    Join Autowhale and Help Redefine Institutional Crypto Infrastructure

     

    Autowhale is building the backbone of institutional crypto trading: a scalable platform that merges execution systems with portfolio and fund managementβ€”serving funds, exchanges, OTC desks, and asset managers. Join us from anywhere and help shape the future of digital asset trading.

     

    What You’ll Own

    • Drive real features: Be responsible for delivering key backend components in areas like DeFi protocols, institutional crypto trading, portfolio management, and analytics pipelines.
    • Build reliably at scale: Design and maintain Python microservices with a strong emphasis on test coverage, observability, performance, and maintainability.
    • Automate everything: Create scripts and tools to streamline our deployment, monitoring, and operations.
    • Shape the codebase: Participate in peer review, define best practices, and help evolve our engineering standards.
    • Flex your autonomy: Own components end-to-endβ€”from specs to deployment.

     

    Tech Stack Snapshot

    • Python (primary), plus optional Rust/Go/C++
    • Web Framework
    • Flask, Web3.py
    • PostgreSQL, MongoDB, timeseries data
    • DevOps
    • Docker, AW S, CI/CD pipelines
    • CCXT
    • RPC Nodes
    • Git, asynchronous patterns, caching

     

    You Bring

    • 3+ years of professional Python experience and delivery of production-grade systems, ideally using microservices.
    • Strong proficiency in data modeling, particularly for financial, time-series, or analytics-heavy workloads.
    • Comfortable with blockchain/Web3 integrationsβ€”e.g., reading on-chain events, token flows.
    • A solid understanding of scalability fundamentals (caching, batching, async, indexing).
    • Excellent communication in English and the ability to work independently in an async-first setup.

       

    What Makes You Stand Out (Bonus Points)

    These aren’t mandatoryβ€”but they’ll help you hit the ground running:

    • Experience in additional languages (Rust, Go, JS, C++).
    • Familiarity with DeFi strategies (e.g., arbitrage, liquidity management) or trading workflows.
    • Prior integration with exchange APIs or financial systems.
    • Understanding of double-entry ledger systems, cross-chain protocols, or multi-chain DeFi.

       

    Why This Role Will Challenge & Reward You

    • 100% Remote + Flexible Hours: Your schedule, your workspaceβ€”plus two regular syncs per week to stay aligned.
    • High Ownership, Low Bureaucracy: We're a tight, transparent teamβ€”no red tape, only impact.
    • Learn the full stack in crypto: From AWS deployments to Web3 pipelines, automated workflows, and trading infrastructure.
    • Competitive compensation: Tailored for mid-senior developers in lower-cost marketsβ€”balance great work and great living standards.
    • Influence from day one: Play a key role in shaping product direction, tooling, and engineering culture.
