Senior Backend Engineer – Secure Data Gateway

We’re building a next-generation healthcare automation platform that separates sensitive data into a secure enclave while enabling rapid product development everywhere else.
You’ll lead the backend development of that secure enclave — designing the tokenization, encryption, and compliance layer that keeps PHI safe while the rest of the system moves fast.

What You’ll Do

• Design and build a secure AWS enclave using Lambda, Step Functions, Aurora, and S3 Object Lock.
• Develop a policy-enforced gateway API that exposes tokenized identifiers and minimum-necessary data.
• Implement idempotent integrations and message queues for reliable data exchange with clinical systems.
• Create and maintain tokenization/pseudonymization services and break-glass access procedures.
• Set up auditing, monitoring, and compliance evidence (KMS keys, IAM policies, DR drills).
• Collaborate closely with frontend and orchestration teams to define boundary contracts and testing standards.

What We’re Looking For

• 5+ years of backend or cloud engineering experience.
• Proven hands-on work with AWS serverless (Lambda, Step Functions, EventBridge, DynamoDB, Aurora).
• Strong grasp of data security, IAM least privilege, and HIPAA/HITECH compliance.
• Proficiency in Python or TypeScript and building audited, well-structured APIs.
• Experience designing tokenization or privacy-preserving data flows.
• Bonus: familiarity with healthcare integrations or FHIR, Terraform/CDK, SOC2 evidence prep.

Why This Role Matters

You’ll be responsible for the trust foundation — the layer that allows the entire product to operate safely, compliantly, and at startup speed.
