About the role
This role owns the software and cloud-native architecture of AI-enabled applications and retrieval systems, from design to production. It combines architectural leadership with hands-on engineering: designing GenAI and RAG solutions, building cloud-native backend services, and ensuring the security, reliability, and observability required for production workloads.
Requirements
What you will do
Design scalable, secure, and resilient architectures for AI-enabled applications, defining service boundaries, data flows, APIs, and integration patterns.
Define cloud-native patterns across microservices, containers, serverless, and event-driven systems.
Design and productionize GenAI and RAG solutions: model selection and routing, retrieval strategy, evaluation, guardrails, and cost/latency optimization.
Build backend services in TypeScript/Node.js and/or Python, and event-driven workflows with queues, workers, and webhooks.
Define non-functional requirements, evaluate trade-offs, and document decisions in ADRs.
Translate business use cases into technical designs, assessments, and executive summaries.
Own the architecture from discovery to go-live, guiding engineers through architecture and code reviews.
Implement observability and secure CI/CD pipelines.
Job requirements
7+ years of software engineering experience.
Proven experience owning the architecture of production distributed systems (microservices, domain-driven design, REST and asynchronous APIs).
Hands-on delivery of production GenAI or LLM applications, including evaluation and AI safety controls.
Experience with RAG, embeddings, and vector databases (pgvector, OpenSearch, or equivalent).
Strong TypeScript/Node.js or Python engineering experience.
Deep knowledge of cloud-native patterns: containers and Kubernetes, serverless, event-driven messaging, and resilience patterns.
Strong understanding of security in cloud-native systems: identity, authorization, secrets management, and data protection.
Docker, CI/CD, automated testing, and observability (OpenTelemetry, Grafana, Datadog, or CloudWatch).
Nice to have
