Founding Backend Engineer

As the Founding Backend Engineer, you will own the systems that move payments and assert identity for Lane as it goes from a working platform to real production traffic. A retry that runs twice is a double charge; a leaked credential is a breach. The codebase is relatively mature, so the work now is the production layer: security, anticipating scale, catching bad actors, technical compliance and meeting SLAs. You will work closely with Lane’s two existing backend engineers, with a horizontal focus on security, compliance and scalability rather than one product area. This is an IC role: you set the architecture, write the code and carry the pager for what you ship. This role is in person at Lane’s San Francisco office, roughly 6 days a week (Sunday through Friday), with flexibility on weekends.

You will directly

• Build security and compliance into the code: small PCI scope, secrets and key management, access control, audit trails, SOC 2 / PCI DSS controls as checks, threat modeling, incident response
• Run the AWS platform as infrastructure as code, plus CI/CD, staged rollouts and rollbacks
• Keep payments correct: authorization, capture and reconciliation that are idempotent, auditable and recoverable
• Own reliability: SLOs, instrumentation, outage prevention and runbooks someone can follow at 2 a.m.
• Drive efficiency: latency on the purchase path and cost per transaction
