Senior Python Engineer — Data & Detection

Key Responsibilities

• Data Ingestion at Scale: Design, build, and operate pipelines that ingest large volumes of telemetry from mobile endpoints reliably and efficiently.
• ETL & Detection Pipelines: Build and maintain the ETL processes that transform raw data, and implement the detection logic that runs across it to surface threats.
• Forensic Artefact Extraction: Architect the extraction and parsing of complex data from mobile forensic artefacts, handling the varied and often undocumented structures these artefacts contain.
• Partnering with Research: Work closely with the research team to implement their prototypes in production, translate their detection ideas into robust pipeline logic, and build the data access and tooling they need to uncover mobile spyware.
• Scalability & Reliability: Ensure the data platform performs at scale, optimizing throughput, query performance, and cost across large datasets, with strong reliability and fault tolerance.
• Data Quality & Observability: Build monitoring, validation, and error-handling into the pipelines so data issues are caught early and the system is observable end to end.

Day-to-Day Activities

Requirements

• 5+ years of backend engineering experience, with strong Python skills

• Hands-on experience deploying and operating services on AWS (Fargate, EC2, Serverless/Lambda) or the equivalent on GCP or Azure
• Solid understanding of data modelling, pipeline design, and performance optimization
• Experience building reliable, observable, fault-tolerant systems in production
• Strong problem-solving skills and comfort working with messy, real-world data
• Ability to collaborate closely with non-engineering teams and turn prototypes into production systems
