As the Software Engineer, you will focus on the cross-layer software development and microservices integration necessary to assemble a highly secure AI inference platform. You will be responsible for: - Wiring multi-module backend layers - Establishing stable inference endpoints - Implementing attestation-gated security mechanisms that safeguard critical model weights and execution boundaries within hardware-enforced Trusted Execution Environments (TEEs) Responsibilities - Multi-Module & Application Integration: Program and stabilize core microservices, bridging backend data pipelines with advanced containerized inference runtimes to ensure seamless data flow. - Secure Endpoint Development: Design, expose, and optimize stable APIs for protected model ingestion, system lifecycle events, and inference requests. - Cryptographic Boundary Assembly: Integrate security sidecars and automated provisioning modules executing asymmetric decryption protocols (e.g., 4096-bit RSA) and cryptographic signature validation to facilitate attestation-gated asset release. - Network & Gateway Routing: Configure low-latency sidecar proxies and API gateways to maintain end-to-end encrypted pathways utilizing strict mutual authentication (mTLS). - Workload Orchestration: Maintain and update cloud-native application configurations (such as Helm charts) to orchestrate isolated container runtimes across distributed execution clusters. Qualifications - Professional fluency in Python, Rust, or C/C++ applied to performant backend services, API frameworks, or system microservices. - Practical experience working with high-throughput inference engines and serving frameworks (such as vLLM or KServe) within containerized environments. - Knowledge of digital certificate management, public key infrastructure (PKI), asymmetric encryption tools (GPG), and transport security protocols (TLS 1.3/mTLS). - Conceptual or practical familiarity with Trusted Execution Environments (TEEs), confidential computing isolation, or remote attestation concepts. - Familiarity constructing continuous integration and continuous deployment (CI/CD) automated pipelines, container orchestration scripts, and automated validation frameworks to facilitate continuous software updates.
