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 management—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-end—from specs to deployment.

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 integrations—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 mandatory—but they’ll help you hit the ground running:

• 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 workspace—plus two regular syncs per week to stay aligned.
• High Ownership, Low Bureaucracy: We're a tight, transparent team—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 markets—balance great work and great living standards.

• Influence from day one: Play a key role in shaping product direction, tooling, and engineering culture.
