Beyond our core stack, we care more about strong engineering fundamentals, curiosity, and the ability to learn quickly than about any specific technology.\nYou'll thrive in this role if you:\nHave strong production experience building backend services in Python (FastAPI or similar).\nHave built real-time or streaming data systems - message queues, WebSockets, time-series data - and enjoy hard distributed systems problems.\nHave owned a production system end to end - designed it, shipped it, and fixed it when it broke.\nAre eager to learn new technologies and adapt to new technical domains.\nCare deeply about reliability, security, and scalability.\nGet real leverage from AI coding tools, with a considered view on what to delegate to them and what not to.\nCommunicate well and enjoy collaborating across teams.\nExperience in any of the following is a plus:\nBuilding geospatial or 3D data visualizations in TypeScript and React.\nEdge computing, or moving data reliably over constrained or unreliable networks.\nAzure or another major cloud platform.\nHardware, sensors, robotics, telemetry, or defense systems.\nRequirements\nMust be a U.S. Person (U.S. citizen or permanent resident), as required for access to controlled technology.\nAbility to obtain and maintain a U.S. security clearance.\nBased in, or willing to relocate to, the San Francisco Bay Area. This role is onsite in our SF office.\n\nWhy CHAOS?\nHealth Benefits: Medical, dental, and vision benefits 100% paid for by the company\n Additional benefits: 401k (+ 50% company match up to 6% of pay), FSA, HSA, life insurance, and more\nOur Perks: Free daily lunch, ‘No meeting Fridays’, unlimited PTO, casual dress code\n Compensation Components: Competitive base salaries, generous pre-IPO stock option grants, relocation assistance, and (coming soon!) annual bonuses\nTeam Growth: 250 employees and counting across 5 global offices\n Salary Range: $190,000 - $260,000\nThe stated compensation range reflects only the targeted base compensation range and excludes additional earnings such as bonus, equity, and benefits. If your compensation requirements fall outside of the range, we still encourage you to apply. The salary range for this role is an estimate based on a range of compensation factors, inclusive of base salary only. Actual salary offer may vary based on (but not limited to) work experience, education and/or training, critical skills, and/or business considerations. \nRecruiting Agencies: CHAOS Industries does not accept unsolicited resumes or outreach.
