We build a connected-worker platform for large construction and industrial sites. Smart helmets, anchors, and gateways feed a real-time SaaS platform that supports worker location, safety compliance, automated mustering, and productivity analytics across major GCC projects.\nAbout the role:As Principal Platform Engineer, you will be the senior individual contributor accountable for the platform's technical integrity. You will set architecture, make critical implementation contributions, and lead across boundaries through design quality and earned technical trust.\nThis is not an engineering-management role. You will not own hiring, performance cycles, or sprint administration. You will mentor engineers, establish contribution standards, unblock hard technical work, and partner with engineering management and Product on sequencing and team health.\nWhat success looks like - first 6 months:You understand architecture, ownership boundaries, open decisions, and production risks deeply enough to lead a walkthrough of any core platform area.\n\nThe most consequential platform decisions are captured in clear architecture decision records, with explicit trade-offs and evidence.\n\nThe AIP layer - including agent runtime, MCP surface, and AI-powered product capabilities - has a coherent technical direction and at least one production-shaped vertical slice.\n\nThe contribution standard is operational: scoped issues, reviewable changes, clear component boundaries, reliable tests, and links between implementation and architecture.\n\nYou have delivered a material platform capability or de-risked a major architectural uncertainty through working software and measurable validation.\n\nEngineering, Product, Hardware, Field Engineering, and leadership trust your technical judgment and understand the platform direction.\n\nWhat you will own:Architecture across ontology and semantics, governed pipelines and lineage, streaming and data sources, SDK and API surfaces, authorization and governance, application services, and release infrastructure.\n\nArchitecture decision records for consequential platform choices, revisiting old decisions when evidence or implementation pressure indicates a better path.\n\nThe technical direction of WC3's AI-native capabilities, including agent runtime design, MCP interfaces, retrieval, tool use, output evaluation, and responsible-AI controls.\n\nEngineering standards that allow multiple contributors and teams to change the platform safely.\n\nWhat you will do:Design and implement production capabilities across the stack, spending substantial time in code, prototypes, reviews, debugging, and system validation.\n\nDefine and evolve domain models and ontology patterns that connect workers, devices, sites, events, rules, and customer workflows.\n\nDesign governed data pipelines with clear contracts, lineage, replay behavior, quality checks, and operational ownership.\n\nBuild secure, stable API and SDK surfaces for internal teams, partners, customers, and AI agents.\n\nMake pragmatic data-store choices across relational, time-series, streaming, search, and vector workloads.\n\nDrive the current C#/.NET backend while reasoning credibly across Go, Python, Java, Node.js, and TypeScript when the product requires a different trade-off.\n\nRaise engineering maturity through automated testing, CI gates, release safety, observability, service-level objectives, incident learning, and migration discipline.\n\nEmbed security and compliance into design and implementation, including data residency, encryption, audit logging, access control, tenant isolation, and responsible-AI guardrails.\n\nMentor senior engineers, review designs and code, create reference implementations, and help contributors earn ownership of platform areas.\n\nCollaborate with Product, Hardware, Field Engineering, customers, and partners to connect architecture choices to real site outcomes.\n\nWhat you will bring:10+ years of software engineering experience, including sustained impact at Staff, Principal, Lead Architect, or equivalent senior individual-contributor scope.\n\nA track record of designing and delivering scalable, multi-tenant SaaS platforms or large distributed systems in production, including incidents, migrations, and scaling failures.\n\nExperience owning a platform across its lifecycle from architecture and implementation through deployment, operation, and evolution.\n\nDeep backend and distributed-systems judgment, with strong hands-on ability in at least one of C#/.NET, Go, Python, Java, or Node.js and credible range across others.\n\nStrong API design skills across REST and/or GraphQL, OpenAPI or SDK code generation, and secure identity patterns such as OAuth 2.0, JWT, and SSO.\n\nCloud and delivery experience with GCP and/or AWS, containers, Kubernetes, Terraform, CI/CD, observability, and production operations.\n\nExperience with ontology-driven or governed platforms such as Palantir Foundry/AIP, Databricks Unity Catalog, or equivalent first-principles work with ontologies, pipelines, lineage, governed SDKs, and applications.\n\nHands-on experience with LLM integration patterns such as prompting, retrieval, tool or function calling, MCP, agent runtime design, and output evaluation.\n\nPrincipal-level influence through technical writing, architecture facilitation, mentorship, and alignment without direct authority.\n\nExceptional written and spoken English, including precise issues, ADRs, design documents, reviews, and stakeholder communication.\n\nNice to have:Direct, hands-on Palantir Foundry and/or AIP experience on a live production surface.\n\nAgentic frameworks, multi-agent orchestration, or durable workflow systems.\n\nIoT or connected-device ingestion, device-to-cloud communication, and high-volume event processing.\n\nEnterprise integrations including identity providers, ERP systems, project-management platforms, Oracle, or Procore.\n\nWhat we offer:The companyPrincipal Platform Engineer\nAl Khobar, KSA | Full-time | Principal individual contributor | Reports to VP Engineering\nAbout the CompanyThe company is a construction-technology company headquartered in Al Khobar, KSA.
