Why Do Forward Deployed Engineers Travel?

Forward Deployed Engineers travel because the core premise of the role building and owning a system inside a customer's actual environment often can't be done remotely. Security requirements, airgapped systems, and the need to understand real workflows firsthand mean the engineer has to go to where the problem actually lives, not the other way around.

That's not incidental to the job. It's baked into the name. "Forward deployed" is borrowed directly from military doctrine, where forward-deployed forces operate close to the point of action instead of from a distant base. The FDE model applies that same logic to software: instead of building in isolation and shipping to a customer, the engineer goes to the customer.

This is one of the most-asked questions from engineers actually considering the role not because travel is a minor logistical detail, but because it materially shapes what day-to-day life in the job looks like. This guide covers where the requirement comes from, why it exists for genuinely practical reasons rather than tradition alone, how much travel actually looks like across different companies and industries, and how to think about whether it's a fit for you specifically.

The Military Origin of "Forward Deployed"

The phrase didn't originate in tech. In military doctrine, forward-deployed forces are positioned close to where action actually happens, rather than staged at a distant home base faster response, direct situational awareness, no lag between decision and execution.

Palantir borrowed that logic when it pioneered the FDE model for enterprise and government software. The company found that even simple product demos for intelligence and defense customers could require weeks of NDAs, clearances, and access approvals before an engineer could so much as see the target environment. The only way to actually build something that worked was to go where the problem was, get the approvals, and sit next to the people who'd use it.

That origin story explains why travel isn't an unfortunate side effect of the FDE role; it's close to the entire reason the role exists in its original form.

Why On-Site Presence Actually Matters

Strip away the military framing, and a handful of concrete, practical reasons explain why remote work often can't replace physical presence for this specific job.

Security, Compliance, and Airgapped Systems

Some of the most sensitive deployments are defense, intelligence, critical infrastructure, and regulated financial systems run on airgapped networks that are physically disconnected from the outside internet by design. There's no remote-access workaround for a system that was deliberately built not to have one.

Former Palantir FDE Anjor Kanekar has described working on the final assembly line at aerospace manufacturer Airbus, and noted that many of his peers worked in similarly unconventional, sometimes airgapped environments. That's not an edge case for this category of work, it's a fairly normal one.

Understanding the Real Environment, Not the Idealized One

A customer's actual workflow rarely matches how it's described on a call. Being physically present lets an FDE see:

• The messy, undocumented workarounds employees actually use day to day
• Which systems genuinely talk to each other, versus which ones are supposed to but don't
• The real friction points a remote discovery call would never surface

Industrial AI startup Matta puts this bluntly in its own hiring language, expecting FDEs to scope out solutions directly on the factory floor not from a conference room describing it secondhand.

Building Trust With Stakeholders Who've Seen Vendors Fail Before

Enterprise buyers, especially in regulated industries, have usually been burned before by a vendor who oversold a demo and disappeared after the contract was signed. Physical presence is a credibility signal that a video call can't fully replicate; it shows the vendor is willing to be accountable in the room, not just on a slide.

That trust-building matters most with the stakeholders who aren't technical: the compliance officer, the operations lead, the frontline staff who'll actually use the system. They're rarely won over by an architecture diagram alone.

Debugging and Fixing Issues That Can't Be Solved Remotely

Production issues inside a customer's own infrastructure sometimes require physical access, a badge to enter a facility, a workstation inside a secured network, or simply being present when something breaks so it can be diagnosed in real time rather than reconstructed after the fact from logs.

Faster Iteration and Reduced Integration Risk

Being embedded on-site shortens the feedback loop dramatically. A question that would take three days to resolve over email waiting on the right stakeholder, waiting on access approval often gets answered in the same afternoon when the FDE is sitting a few desks away from the person who knows the answer.

How Much Do Forward Deployed Engineers Actually Travel?

Travel intensity varies significantly by company, industry, and customer type; there's no single universal number, but a consistent range shows up across the companies running FDE programs.

The general pattern: government, defense, healthcare, and industrial deployments skew toward the higher end. AI-lab and SaaS-vendor FDE roles tend to run hybrid, with travel concentrated around kickoffs, critical milestones, and periodic on-site stretches rather than constant presence.

Travel Expectations by Industry and Deployment Type

A few consistent patterns show up in why travel intensity differs so much across sectors:

• Government and defense deployments often involve classified or airgapped environments where remote access simply isn't an option, pushing travel toward the highest end of the range.
• Healthcare deployments frequently involve sensitive patient data and strict compliance requirements that favor on-site work, at least during the integration and go-live phases.
• Industrial and manufacturing deployments (factory floors, assembly lines) require physical presence simply because the systems being integrated with are physical machinery, not just software.
• AI labs and SaaS vendors increasingly run hybrid models heavier travel during discovery and go-live, lighter travel once a system stabilizes and moves into steady-state monitoring.

For a closer look at how these expectations actually show up in job postings, the specific phrases and percentages companies use for the Forward Deployed Engineer job description breaks down that language line by line.

How Travel Expectations Are Shifting as the Role Evolves

Travel intensity for FDEs isn't fixed forever; it's shifting as the tooling available to the role changes. AI-assisted development has measurably compressed how much on-site time some deployments actually need: work that used to require a team of several engineers embedded for months can now be handled by a single FDE working faster with AI coding tools, cutting the total on-site window even when travel itself is still required.

That doesn't eliminate travel; the security, trust, and environment-fidelity reasons covered above haven't gone away. But it does mean the shape of travel is changing: shorter, more concentrated on-site stretches during discovery and go-live, with more of the ongoing monitoring and iteration work happening remotely once a system stabilizes. 

Companies like PostHog, running a deliberately remote-first FDE model, represent an early version of where parts of this role may continue heading though for security-sensitive and airgapped deployments, physical presence is likely to remain non-negotiable regardless of how good the tooling gets.

What a Typical On-Site Stretch Actually Looks Like

Travel for an FDE rarely means a single day trip. On-site engagements typically run in concentrated stretches, and what happens during them varies by phase:

• Discovery visits are usually the shortest, focused on mapping the customer's real systems, meeting stakeholders, and identifying the actual technical constraint before any code gets written.
• Build and integration often stretches the longest on-site periods, sometimes running days to weeks, since this is when an FDE needs continuous access to the customer's environment and fast answers from the people who know it best.
• Go-live and stabilization visits are shorter but higher-intensity, timed around the actual launch to handle issues in real time rather than reconstructing them after the fact from a distance.
• Periodic check-ins once a system is stable, on-site time typically drops to occasional visits rather than continuous presence, unless the customer's environment specifically requires ongoing physical access.

That rhythm front-loaded, intense, then tapering is a large part of why FDE travel doesn't map cleanly onto a fixed weekly percentage. It's better understood as concentrated bursts tied to where an engagement actually is in its lifecycle.

Is Heavy Travel Right for You?

Before pursuing an FDE role specifically for the travel intensity it involves, it's worth being honest about fit. The role tends to suit people who:

• Enjoy building software and talking directly to the people who'll use it, without wanting to give up either
• Can create momentum in ambiguous situations without a fully defined spec
• Want their work visibly and directly connected to business outcomes, not abstracted several layers away
• Are genuinely comfortable with unpredictable travel and schedules, not just tolerant of it in theory

It tends to suit people less well if they prefer deep, uninterrupted focus on a single codebase, need a highly structured and predictable weekly routine, or find frequent travel personally draining rather than energizing.

TL;DR

• Why travel happens: the role requires building inside a customer's real environment, which often means physical presence for security, access, and trust reasons
• Where the term comes from: military language "forward deployed" forces operate near the point of action, not from headquarters
• How much: typically 25–50% of the role, varying heavily by company and industry (defense and healthcare skew higher; some AI labs run hybrid with occasional visits)
• Top reasons: security/airgapped systems, understanding the real (not idealized) environment, building stakeholder trust, on-site debugging, faster iteration
• Not universal: some companies (like PostHog) run fully remote, async FDE models travel intensity depends heavily on the specific company and customer
