Updated:
Computational Biologist
A Computational Biologist builds reproducible analyses and models that turn genomic, sequence, and structural data into findings whose assumptions, validation, and limits are defensible.
Concepts: 45
Updated:
Cybersecurity Engineer
A Cybersecurity Engineer designs and operates the controls that limit blast radius—identity, network, and data—plus the detection and response paths that catch what gets through.

Updated:
Data Analyst
A Data Analyst builds trusted metrics and analyses that convert ambiguous business questions into defensible decisions for product and operational teams.
Concepts: 18
Updated:
Data Architect
A Data Architect owns the enterprise data model, schema standards, and platform principles that decide how data products are built, governed, and kept reliable across teams.
Concepts: 28
Updated:
Data Engineer
A Data Engineer designs and operates the pipelines, storage, and data models that deliver trustworthy, timely data to the systems and people that depend on it.
Concepts: 27
Updated:
Data Scientist
A Data Scientist builds statistical models and experiments that turn ambiguous business questions into decision-ready evidence, with uncertainty quantified rather than glossed over.
Concepts: 35
Updated:
DevOps Engineer
Builds and owns the automated delivery and infrastructure systems that let a team ship reproducibly, operate securely, and recover without heroics.
Concepts: 25
Updated:
Embedded Systems Engineer
Builds and owns firmware for microcontrollers and real-time embedded products: drivers, interrupt and task timing, and the memory and power budgets that decide what ships.
Concepts: 28
Updated:
Forward Deployed Engineer (FDE)
Embeds with customers to translate ambiguous operational needs into production software, owning discovery, implementation, deployment, reliability, and adoption.
Concepts: 63
Updated:

Builds and owns accessible, performant browser applications, from component APIs and state flow to rendering behavior and production reliability.
Concepts: 27
Updated:
Full-Stack Developer
Builds and owns product capabilities across the client, API, data model, and production path, making sound trade-offs at every boundary.
Concepts: 39
Updated:
Identity and Access Management (IAM) Engineer
Owns the identity layer for humans and services: authentication, least-privilege authorization, and privileged access controls across enterprise systems, kept correct through change and incident.
Concepts: 21
Updated:
MLOps Engineer
Builds and owns the delivery platform that takes a model from dataset to production traffic—training pipelines, model registry, deployment gates, monitoring, retraining, and rollback.
Concepts: 22
Updated:
Machine Learning Engineer
Builds and owns production machine-learning systems: the data and training pipeline behind each model, the serving path that delivers its predictions, and the evidence that it is still correct.
Concepts: 43
Updated:
Network Engineer
Designs, builds, and operates the networks that carry production traffic—from branch and data center to cloud interconnect—with availability targets, segmentation policy, and blast radius as explicit constraints.
Concepts: 16
Updated:
Platform Engineer
Builds and owns self-service developer platforms: paved-road delivery workflows, golden paths, and infrastructure abstractions that let product teams ship safely without running every dependency themselves.
Concepts: 25
Updated:
