Software engineers don’t always work on the same kinds of problems. Some spend years developing a single product, while others work directly with clients, adapting software to their systems, processes, and business requirements.

The second type of work is often associated with forward deployed engineers (FDEs). The role has been getting more attention, particularly among enterprise software and AI companies, as well as businesses looking to implement these technologies.

So, what does an FDE do, how much does the job overlap with traditional software engineering, and why would a company need one?

Who is a forward deployed engineer?

A forward deployed engineer is a software engineer who works closely with a client’s team to solve specific business problems through technology.

Unlike engineers who spend most of their time developing a company’s core product (or build custom software for clients, as we do at Innowise), FDEs are typically more involved in the client’s day-to-day operations. They learn how the business works, identify technical constraints, and figure out which technologies can solve the problem most effectively.

Say a company wants to automate invoice processing. An FDE would first look at how the whole process works and decide which technologies make sense for each step. For example, AI could extract information from invoices, RPA could handle repetitive tasks, and API integrations could transfer data to the accounting system. Some steps might not need AI at all.

Instead of building the entire solution straight away, the FDE could use AI-assisted coding to put together a quick prototype and test it on a small batch of invoices. If it works, they can refine the solution, add the necessary integrations, and prepare it for wider use.

This requires solid software engineering skills, experience with system integrations, and the ability to make technical decisions independently. FDEs also need to understand business requirements and communicate with people who don’t necessarily have a technical background.

And their job doesn’t end once the code works. They also check whether the solution performs reliably and saves the company time.

Forward deployed engineer vs. software engineer: what's the difference?

Both roles require strong programming skills, and there’s quite a bit of overlap between them. In fact, an FDE is a type of software engineer.

The main differences are usually the scope of responsibility, involvement in business decisions, and how the engineer approaches the work.

Here’s a more detailed comparison.

	Software engineer (SWE)	Forward deployed engineer (FDE)
Obiettivo principale	Build, maintain, and improve software products	Solve specific clients’ problems using most suitable software
Obiettivo primario	Product functionality, architecture, performance, and maintainability	Business requirements, prototypes, implementation, integration, testing and measurable outcomes
Approach to tasks	Often works with requirements defined by product owners, analysts, or architects	Helps define requirements, evaluates possible solutions, and proposes how to implement them
L'indipendenza	Depends on seniority and team structure; may work within an established architecture	Usually expected to make implementation decisions and take ownership of a specific solution
Typical responsibilities	Develop features, write tests, fix bugs, review code, improve infrastructure	Analyze business processes, design solutions, build custom functionality, integrate systems, deploy, and optimize
Use of AI	May use AI assistants for coding, testing, debugging, and documentation	In AI-native FDE teams, AI-assisted coding and workflow automation are actively used to accelerate delivery
Who they work with	Engineering, QA, design, product teams, and sometimes clients	Client stakeholders, business users, engineers, and product teams
Ambito del progetto	Often product- or feature-focused	Usually centered on solving a business challenge, automating processes, or improving operational efficiency
Metriche di successo	Software quality, reliability, performance, maintainability, and delivery	Business KPIs, implementation speed, adoption, quality, and operating costs

One difference worth discussing separately is AI-assisted development.

Today, software engineers can use Cursor, GitHub Copilot, Claude Code, and other AI tools regardless of their role. Being an FDE doesn’t automatically mean using AI more often than a traditional developer.

However, in an AI-enabled FDE model, there’s a strong emphasis on finding opportunities to automate development work. Engineers may use AI to generate routine code, create tests, prepare documentation, or prototype features faster. They still need to review the results and handle complex engineering decisions themselves.

Does this mean FDEs are more advanced than software engineers? Not necessarily. These are different specializations, and both can involve complex engineering work.

It’s also worth mentioning that the responsibilities aren’t always strictly separated. Software engineers can work directly with clients, while FDEs can contribute improvements to the core product. The exact boundaries depend on how a company organizes its engineering teams.

How do forward deployed engineers work?

FDEs usually join an existing client team and get involved in everything from understanding the business problem to implementing and improving the solution.

But what makes their approach different from a regular development process?

They figure out what needs fixing. FDEs talk directly to stakeholders and end users, study existing workflows, and look for issues that might not be mentioned in the original requirements. They can also challenge the proposed solution if they see a simpler or more effective alternative.
They choose the technologies that fit the problem. Before development starts, they assess existing systems, data, APIs, and technical limitations. Sometimes custom development is necessary. In other cases, integrating an existing service, introducing automation, or combining several technologies makes more sense.
They automate their own work where possible. In AI-enabled FDE teams, engineers actively use AI coding assistants and development automation to reduce time spent on routine tasks. That might include generating boilerplate code, preparing tests, or creating early prototypes. The goal is to spend less time on repetitive work and more on engineering tasks that require human expertise.
They work directly with the people who will use the solution. Instead of passing every question through several teams, FDEs can clarify requirements, discuss technical limitations, and collect feedback directly. This also makes it easier to adjust the solution during development.
They stay involved after the initial implementation. FDEs test the solution with real data, monitor performance, and make improvements based on actual usage. Depending on the project, they may track accuracy, latency, error rates, operating costs, or other business-specific metrics.

At Innowise, our AI-focused FDE approach starts with one defined use case, access to the required data, and an internal project owner. For suitable projects, we aim to start implementation within 1–2 weeks and demonstrate measurable results by weeks 4–6. The actual timeline depends on the project’s complexity and existing infrastructure.

Common AI use cases for forward deployed engineers

FDEs can work on all kinds of software projects, but AI implementation is one area where their skills come in particularly handy. Here are a few examples of AI solutions they can help businesses implement.

Business area	Example AI solution	Potential benefit	Business outcome
Assistenza clienti	AI copilot or chatbot	Faster responses, higher customer satisfaction	Lower support costs, improved customer retention
Gestione della conoscenza	Smart search with source citations	Less time spent searching, more accurate answers	Higher employee productivity, lower information retrieval costs
Operazioni	AI agents and workflow automation	Less manual work, faster processes	Lower operational costs, increased processing capacity
Vendite e marketing	Lead assistant or personalization	Higher conversion, shorter lead processing time	Potential revenue growth, improved sales efficiency
Analytics & insights	Forecasting, summaries, recommendations	Faster decisions, lower analysis costs	Reduced reporting expenses, better resource allocation
Compliance & governance	AI monitoring and policy enforcement	Lower compliance risks, greater transparency	Reduced compliance workload, lower exposure to costly violations

Check if your business also needs forward deployed engineers

A company doesn't necessarily need an FDE for every software development project.

If you're building a conventional application with well-defined requirements and an established development team, traditional software engineers may already cover everything.

But there are situations where having an FDE on your team can make a real difference. Check if any of these sound familiar.

You want to get your solution up and running faster. Your project involves too many handoffs, lengthy discussions, or repetitive development tasks. FDEs can work directly with stakeholders and use AI-assisted development and automation where appropriate to speed things up.
You know what business problem you need to solve, but aren't sure how. You need someone who can analyze the existing process, compare possible technologies, and suggest a practical approach rather than simply implement predefined requirements.
You want to automate more of your business processes. Your employees spend hours on manual data entry, document handling, or transferring information between systems. An FDE can assess which steps are suitable for AI, RPA, API integrations, or conventional automation.
You're worried about integrating new software with your existing systems. Legacy infrastructure, incompatible APIs, messy data? FDEs investigate these issues early and plan the implementation around the systems you already use.
You want someone to take responsibility for the result. You need an engineer who can make technical decisions, coordinate implementation, and stay involved in testing and performance evaluation.
You need to know whether your investment is paying off. FDEs can help define and track relevant metrics, such as processing time, error rates, operating costs, or user adoption.

If you've checked several boxes, involving an FDE might be worth considering. Especially if your project requires plenty of customization, complex integrations, or close cooperation between technical and business teams.

Riflessioni finali

Forward deployed engineers and traditional software engineers have a lot in common. Both write code, solve technical problems, and build software that needs to work reliably.

The difference lies mainly in their responsibilities and approach to solving problems. FDEs tend to have greater involvement in business and defining the solution, choosing technologies, and working directly with the client throughout implementation.

AI-assisted development can make this approach more efficient, particularly when engineers know which tasks are worth automating and which require careful manual work.

For businesses, the value of an FDE comes down to having an engineer who can understand the problem, make the necessary technical decisions, and follow the solution through to measurable results.
