Key job responsibilities

Design and implement scalable serverless architectures using AWS Lambda, DynamoDB, SQS, and SNS to support device telemetry, compliance evaluation, and fleet targeting

Own end-to-end delivery of features across 8 production services including KARL (device data warehouse), UEM Platform (greenfield), CMS (claims management), and ACME (device enrollment)

Build new greenfield initiatives for 2026 including ACME v4 (migrating 152K macOS devices to a unified .NET 8 codebase) and OneIT SDK internal components (modular plugin architecture powering the OneIT Desktop Application)

Participate in oncall rotation, triage production incidents, and drive root cause analysis with preventive action items

Collaborate with 40+ consumer teams (FinTech, HR, Infosec, Asset Management) to deliver reliable APIs and data pipelines

A day in the life

You will spend your day designing and shipping features for device management services that run across 4 AWS regions. You will work closely with cross-functional teams including AEA-Core (identity/auth), Client Engineering (deployments), and Helios (software management). A typical week includes sprint planning, code reviews, oncall shadowing, and customer deep-dives with downstream data consumers. You will solve problems at the intersection of device security, fleet orchestration, and large-scale data processing.
