• Design systems for high-volume ingestion, processing, search, analytics, and AI workloads.
• Own decisions around service boundaries, APIs, storage, caching, queues, and asynchronous processing.
• Co-own architecture decision records, ensuring significant choices have written reasoning and more than one signer.
• Set technical standards through design reviews and practical examples.
• Handle escalations involving production correctness, performance, reliability, and architecture.
• Work with Site Reliability Engineers on availability, recovery, observability, and isolation guarantees.
• Help tech leads and senior engineers develop their technical judgment.

• Hands-on knowledge of authentication, authorisation, role-based access control, tenant isolation, encryption, auditability, and enterprise security requirements.
• Experience architecting production AI/LLM components, including model abstraction, asynchronous inference, evaluation, versioning, cost controls, and traceability.
• Experience designing systems with guarantees around immutability, traceability, and reproducibility, with clear reasoning behind the trade-offs.
• Ability to make and defend architectural decisions involving cost, complexity, and operational risk.
• Ability to challenge a founder or Head of Engineering through written, evidence-based reasoning.
• The stack includes TypeScript/Node.js, Python, PostgreSQL with pgvector, OpenSearch, Redis, GCP, Kubernetes/GKE, Docker, and AI/LLM infrastructure.

• Strong fundamentals in distributed systems, databases, cloud architecture, and production engineering matter more than a particular framework.

Preferred

• Experience in regulated or externally audited environments.
• Experience with cryptographic integrity, including signing, chaining, and verification.
• Experience with AI/LLM components in the critical path.
• Experience handling technical escalations for enterprise customers.
• A previous Staff or Principal Engineer role at a company of a similar stage.
