Riverflex is partnering with a leading financial institution in the UAE on a strategic Proof of Concept to establish (the foundations of) an AWS data platform. We are seeking a Platform Engineer to own the PoC end-to-end, define the reference architecture, and establish the standards and guardrails that will shape how the data platform is built going forward. This is not a data engineering role. This position is about platform ownership, architecture, governance, and long-term operability. You will serve as the internal authority on “how we do data platforms,” working closely with the partner’s Data Lead and embedded with the on-site platform engineering team to ensure the foundation is robust, scalable, and fit for enterprise-grade analytics and future AI use cases.
Job Responsibility:
Platform ownership & architecture: Own the end-to-end design and delivery of an AWS-based lakehouse Proof of Concept
Act as lead architect and custodian of the data platform, defining reference architectures, reusable patterns, and engineering standards
Design and implement a governed lakehouse architecture using Amazon S3, AWS Glue, Athena, Lake Formation, with Apache Iceberg as a core table format
Governance, security & control: Establish security-first platform designs, including IAM patterns and role-based access, Data access controls, governance guardrails, auditability, etc
Ensure consistent cataloging, lineage, and metadata practices across the lakehouse
Engineering & operability: Build and manage platform infrastructure using Infrastructure as Code (AWS CDK or Terraform)
Ensure the platform is production-minded, with explicit focus on: long-term operability, scalability, cost efficiency and maintainability
Define and implement operational standards, including monitoring, alerting, and basic runbooks where applicable
Collaboration & enablement: Partner closely with the Data Lead to align platform architecture with data engineering and analytics needs
Work embedded with the on-site platform engineering team, acting as a hands-on technical leader and mentor
Document architectural decisions, standards, and operating models to enable reuse and scaling beyond the PoC
Requirements:
6+ years of experience in platform engineering, cloud engineering, or data platform engineering roles
Proven experience owning and shaping platform architectures rather than only implementing pipelines
Deep hands-on experience with: Amazon S3 (storage patterns, lifecycle policies)
Glue (jobs, catalog, orchestration)
Athena
Lake Formation
Apache Iceberg
AWS CDK or Terraform
Strong understanding of AWS Well-Architected Framework and platform best practices
Ability to design for reliability, cost control, and operational simplicity
Architectural mindset and being comfortable operating with reference architectures, engineering standards, guardrails and governance models
Able to balance short-term PoC delivery with long-term platform sustainability
Experience in financial services or other regulated environments is a strong advantage
Ability to be based in the UAE for a minimum of 3 months, working full-time on-site (Abu Dhabi or Dubai)
