Career roadmaps

Pick a path. Master it.

Every engineering role looks different up close. Here's what each track actually does, the skills that matter, and a recommended order to learn them.

Frontend Engineer Backend Engineer Full-Stack Engineer Cloud / DevOps Engineer AI / ML Engineer Data Engineer / Analyst Mobile Engineer Systems / Infra Engineer
🎨

Frontend Engineer

Build the interfaces people see every day.

Entry → Senior

Frontend engineers build the visible web — interactive pages, design systems, animations, and the user experience that turns visitors into users.

What you do day to day

  • Translate designs into pixel-perfect, accessible interfaces.
  • Build component libraries and design systems.
  • Optimize page load, interactivity, and Core Web Vitals.
  • Wire frontends to APIs and state management.

Backend Engineer

Build the systems that power every product.

Entry → Staff

Backend engineers design APIs, model data, and own the systems that handle real traffic. Most of the load-bearing work in software lives here.

What you do day to day

  • Design REST and GraphQL APIs for clients and partners.
  • Model relational and document databases.
  • Build background jobs, queues, and event-driven systems.
  • Own performance, reliability, and security of the backend.

Full-Stack Engineer

One engineer. Frontend to database.

Entry → Senior

Full-stack engineers ship features end-to-end — UI, API, schema, deploy. The role of choice at startups and small product teams.

What you do day to day

  • Ship features that span UI, API, and database.
  • Own a product surface area instead of a layer.
  • Make pragmatic stack choices for small teams.
  • Read and write code across every layer comfortably.

Cloud / DevOps Engineer

Make production deploy ten times a day.

Mid → Staff

DevOps and cloud engineers build the infrastructure, pipelines, and observability that let other engineers ship safely. The skill set every team eventually pays for.

What you do day to day

  • Design CI/CD pipelines and release strategies.
  • Provision and operate cloud infrastructure.
  • Containerize and orchestrate workloads.
  • Set up monitoring, alerting, and incident response.

AI / ML Engineer

Ship machine intelligence to real users.

Mid → Senior

AI/ML engineers build, fine-tune, and operate model-powered features — from classical ML models to LLM-driven products with retrieval and tool use.

What you do day to day

  • Build LLM and ML features end-to-end (data → model → API).
  • Design RAG pipelines and prompt infrastructure.
  • Run evals and observability on model outputs.
  • Bridge research-y models with reliable production systems.

Data Engineer / Analyst

Turn raw data into decisions and pipelines.

Entry → Senior

Data engineers build the pipelines, warehouses, and dashboards that the rest of the company uses to make decisions and train models.

What you do day to day

  • Build ELT/ETL pipelines from sources to warehouses.
  • Model warehouses with dimensional modeling and dbt-style transforms.
  • Maintain BI dashboards and reporting.
  • Partner with analysts and ML engineers on feature pipelines.

Mobile Engineer

Build apps that live in pockets.

Entry → Senior

Mobile engineers build native or cross-platform apps with hard constraints — limited memory, offline support, app store reviews, and a UI that has to feel native.

What you do day to day

  • Build React Native or native iOS/Android apps.
  • Integrate with platform APIs (camera, notifications, biometrics).
  • Optimize for battery, memory, and offline experience.
  • Ship to app stores with the gauntlet of review.

Systems / Infra Engineer

Write the software other software runs on.

Mid → Staff

Systems engineers build the low-level pieces — databases, runtimes, schedulers, networking, compilers — that everyone else builds products on top of.

What you do day to day

  • Build performance-critical services and tooling.
  • Work close to the OS — memory, threads, syscalls.
  • Profile and optimize hot paths.
  • Maintain libraries used by hundreds of internal teams.

No matter which path you pick

Four habits that beat any specific stack.

✓

Pick one path first

You can swap later. Compounding beats sampling — most senior engineers earned that title in one area before broadening.

✓

Build the depth, then the breadth

A frontend engineer who understands the backend is paid more than one who only knows React.

✓

Ship things publicly

Side projects, open source, and blog posts beat certifications for almost every hiring manager.

✓

Practice DSA — but only enough to pass

Top-of-funnel interviews still test it. Treat it as a separate skill, not your day job.
