Why Mid-Career Feds Are Making the Move
The pattern shows up every few years at Redstone and MSFC: a GS-13 or GS-14 engineer hits the pay ceiling, watches a former colleague land at a prime for $30,000–$50,000 more per year, and starts asking questions. The questions are good ones, and they deserve straight answers — not a recruiter's pitch.
This is not an argument for leaving federal service. It's a map of the actual mechanics for someone who's already thinking about it.
The Pay Translation
GS-13 Step 10 in the Huntsville locality pay area runs roughly $130,000–$140,000 in 2024 base plus locality. GS-14 Step 10 is roughly $153,000–$165,000 in the same band. Those numbers are public; look them up on OPM.gov.
Contractor salaries for equivalent roles at the Huntsville primes — Lockheed Martin, Northrop Grumman, Leidos, Jacobs, SAIC, Boeing — typically land in these rough bands for mid-career engineers with active clearances:
- Systems engineer, 10–15 years, TS/SCI: $145,000–$185,000
- Program/project engineer, 14+ years, TS/SCI: $160,000–$210,000
- Chief/lead engineer roles with named-program experience: $190,000–$240,000+
The spread is wide because it depends on your clearance level, whether you have specific program pedigree (SLS, missile defense, IBCS), and whether the contractor is bidding your salary into a proposal.
Two things offset the gross number bump: federal benefits are genuinely better (more on the pension below), and contractor bonuses are not guaranteed. A $175,000 base with a 10% target bonus is not the same as $192,500 — the bonus is tied to DCAA-approved overhead structures and contract award fees that can get cut.
The Cooling-Off Period: Read This Before You Take a Call
The post-government employment rules under 18 U.S.C. § 207 are the piece most engineers underestimate.
If you were a "procurement official" — meaning you had authority over contracts, served as a Contracting Officer's Representative, or personally and substantially participated in a specific acquisition — you face a two-year cooling-off period on that specific matter. You cannot represent a contractor back to the government on that same procurement.
For a GS-13/14 engineer who was a COR, program analyst, or involved in source selection, this is real. It doesn't mean you can't work for a contractor at all. It means you need to be explicit with your ethics counselor and with your future employer's compliance team about what you touched and when.
The one-year senior official restriction (if you were in an SES-equivalent role or certain acquisition positions) is a separate layer. The point: get a written determination from your agency ethics official before you start negotiating offers. This process takes four to eight weeks, not a day — factor that into your timeline.
The Pension Question
FERS employees hired after 1987 vest in a pension after five years. The pension formula (1% × high-3 salary × years of service, or 1.1% if you retire after 62 with 20+ years) pays less than most people assume at mid-career departure. A GS-13 leaving at 20 years of service, high-3 of $140,000, collects roughly $28,000/year starting at MRA — not nothing, but not a golden handcuff if you're 40 years old.
TSP: Leave It or Roll It
Your TSP balance is yours either way. The decision:
- Leave it in TSP: Institutional funds with extremely low expense ratios (the G Fund, C Fund, etc. are hard to beat on cost). You keep access at retirement age. This is often the right call just on fees.
- Roll to a traditional IRA or new employer 401(k): Makes sense if you want consolidation or your new employer's plan has a strong match structure. Most contractor 401(k) plans are decent but not TSP-cheap.
Do not cash it out. That's a 10% penalty plus ordinary income tax on the full amount if you're under 59½.
FEHB is the other piece. You lose federal health insurance when you separate unless you retire. Contractor plans vary widely — get the benefits package in writing before you sign anything and run a real cost comparison. Family coverage at a mid-size contractor can run $400–$700/month employee contribution; some large primes are better.
The Culture Shift: Billability Is Not a Budget Line Item
Federal engineers work within appropriations. Money is allocated by fiscal year, programs slip, and nobody's personal employment is directly tied to whether a specific contract gets awarded this quarter.
Contractor work is different. The word you'll hear constantly is billability — the percentage of your hours that can be charged to a funded contract line. Most contractors expect 85–95% direct charge. The hours you spend on internal proposals, training not tied to a contract, or general company business are overhead — and overhead is what gets cut in a bad year.
This isn't a criticism of the model. It's just different. What it means practically:
- Your manager cares whether you're on a funded program. If your program ends and there's no follow-on, you are on the bench and that has a clock.
- Proposal work is real work but often unbillable. You'll be asked to contribute to captures on your own time or against overhead budgets that are already thin.
- Job security correlates directly with program health. When MSFC announces a new contract, contractors are watching the award announcement the same way you'd watch a job posting.
GS engineers who've spent careers in stable program offices sometimes underestimate how much of their identity was wrapped up in the program, not the employer. That carries over — but the employer now has a financial stake in your utilization.
Making the Decision
The honest summary: the pay increase is real, especially past GS-13 Step 6 where federal raises slow to a crawl. The benefits gap is real too, but smaller than federal lore suggests for engineers under 45. The cooling-off rules are manageable if you get ahead of them. The culture shift is the variable most people don't fully price in.
A few things worth doing before you decide:
- Pull your FERS projections from OPM's online calculator with your actual numbers.
- Request a written ethics opinion from your agency before taking any interviews.
- Ask contractors you're talking to for their billability expectations and what happens when a program winds down.
- Talk to engineers who made the jump two or three years ago — not recruiters.
The move makes sense for a lot of people. It doesn't make sense for everyone. Knowing the difference requires your actual numbers, not anyone else's anecdote.
