Skills guide
Forward Deployed Engineer skills
FDE interviews test a wider surface than product-eng interviews. Half the bar is technical, half is client posture. The great ones also carry a third layer: the discipline to hold context across weeks of ambiguity. Here is the full stack.
Technical skills
- Systems designDesign a service in a room. Explain tradeoffs to a VP. Ship it in a week.
- SQL and data wranglingJoin messy warehouse tables on day one. Notebooks, pandas, DuckDB, dbt.
- Full-stack prototypingShip a working UI against real data in a day. React, FastAPI, Next, or whatever the client runs.
- Platform fluencyKnow your product cold. FDEs at OpenAI live in the API. FDEs at Palantir live in Foundry.
- Debugging in prodRead stack traces on a customer's laptop over Zoom without panic.
- Agent orchestrationDrive a coding agent through discovery, build, and debrief without losing context.
Human skills
- DiscoveryAsk the question the brief avoided. Sit in the awkward silence.
- Executive communicationBrief a VP in three sentences. Write a decision memo a lawyer could read.
- Scope disciplineCut everything that does not prove the loop. Say no politely and often.
- Client postureOwn the room. Be the calmest person when the demo breaks.
- Domain absorptionLearn insurance, defense, or biotech vocabulary in a week.
- Memory disciplineWrite down what was decided and why. Every session. No exceptions.
The third layer: memory discipline
The best FDEs win on one thing: they show up Monday knowing exactly where Friday ended. Notes are structured. Decisions are logged with reasoning. Risks are tracked out loud. Their coding agent is bound to the same discipline, not asked to guess.
That is the whole thesis behind FDEOps: one @fde skill, one folder per engagement, a private fieldbook the agent writes into after every session. Skills without memory decay. Memory without method is a diary.
