FPGA and RF engineering services or a new hire: How to decide

The short answer: Use FPGA engineering services when the FPGA or RF work will not recur, the schedule cannot absorb a months-long search plus ramp, or the work fails at discipline seams one hire cannot cover. Hire when the work recurs, the runway is twelve months or more, and the architecture is what your customers buy.

The engineers are not available to hire, so the decision in front of an engineering leader is which work to move while the req stays open. Aerospace and defense companies put engineering first for hiring difficulty, at 76 percent of the 25 member organizations AIA and McKinsey surveyed in 2025, ahead of skilled manufacturing and software engineering. Engineering also topped their list of highest-demand functions, at the same 76 percent, so demand and difficulty land on the same people.

Which work moves matters more than how many people get added. RF and high-speed designs rarely fail inside a discipline. They fail at the seams: between the RF chain and the digital back end, between the FPGA and the board it sits on, between the board and the thermal path carrying its heat away. One engineer, however good, lands on one side of one seam and takes the others on faith.

A requisition and a program schedule run on different clocks, and that mismatch turns a hiring problem into a delivery problem. An open req costs nothing visible. It sits in the applicant tracking system, gets reviewed each week, and nobody has to explain it. The schedule it was opened to protect burns down the whole time, so waiting becomes the decision nobody made.

Key takeaways

• Engineering is the hardest A&D role to fill: 76% of organizations in the 2025 AIA–McKinsey workforce study ranked it first for hiring difficulty and first for demand.
• The pool is draining: talent leaves aerospace and defense for the tech sector at twice the rate it comes back (AIA–McKinsey), and mid-career engineers are the hardest to recruit.
• Three questions settle the decision: does the FPGA or RF work recur, does the schedule allow a search plus a ramp, and does the work differentiate the product.
• Move Context, keep Core: Capgemini’s framework sends validation, documentation, non-critical mechanical design and mature-product maintenance to a partner, while architecture stays in-house.
• Seams need a multi-discipline team: FPGA engineering services that cover FPGA, PCB, SI/PI, embedded software and thermal validate the interfaces a single hire cannot. Fidus reports 99% first-pass success across 4,000+ projects.

Why aerospace and defense engineering hiring stays hard

The shortage is a market condition and not a comment on any particular team. AIA and McKinsey found talent leaving aerospace and defense for the technology sector at twice the rate it flows back, and executives in that study named mid-career engineers as the hardest people to recruit. That is the seniority a program needs. RF sits at the sharp end of it. A specialist recruiter’s read of the 2026 market lists microwave engineering, antenna design and radar among the hardest skill sets to source. It also notes that most experienced RF engineers are already employed and rarely looking, and a candidate who is not looking will never see the job posting.

The two studies with the best data on this diverge on almost everything except their prescription, and neither prescribes hiring. Capgemini found 73 percent of aerospace and defense executives treat the talent shortage as a threat to engineering and R&D over the next three to five years. Its recommendation is a Core and Context assessment: separate the work that creates competitive differentiation from the work that does not, hold the differentiating work close, and route the rest to a trusted engineering partner. AIA and McKinsey arrive in the same place from a different direction, and put the answer in getting more out of the people already on the payroll.

Three questions before hiring an FPGA or RF engineer

The three gaps that send teams looking for outside help look identical on a hiring plan and have different right answers. Working out which one you have takes ten minutes and saves a quarter.

Will the FPGA or RF work recur after this program?

A team builds one RF front end, ships it, and does not touch RF again for three years. A capability used once every three years does not get better. Tool versions move, device families change, and the engineer who closed timing last time has spent two years elsewhere. Capability used only occasionally is expensive to keep and slow to restart.

A skills gap in a discipline the organization will never own is not a hiring problem. Hiring for it produces an expensive specialist with nothing to do in year two and an obsolete toolchain in year three. If the capability will be exercised again, and regularly, the calculation changes and the next two questions barely matter.

Does the schedule allow a search plus a ramp?

This question is arithmetic, and it settles most cases on its own. Filling a specialized engineering role takes months before anyone writes a line of HDL. The new hire then needs time to learn the architecture, the toolchain, the verification environment, and the reasons behind decisions made before they arrived. Set that against a delivery date that does not move and the window either exists or it does not.

Teams get this wrong by comparing the wrong things. The comparison that matters is the date the work starts under each option. Cost of a contract against cost of a salary is the comparison most teams reach for, and it answers a different question. A capacity gap on work the team already knows how to do, with twelve months of runway, is the case where hiring genuinely wins. Move the market window in to six months and no recruiter closes that arithmetic.

Does this work differentiate the product?

Being strict about what Context means is what makes Capgemini’s split usable. The framework names validation, documentation, non-critical mechanical design, and the maintenance of mature product lines as work that can move. It is explicitly about work that does not differentiate.

Capgemini’s own answer to the shortage is a global one, with system architecture held close to the program and other work distributed to wherever the engineers are. For the categories it names, that logic is sound. What the framework does not license is moving Core work because Core work is hard to hire for. The RF front end that sets a receiver’s sensitivity, or the FPGA carrying a product’s signal processing, is differentiating by any reading of that test. It stays differentiating after the req has been open five months. Work that defines the product goes to a team you can hold accountable for it and get into a design review the same week.

When hiring an FPGA or RF engineer is the right call

The strongest argument against using an outside design firm is about where the knowledge ends up, and anyone who has run a program knows it. When a contract closes, the engineers who made the architectural decisions leave with the reasons for them. Documentation almost never captures those reasons well enough, and a company that never builds internal depth loses the ability to evaluate its partner’s choices two product generations later.

For a team building a family of products on one compute architecture over five years, that objection is correct and headcount is the cheaper structure. The work recurs, the knowledge has somewhere to accumulate, and the ramp gets paid for once. The same holds when the architecture is the product, which is common in defense electronics. A company whose advantage is how it maps a processing chain onto silicon is contracting out the thing its customers buy.

There is a third case that responds to neither hiring nor a partner. If the constraint is that senior engineers spend their weeks in the lab instead of in design, adding people to that system adds coordination. AIA and McKinsey were describing that situation when they put productivity ahead of recruitment, and it is worth ruling out before either budget goes up for approval.

What FPGA engineering services buy that a single hire cannot

A team carrying every relevant discipline validates the seams themselves, which is the part a single hire cannot reach. Fidus keeps FPGA design, hardware and PCB layout, signal and power integrity, embedded software, and mechanical and thermal design under one roof. The bench runs to 150-plus engineers across three North American design centers, and more than 80 percent of projects carry FPGA content. Fidus reports a 99 percent first-pass success rate across more than 4,000 projects. Behind that claim sits First Time Right, a process discipline rather than a slogan. It runs on simulation before hardware, design review at every stage, and engineers who have already seen the failure modes that close an eye diagram or open a timing path. Most of these engagements start with a single defined subsystem, and the rest of the structure follows from what that first one proves.

Getting an RF or FPGA design right the first time

Engineering is the hardest function in aerospace and defense to hire into, the pool is draining toward better-paying sectors, and the published answers to that condition all involve redistributing work. Sort the work first: what recurs, what the calendar allows, and what genuinely differentiates the product. Bring in a partner for the parts that fail at the seams, and keep the architecture and the acceptance criteria with the leader who answers for the program.
