SHAPE ECONOMIES.\nAt SGX Group, we create markets. We turn ideas into products and expand access to new opportunities. We are building the future of the exchange in-house: from architecture and platforms to the critical systems that power markets. The biggest decisions are still open to people who join us now.\nThe opportunity\nSGX Group operates Singapore's securities and derivatives exchange. The Core AI Engineer is a senior individual contributor role within the AI & Automation Engineering team, building the shared platform that every SGX AI use case runs on: the enterprise knowledge graph and knowledge-management layer, the governed retrieval and access services above it, and the reusable AI components, tools and APIs that engineers embedded in the business units consume. The platform handles confidential and market-sensitive material, so permission-aware retrieval, encryption and key management, traceable answers and measured quality are product requirements rather than afterthoughts. This is a Singapore-based role.\nWhat you will do\nBuild and operate the core knowledge graph and knowledge-management layer: ontology and metadata model, governed ingestion from enterprise sources, graph projection, and hybrid graph and vector retrieval\nBuild the shared platform features other teams consume: retrieval and access-layer APIs, a tool registry and MCP interfaces, and reusable AI components that stay framework-agnostic so any consuming team can build on them\nMake retrieval permission-aware end to end: sensitivity labels inherited at ingestion, closed-world enforcement where an unlabelled record is denied rather than defaulted, filtering applied inside vector search and graph traversal, and live validation on the sources actually cited\nEngineer traceability and integrity into the platform: citations, transformation lineage from source document to chunk, content hashing and tamper evidence, and an append-only audit of every access decision and write\nOwn encryption and key management for confidential and market-sensitive data: envelope encryption with per-record data keys wrapped by a KMS-held key, authenticated encryption at rest and on the wire, client-side decryption where the service itself must not see plaintext, and key rotation, re-wrapping and revocation\nOwn the evaluation harness: define golden task sets and scoring rubrics, benchmark approaches head to head, and make quality, cost and latency claims reproducible rather than anecdotal\nDesign and implement observability, monitoring and token and cost governance for AI services, and propose fit-for-purpose solutions that optimize business value without overextending the AI budget\nDefine APIs, integration patterns, cohesive architecture, and engineering standards; take designs through Architecture Forum, ARB and InfoSec Release Readiness, and own the resulting technical and governance artefacts\nTurn recurring patterns from business-unit use cases into platform capabilities, and support the engineers who build on them\nLead pre-deployment reviews for medium and high-risk use cases, and technically review work delivered by vendors and partners, reproducing their results in an SGX environment before accepting them\nWhat we are looking for\nEssentials\nProven software engineering experience, including system design, code review, testing practices, debugging in production environments, performance tuning, secure coding, and building reliable, maintainable services\nStrong hands-on coding in Python and TypeScript, and comfort working polyglot, including reading and writing a systems language (parts of the platform are Rust)\nHands-on experience building applications with LLMs: RAG and KAG pipelines, document processing, embeddings and semantic retrieval, and agent and tool integration\nExperience modelling connected data: knowledge graphs, ontology and taxonomy design, entity and relationship extraction, and graph query languages such as Cypher, or deep relational data modelling with a clear appetite to work in graph\nStrong SQL and PostgreSQL, including schema design and query performance, and experience with vector search such as pgvector\nExperience designing and maintaining APIs and shared services that other engineering teams depend on, including versioning and backward compatibility\nStrong applied cryptography: correct use of authenticated encryption such as AES-256-GCM including nonce discipline, envelope encryption with a KEK and DEK split, key management through a cloud KMS or HSM, key rotation and re-wrapping, and careful handling of key material in memory\nAble to threat-model a path that carries secret data and write down what is and is not covered, including where TLS alone is insufficient - such as a TLS-terminating corporate proxy - and what metadata leakage means when the content is market-sensitive\nExperience applying data governance and security controls in regulated environments: data classification, least-privilege access, secrets management with owned rotation, keyless federated credentials, and audit logging\nProven ability to make and document architectural decisions with minimal oversight, and to defend them in an architecture or security review\nComfortable delivering inside a locked-down cloud environment: private-only networking, egress allow-lists, keyless federated credentials, no local container builds, and schema and deployment changes applied under review\nWhat may set you apart\nExperience in financial services, capital markets, or another regulated industry\nFamiliarity with Google Cloud Platform and Vertex AI / Gemini APIs, including Cloud Run, Pub/Sub and Cloud SQL\nNeo4j or another graph database in production, and graph RAG or hybrid graph and vector retrieval\nHands-on with cryptographic libraries and protocols: AEAD constructions, ECDH key agreement such as X25519, HKDF key derivation, Cloud KMS or HSM-backed keys, and Web Crypto for browser-side decryption\nHaving taken an encryption or key-management design through a security review in a regulated firm\nAgent orchestration frameworks and Model Context Protocol (MCP), such as Google ADK, Claude Agent SDK or LangGraph\nEnterprise connector and ingestion work, such as Microsoft Graph / SharePoint, Confluence, and event-driven pipelines\nLLM evaluation practice: LLM-as-judge, deterministic scoring, and regression suites for prompts and models\nBackground in MLOps or AI/ML platform engineering, and effective use of AI coding agents to raise delivery throughput\nVision-language models or document AI for complex document understanding\n About SGX Group\nSGX Group is one of the world's most trusted international marketplaces, known for its stability and openness. Anchored in Singapore, we enable price discovery, capital formation and risk management across asset classes, supported by resilient infrastructure and robust clearing. We convene issuers, investors and intermediaries to create and grow markets that stand the test of time.
