Forward Deployed Engineer
What the work looks like, the stacks behind the title, what each level means and the training that helps, then how interviews run and how to prepare for each step.
What a forward deployed engineer actually does
An engineer who works with the customer, inside their systems, to make the product fit their real needs.
A forward deployed engineer works directly with a company's customers to deploy its product in their environment. They connect it to the customer's data and systems, build the integrations and workflows that are missing, and write production code under real constraints of time, security and access.
The role sits between engineering, product and the customer. Forward deployed engineers spend part of their time with customer teams, on site or remotely, and bring what they learn back to the product team so the product improves for every customer.
More and more teams also work with AI coding tools such as Claude Code, Cursor or GitHub Copilot, and expect engineers to use them with judgment.
- A working session with a customer team on their data and systems
- Building an integration, a data pipeline or a workflow for a customer
- Fixing a blocker in a deployment, often under time pressure
- Feedback to the product team on what customers need
- Time on documentation, security reviews and handover
The title was made popular by Palantir, where forward deployed engineers work inside customer teams. AI companies such as OpenAI and Anthropic now hire for the same role, and so do many data and enterprise software companies.
Depending on the company, the work leans more toward software engineering or more toward customer delivery. The job ad, the share of time spent with customers and the amount of production code you write show where the role really sits.
The same title, very different products
Most forward deployed searches are defined first by the product the company sells, then by the ground every forward deployed engineer shares.
What each level means in practice
Titles vary from one company to the next. What changes from one level to the next is the scope you own and the decisions you take.
- Works on deployments led by a senior engineer
- Learns the product, the customers and their systems
- Builds well-defined integrations with code review
- Leads deployments for smaller customers
- Builds integrations and workflows on their own
- Brings clear feedback to the product team
- Leads complex deployments with large customers
- Takes technical decisions in front of customer teams
- Mentors other engineers and shapes the playbook
- Sets the approach to deployments across customers
- Turns repeated customer work into product features
- Writes the design documents others build on
The paths into the role, and what really counts
Companies look first at systems you have built and deployed with real users. Education and certifications help most early in a career, or to change field.
- Engineering school or master's in computer scienceThe most common path in France, and often expected by large companies.
- University degree in computer scienceThe most common path in the US, at bachelor's or master's level.
- Software engineering firstMost forward deployed engineers start as backend or full-stack engineers before moving closer to customers.
- Solutions or consulting backgroundSolutions engineers and technical consultants with strong coding skills also move into the role.
Our view: for this role, a deployment you led and can walk through, on the customer side and on the code side, often says more than any certificate.
A conversation with a senior tech recruiter
Your first interview is with one of our senior tech recruiters, who knows the role, the stacks and the levels in this guide. The conversation covers your own work through real examples, and the technical exercises come later, with the company. Before the call, we send you the six themes we will cover so you can prepare your examples.
- What you owned yourselfThe deployments, integrations or workflows you were responsible for, and your own part in the team's work.
- Your environment and its constraintsCustomer systems, data access, security rules, deadlines or travel: what shaped your technical choices.
- The decisions you madeWhat to build for one customer and what to bring back to the product, the options you compared and the reasons for your choice.
- The impact of your workWhat changed thanks to your work, with numbers when you have them: time to go live, usage, renewals or incidents.
- How you work with other teamsYour work with customers, sales, product and the core engineering team, and how you settle a disagreement.
- What you want nextThe kind of product, customers and scope you are looking for in your next role.
- Delivery in front of customers
- Speed on unfamiliar systems
- Technical depth and clear communication
- Judgment on what to build
The same ground for every candidate. For a given role, every candidate answers the same final questions, built with the hiring manager around what the role really needs.
Ready for the next steps. After our call, we tell you how the company runs its interviews, who you will meet at each step and what each step is meant to assess.
What the company will assess, step by step
Each company runs its own process, and we walk you through its steps before you start. Forward deployed processes often combine the steps below, and the depth expected at each step grows with your level.
- A coding exerciseLive coding or a take-home on a realistic problem, often with messy data or an API that is new to you.
- A customer scenarioA case or a role play: a customer with a problem and limited time, and how you understand it, decide and build.
- A deep dive on your past workOne deployment or integration you led, discussed in depth: the customer context, your choices and what you would change today.
- Meeting the manager and the teamHow you work, how you take decisions with others and what the team expects in your first months.
- ConfirmedYou solve the problem cleanly, explain each choice in simple words and ask the right questions about the customer's needs.
- SeniorYou lead the discussion, separate what the customer asks for from what they need, and point out risks and limits before you are asked.
- Staff and PrincipalYou run most of the interview as a peer, weigh what should stay custom and what should become product, and connect the case to the wider customer base.
How to prepare as a forward deployed engineer
Practical advice for each step of a forward deployed process, from the way you introduce yourself to the questions you ask at the end of each interview.
Start with the customers and deployments you worked on, their scale and your part in them. Mention your stack in one sentence, then close with what you want next.
For each one, prepare the customer context, the constraints, your decision, the options you set aside, the result and what you would change today. Say "we" for the team and "I" for your own part.
Interviewers often ask how you got up to speed on a system that was new to you. Prepare one concrete example, with the steps you took and the time it took.
In a customer scenario, ask who the users are, what success looks like and which constraints apply before you propose anything. Then explain each choice in plain words.
Part of the role is talking to customer teams outside engineering. Practise explaining one of your systems in two minutes, in plain words, to a customer manager.
Rules on AI coding assistants differ from one company to the next, and sometimes from one step to the next. Ask before each step, and when they are allowed, explain what you ask the tool and how you check its output.
- Tell us about a deployment that went wrong, and what you did.
- A customer asks for a feature the product lacks today. What do you do?
- How do you get up to speed on a system that is new to you?
- Walk us through an integration you built: the data, the APIs and the trade‑offs.
- How much of the time goes to customers, and how much to code?
- How often would I travel, and where?
- How does feedback from deployments reach the product team?
- Who owns the code I write for a customer after the deployment?
- How are deployments staffed, and how long do they last?
- How does the team use AI coding tools day to day?
Where forward deployed engineers come from, and where they go
The roles people most often hold before this one, and the ones they most often move to.
Some forward deployed engineers come from solutions engineering, and some move to product engineering or start their own company.
