Teams at StackAI

Build and operate security-critical backend systems in Python, including encryption, key management, sensitive-data controls, credential protection, tenant isolation, authentication, signing, and token handling. Own projects end to end from investigation and architecture through implementation, migration, staged rollout, observability, and recovery. The role requires applied cryptography, strong trust-boundary judgment, and experience safely evolving systems handling sensitive or regulated data across cloud, VPC, and on-premises deployments.

The Business Development Representative will generate qualified leads through outbound prospecting, facilitate meetings for AEs, and build relationships with potential customers.

Own and evolve the durable execution engine for AI agents: runtime, scheduling, checkpointing, resumption, and recovery. Ensure correctness, scalability, reliability, and ecosystem extensibility while shaping execution models and operating the engine in production under heavy load.
