Field guide

Software Developer design board

When the role fits
Do not add a labor category just because it appears in an internal org chart.
Signal
Builds, modifies, tests, documents, and supports applications, integrations, scripts, or software components.
Response
Use this role when those duties are central enough to price and order.
Deliverables
Weak duties make pricing harder to defend.
Signal
Code, unit tests, APIs, integration scripts, release notes, defect fixes, technical documentation, and deployment support.
Response
Name actual outputs so the description feels like work, not a title collection.
Qualifications
Separate developer levels by technical authority, not just by years of experience.
Signal
Programming experience, framework or language knowledge, SDLC familiarity, testing discipline, and code-review maturity.
Response
Write minimum qualifications that match the work and the proposed level.
Pricing
Do not make every category senior because the rate looks better.
Signal
Rates should move with architecture responsibility, language depth, independence, security context, and delivery complexity.
Response
Use commercial support, payroll/build-up logic, CALC+ research, and role complexity together.
Role design

Software Developer labor category proof stack

A credible labor category is more than a title. It should explain what the person does, why the qualifications fit, and how the rate makes sense.

Duties
5
Code, unit tests, APIs, integration scripts, release notes, defect fixes, technical documentation, and deployment support.
Qualifications
5
Programming experience, framework or language knowledge, SDLC familiarity, testing discipline, and code-review maturity.
Pricing support
4
Rates should move with architecture responsibility, language depth, independence, security context, and delivery complexity.
SIN fit
4
The role should belong under the SINs where it will be quoted.
Buyer usability
4
The role should be easy for a buyer to understand and order.
Relative role-design scorecard, not an official GSA scoring model.
Part 1

What a Software Developer actually does

Builds, modifies, tests, documents, and supports applications, integrations, scripts, or software components.

Code, unit tests, APIs, integration scripts, release notes, defect fixes, technical documentation, and deployment support.

Part 2

How to write the qualifications

Programming experience, framework or language knowledge, SDLC familiarity, testing discipline, and code-review maturity.

The minimums should be specific enough to justify the role, but not so inflated that the category becomes hard to staff or hard for buyers to use.

Part 3

How to think about pricing

Rates should move with architecture responsibility, language depth, independence, security context, and delivery complexity.

CALC+ can help with market research, but the final rate story should still connect to the company's commercial practice and the way the role is delivered.

Part 4

Watch-out

Separate developer levels by technical authority, not just by years of experience.

A clean labor catalog is easier to quote from because every role earns its place.

Examples

What this looks like in practice

In actionSoftware Developer in a real task order

A developer builds an internal dashboard, writes API integrations, fixes defects, and documents release changes.

A strong labor category page should make it easy to see why the role exists, what it produces, and how it would be staffed on a real order.

Add LCAT noteThe modification should show the before-and-after

If Software Developer / Application Developer is being added through eMod, the package should explain the new title, duties, qualifications, SIN support, pricing support, and whether the Services Plus File or service description needs to change.

  • Title
  • Duties
  • Qualifications
  • Rate support
  • SIN mapping
  • Service file impact

Frequently asked questions

Can Software Developer / Application Developer appear under more than one SIN?

Sometimes. The role can support multiple SINs when the duties and scope genuinely fit each lane. The description should not become so broad that it stops meaning anything.

Should this role have levels?

Only when the levels change duties, independence, customer exposure, experience, certifications, or technical depth in a way a buyer and reviewer can understand.

What should I check before adding it in eMod?

Check SIN fit, service description impact, pricing support, qualifications, commercial support, and whether the role appears in the Services Plus File or related documents.
