of blockchain infrastructure, trading platforms, De Fi protocols, and intelligent financial systems used by thousands of users.
If you're someone who enjoys solving problems that don't have Stack Overflow answers, we'd love to talk. What You'll Build
You'll design and develop production-grade products such as:
Copy Trading Platforms Real World Asset (RWA) Platforms De Fi Protocols Yield Aggregators Lending & Borrowing Systems Automated Arbitrage Engines Auto-Hedging Platforms AI-powered Trading Infrastructure Smart Money Wallet Monitoring Blockchain Analytics Platforms Trading Bots Cross-chain Applications Institutional Blockchain Infrastructure Wallet & Identity Systems Tokenization PlatformsEvery product is expected to be production-ready, secure, scalable, and built for long-term evolution. Problems You'll Own
This role isn't about completing tickets.
It's about solving engineering problems.
Examples include:
Designing low-latency blockchain transaction pipelines. Building systems capable of processing millions of blockchain events. Architecting highly available backend infrastructure for mission-critical financial applications. Developing blockchain products that continue operating despite RPC failures, network congestion, and chain instability. Building resilient distributed systems that remain reliable under unpredictable workloads. Designing scalable indexing and blockchain data pipelines. Improving transaction execution speed while maintaining correctness and security. Creating infrastructure that engineers enjoy building upon.You'll own the problem—not just the implementation. What Great Looks Like
We're not looking for someone who knows every technology.
We're looking for someone who consistently solves difficult engineering problems.
Exceptional candidates typically demonstrate expertise in several of the following areas. Blockchain
Strong understanding of:
Ethereum Solana Polygon Arbitrum Base Avalanche OptimismAlong with practical experience working with:
Consensus Validators RPC Infrastructure Mempool Gas Optimization Blockchain Networking Cross-chain Communication Transaction Lifecycle Digital Signatures Cryptography Smart ContractsHands-on experience building production-grade smart contracts using:
Solidity Rust Anchor FrameworkExperience with:
Upgradeable Contracts Governance Token Standards Treasury Management Oracle Integration Multi-signature Wallets Vesting Systems Cross-chain Messaging Distributed Systems & Backend EngineeringDeep expertise in at least one modern backend language.
Examples include:
Go Rust Type Script Node.js PythonYou should understand how to build systems that are:
Reliable Observable Maintainable Fault-tolerant Highly available Horizontally scalableExperience with event-driven architecture, Web Sockets, g RPC, distributed messaging, caching, and asynchronous processing is highly valued. Trading Systems
Experience building or working with:
Copy Trading Trading Bots Arbitrage Engines Auto Hedging Liquidity Management Market Making Smart Order Routing Wallet Monitoring Order Execution SystemsUnderstanding of latency optimization and high-frequency transaction processing is a strong advantage. De Fi
Hands-on experience with concepts such as:
AMMs Liquidity Pools Yield Farming Lending Borrowing Vaults Staking Restaking Liquidation Tokenomics InfrastructureStrong understanding of modern engineering infrastructure including:
Docker Kubernetes AWS or GCP Postgre SQL Redis Kafka Rabbit MQ CI/CD Monitoring Logging Performance Optimization SecurityYou understand how blockchain systems fail.
You have experience preventing issues such as:
Reentrancy Flash Loan Exploits Oracle Manipulation Signature Replay Front-running Sandwich Attacks Privilege Escalation Smart Contract VulnerabilitiesSecurity is treated as a product requirement—not an afterthought. AI (Preferred)
We believe AI will fundamentally change how blockchain products are built.
Experience integrating AI into engineering workflows or blockchain products is highly valued.
Examples include:
AI Agents LLM Integration Autonomous Trading Systems Intelligent Automation Predictive Analytics Engineering PrinciplesThese principles guide how we build software.
Build products-not features. Reliability always comes before cleverness. Simplicity scales. Performance is a feature. Measure before optimising. Automate repetitive work. Security is never optional. Every engineer owns the outcome. Strong opinions, loosely held. Great software is built through curiosity, iteration, and craftsmanship. We Care More About What You've Built Than Where You've WorkedDegrees and certifications are appreciated, but they don't define engineering ability.
Show us something you're proud of.
This could be:
Production products Git Hub repositories Smart contracts Open-source contributions Technical blogs Research Architecture documents Conference talks Hackathon projects Engineering write-upsExceptional work speaks louder than resumes. Our Interview Process
We don't ask trivia questions.
Instead, we'll discuss:
Products you've built Engineering decisions you've made System architecture Production incidents you've solved Trade-offs you've considered Scaling challenges you've faced Technical problems you're most proud of solvingExpect conversations, not interrogations. Before You Apply
Please include:
Resume Git Hub Profile Linked In Profile Portfolio (if available) Live Products Smart Contract Repositories Open Source Contributions Technical Blogs (optional)Applications that demonstrate real engineering work will always stand out more than keyword-heavy resumes.
We're building products that push the boundaries of blockchain, distributed systems, and intelligent financial infrastructure.
If that excites you, we'd love to hear from you.
