Own the backend services that handle payment flows and identity checks as a product moves into live production use. The work covers security, reliability, compliance controls and performance, with an emphasis on correctness and recoverability.\nWhat you'll do\n- Build protective controls into the code itself, keeping sensitive card data scope small and covering credentials, permissions, activity records and attack analysis.\n- Manage cloud infrastructure as code, along with automated build and deployment pipelines, staged releases and rollback procedures.\n- Ensure payment authorization, settlement and reconciliation logic is safe to retry, traceable and easy to recover.\n- Set and monitor reliability targets, add instrumentation, prevent outages and write clear operational runbooks.\n- Improve response times on the transaction path and reduce the cost of each transaction.\n- Set architecture direction, write production code and take on-call responsibility for the systems you ship.\nRequirements\nWhat we're looking for\n- Experience building backend systems that other engineers and teams rely on.\n- Solid grasp of keeping operations correct when things fail, including repeat-safe requests, retries, distributed state and failure modes.\n- Everyday safety habits: limiting access to what is needed, handling credentials with care, keeping activity records and anticipating how a system could be attacked.\n- Hands-on experience with cloud infrastructure and infrastructure as code.\n- Proficiency in TypeScript or Python.\n- Clear written communication about incidents, root causes and fixes.\n- Availability to work roughly six days a week, Sunday through Friday.\n- 2 to 5 years of relevant experience.\nBonus points\n- Experience with AWS.\nBenefits\nCompensation and benefits\n- Base salary: USD 140,000 to 300,000 per year\n- Health, dental and vision coverage\nLocation and work model\n- San Francisco, California, United States\n- On-site\n- Roughly 6 days a week (Sunday through Friday), with flexibility on weekends\n-
