Senior Software Engineer - Encryption & PHI at StackAI | LAYIQ

4+ years of experience building and operating production backend systems.
Strong professional experience with Python in a substantial production codebase.
Hands-on experience implementing and operating security-critical product systems, including the code that enforces their guarantees.
Depth in at least one of the following: Encryption and key management
Signing, authentication, sessions, or token infrastructure
Multi-tenant isolation
Sensitive-data processing
Secure storage and runtime use of customer credentials
Practical knowledge of applied cryptography
Experience changing critical systems without disrupting existing customers or making previously stored data inaccessible.
Strong judgment around trust boundaries, failure modes, and the consequences of compromise.
The ability to take an ambiguous technical problem from investigation through production rollout.
You do not need to have worked in every area listed above. We are looking for a strong software engineer with meaningful depth in security-critical systems and the ability to take ownership of adjacent problems.
Prior healthcare experience is helpful but not required. We care more about your ability to understand sensitive-data requirements and turn them into reliable product behavior.
Bonus points
Experience with HashiCorp Vault, cloud KMS products, HSMs, envelope encryption, or key rotation
PHI or PII detection, redaction, pseudonymization, or tokenization
PKI, certificate systems, or cryptographic signing
Multi-tenant SaaS products handling sensitive customer data
Experience in healthcare, payments, identity, financial infrastructure, or another security-sensitive domain
Self-hosted, VPC, on-premises, or air-gapped deployments
AI-agent, LLM, or connector-based application architecture
Startup or growth-stage product experience
How we work
The Core Engineering team owns the systems at the center of StackAI. Engineers take problems end to end: defining the approach, writing the code, planning the migration, and remaining accountable for how the system behaves in production.
The work moves quickly, and decisions are made close to the implementation. We value engineers who can make sound trade-offs under ambiguity, ship durable systems, and continue improving them as the product and its requirements evolve.
As part of Asana, you will be able to draw on established security and infrastructure teams when a problem crosses application and platform boundaries. This role remains embedded in Core Engineering, with direct ownership of the product systems you build.
