A forward deployed engineer builds and runs production work for one customer after the sale. A solutions engineer, sales engineer or solutions architect usually works around the sale, with demos, proofs of concept and designs that show a product can fit. Employers use these titles loosely, so the job description matters more than the title.

## Key takeaways

- The main dividing lines are timing (before or after the sale) and whether the person owns production code.
- Solutions engineer is the loosest title: pre-sales at some employers, post-sale configuration at others.
- Sales engineers have a government wage median of $124,900 (May 2025); forward deployed postings advertise a median midpoint of $198,000 in base pay.

## What does each role do?

The four titles split mainly on timing, before or after the sale, and on whether the person writes code that runs in production.

**Tendencies, not rules: employers use these titles differently**

| Role | Main work | When | Writes production code? | Usually measured by |
| --- | --- | --- | --- | --- |
| Forward deployed engineer | Builds, deploys and runs the product on one customer's systems and data | After the sale, for weeks to months | Yes | A deployment people use |
| [Solutions engineer](https://forwardeployed.work/guides/forward-deployed-glossary#solutions-engineer) | Demos, proofs of concept and technical answers; post-sale configuration at some employers | Mostly before the sale | Sometimes | Deals supported |
| [Sales engineer](https://forwardeployed.work/guides/forward-deployed-glossary#sales-engineer) | Explains the product's technical case to buyers and proves it works | Before the sale, some troubleshooting after | Rarely | Revenue, often with commission |
| [Solutions architect](https://forwardeployed.work/guides/forward-deployed-glossary#solutions-architect) | Designs how the product fits the customer's wider systems | Before and during implementation | Rarely | Designs adopted |

The encyclopedia entry on [sales engineering](https://en.wikipedia.org/wiki/Sales_engineering) describes a hybrid of sales and engineering that covers both pre-sales help and post-sale troubleshooting, usually paid as salary plus commission. A [solutions architect](https://en.wikipedia.org/wiki/Solutions_architect) produces designs, options and plans for a specific solution rather than running it.

## Where do the roles overlap?

They overlap most after the sale, where the same job can carry any of the four titles.

The [encyclopedia entry on the role](https://en.wikipedia.org/wiki/Forward_Deployed_Engineer) lists solutions architects and sales engineers among the jobs a forward deployed engineer's duties overlap with. A venture investor's essay on [forward deployed job titles](https://a16z.com/forward-deployed-job-titles/) argues that the original title was given to what had been solutions and integration engineers, a rebrand that raised the status of the work.

The practical line is hands-on code. [The Pragmatic Engineer](https://newsletter.pragmaticengineer.com/p/forward-deployed-engineers) reports that at one AI model developer, solutions architects rarely write code on customers' infrastructure, while its forward deployed engineers are much more hands-on. The [glossary](https://forwardeployed.work/guides/forward-deployed-glossary) defines each title and the terms around them.

## How does pay compare?

Public figures exist for sales engineers; for forward deployed engineers there are mostly posted ranges, so compare with care.

The US Bureau of Labor Statistics puts the median annual wage for [sales engineers](https://www.bls.gov/ooh/sales/sales-engineers.htm) at $124,900 in May 2025. US forward deployed postings in our [Hiring Index](https://forwardeployed.work/guides/forward-deployed-engineer-hiring-index#pay) advertise a median base range of $160,000 to $230,000, with a median midpoint of $198,000. The structures differ too: sales engineers are often paid salary plus commission, while these are base ranges alone, so compare total pay, not base pay.

See [how much a forward deployed engineer makes](https://forwardeployed.work/guides/forward-deployed-engineer-salary) for pay by level and city.

## How can you tell which job a posting really is?

Read for three signals: when the work happens, where the code runs and what you are measured on.

1. **Timing.** Does the role start before a contract is signed, or after? Pre-sales work points to a solutions or sales engineer, whatever the title.
2. **Code.** Will you write and maintain code that runs on the customer's systems, or build demos and designs on sample data?
3. **Measure.** Is success a deal, a design or a deployment that people use every week?

Travel will not settle it, because both kinds of role travel: 53% of forward deployed postings mention it. See [whether forward deployed jobs are remote](https://forwardeployed.work/guides/are-forward-deployed-engineer-jobs-remote), and [forward deployed engineer vs software engineer](https://forwardeployed.work/guides/forward-deployed-engineer-vs-software-engineer) for the comparison on the product side.

## Frequently asked questions

### Is a solutions engineer the same as a sales engineer?

Often. At some employers the two titles describe the same pre-sales job of demos, technical answers and proofs of concept. Others use solutions engineer for post-sale work that configures the product for a customer, which comes closer to forward deployed work. The job description settles it.

### Can a solutions engineer become a forward deployed engineer?

Yes, and the customer skills carry over. The gap is usually production ownership: writing code that runs on a customer's systems, keeping it running and handing it over. Shipped engineering work is the strongest evidence to bring.

### Do forward deployed engineers have sales targets?

Usually not directly. They are typically measured by a deployment that people use, though a successful first deployment often makes the case for a larger contract. Sales engineers, by contrast, are commonly paid partly on commission.
