Marcus Lindberg
Senior Blockchain Engineer - Low-Latency Execution Infrastructure (HyperEVM / Hyperliquid)
Full time
Remote
we’re looking for a senior blockchain engineer to build low-latency execution infrastructure around hyperevm and hyperliquid-related trading systems.
this is not a frontend or dapp role. the focus is on real-time execution systems, chain-native infrastructure, and market-aware backend engineering where latency, ordering, and state correctness directly impact execution outcomes.
you will work on systems that operate under noisy, adversarial, and highly dynamic conditions, including delayed or missing websocket events, rpc inconsistencies, transaction lifecycle complexity, state desynchronization, retries, and recovery logic.
core responsibilities include building and maintaining realtime blockchain data pipelines, websocket and rpc streaming systems, execution orchestration layers, liquidity-aware routing logic, transaction lifecycle management, and integration with orderbook and market data systems.
we are specifically looking for engineers who think in systems rather than features. meaning understanding how data flows through pipelines, how state evolves over time, how failures propagate, and how to design systems that recover automatically without manual intervention.
areas of work include:
- realtime blockchain data ingestion
- mempool-aware execution flows
- transaction lifecycle handling
- execution sequencing and routing
- websocket and rpc infrastructure
- state synchronization systems
- liquidity and orderbook integration
- performance and latency optimization
you should be comfortable working with distributed systems, asynchronous event processing, and latency-sensitive backend architectures.
strong experience in one or more of the following areas is highly relevant:
- exchange infrastructure
- trading systems
- execution engines
- blockchain indexers
- realtime event systems
- arbitrage systems
- rpc/node infrastructure
- defi backend systems
- low-latency backend engineering
preferred technical stack:
- typescript / node.js
- go
- rust
- python
- postgres
- clickhouse
- redis
- kafka or similar messaging systems
- docker
- linux environments
- evm rpc internals
- websocket infrastructure
ecosystem familiarity:
- ethereum, arbitrum, base, optimism, bsc
- hyperliquid / hyperevm
- foundry
- ethers.js / viem
- geth / erigon / nethermind
- dex and amm mechanics
- liquidity math, slippage, gas strategy, routing logic
this role is not suitable for:
- frontend-only developers
- nft or basic dapp experience only
- tutorial-level web3 developers
- candidates without production systems experience
we value engineers who have built real systems where correctness, latency, and reliability matter under load. we care less about buzzwords and more about concrete systems you have personally built and operated.
ideal candidates can clearly explain:
- system architecture decisions
- bottlenecks and tradeoffs
- failure modes and recovery strategies
- latency considerations in real systems
- production debugging experience
working style:
- remote
- async-first
- low bureaucracy
- high ownership
- engineering-driven team
- direct technical communication
we strongly prefer practical engineering depth over polished presentation. if you have built or worked on systems involving realtime data, trading infrastructure, blockchain execution, or latency-sensitive backend systems, please include details of those systems when applying.

Software Engineer (Python)
Taipei, Taiwan
Taipei, Taiwan
Full time
Office
Our client is seeking a backend engineer to assume full responsibility for core functionalities on their medical imaging platform. In this role, you will not just hand off your code at the pull request stage but will be directly accountable for system accuracy, production stability, and the security of clinical data that impacts patient care directly.
The data science team creates machine learning models; your task is to create the robust, deterministic platform that supports them. Your responsibilities will include designing scalable architectures, resolving concurrency issues, ensuring seamless data migrations without downtime, and ensuring the stability of legacy services as their replacements are developed.
Responsibilities:
Full ownership of the technical roadmap of our Python/FastAPI ecosystem, encompassing API design, background task distribution, and production observability.
Manage and develop our PostgreSQL schema in terms of data integrity and persistence, including migrations, lock mechanisms, query optimization, and multi-tenant data isolation while adhering to HIPAA/PHI compliance.
Design and implement resilient image processing pipelines for handling intensive medical imaging files in asynchronous, event-driven workflows from ingestion and de-identification to model inference and result delivery.
Establish reliable API interfaces with frontend teams and clear model input/output contracts with data scientists to ensure a smooth cross-functional collaboration.
Keep thorough technical records, oversee the transition of legacy systems, and maintain Architecture Decision Records (ADRs).
Requirements:
Minimum of 5 years of software engineering experience with demonstrated production ownership and deep expertise in systems and backend fundamentals.
Proficiency in concurrency and distributed systems with a strong understanding of race conditions, deadlocks, idempotent processing, and messaging failure modes.
Hands-on experience with PostgreSQL internals and message brokers in a production environment.
Strong commitment to typed code, automated testing, CI/CD pipelines, Docker, and modern AI developer tools.
Ability to challenge requirements, set technical standards, and communicate effectively in both English and Chinese.
Nice-to-have Skills:
Familiarity with operating containerized workloads on Google Cloud Platform.
Direct experience with medical imaging workflows, DICOM standard protocols, or healthcare regulatory frameworks.
Knowledge of multi-tenant database patterns or deploying hybrid cloud/on-prem solutions.
Exposure to scientific computing contexts like NumPy, computational geometry, or frontend technologies like React/TypeScript.
Certain AI tools may be utilized in the hiring process for tasks such as application review and assessing candidate materials. These tools assist but do not replace human judgment, with final hiring decisions being made by humans. For more information on data processing, please contact us directly.
