The largest untapped pool of senior engineers isn't on the job market — they're already employed, and Fraction just built the infrastructure to reach them.
The US software developer shortage has a paradox at its center: there are plenty of senior engineers. They just aren’t available. They’re employed — well-compensated, at established companies — and startups have no realistic path to recruit them away. Fraction’s platform is built around a different premise: don’t recruit them away. Tap what they have left over.
The US software developer shortage is often framed as a supply problem — not enough engineers trained, not enough graduating. But for startups, the real problem is competitive access. Large corporations can offer total compensation packages — salary, equity, benefits, job stability — that early-stage companies simply cannot match. The result is that the candidates who appear on the open job market skew toward less experienced or transitional engineers. The most skilled developers aren’t there.
Software developer shortage: a persistent gap between demand for software engineering talent and the supply of engineers willing to accept available positions at prevailing market compensation. The shortage is structural — it reflects mismatched incentives and access barriers rather than an absolute lack of qualified people in the workforce.
The largest pool of experienced developers is those who are already working. They are producing code at companies that hired them years ago, have deep stack expertise, and are not actively looking. The fractional model is the only distribution mechanism designed to reach this pool — not by luring engineers away from their jobs, but by creating a legitimate channel for their spare capacity.
A fractional developer is a senior engineer who works a defined number of hours per week for a client company without leaving their primary employer. The model has existed informally for decades — Praveen Ghanta, Fraction’s founder, describes using it successfully for 15 years before building Fraction to formalize and scale it.
“This model is perfect for startups who may struggle to compete for developers,” said Ghanta at launch. “I’ve used fractional developers successfully for 15 years — it’s time to scale this solution across the industry.”
The mechanics are straightforward: Fraction recruits and screens senior engineers, manages the engagement structure, and matches them to companies based on technical fit. The company gets senior-level output at a scope they define. The developer earns additional income on a schedule that works around their primary role. No full-time commitment required on either side.
For startups navigating whether to grow headcount or stay lean, the broader question of how software employment is shifting toward specialist roles is directly relevant — fractional hiring is one of the structural responses to that shift.
Matching a developer to a company on the basis of general programming ability produces mediocre results. A React specialist working in fintech is a fundamentally different hire from a Python engineer with machine learning experience in logistics. StackMatch is Fraction’s answer to this problem.
| Dimension | Traditional recruiting | StackMatch |
|---|---|---|
| Screening depth | General coding tests, resume review | Stack-specific technical assessment in candidate’s preferred tools |
| Industry fit | Not systematically assessed | Matched by business vertical alongside technical stack |
| Time to match | Weeks to months | Days via pre-screened pool |
| Access to working engineers | Limited to active job seekers | Includes senior engineers currently employed |
Fraction subjects every developer to rigorous screening tests within their preferred software stack. Companies can then use StackMatch to search candidates with a deep understanding of a specific tech stack and business vertical — not just general competence. The result is a smaller, higher-signal candidate pool rather than a large pool of questionable matches.
Lumiant is an advice engagement platform for financial professionals. After successfully launching in the US, the company needed to scale engineering capacity quickly — adding raw headcount through traditional recruiting would have taken months and introduced significant hiring risk.
Fraction provided fractional developers who were matched to Lumiant’s tech stack. The outcome, in the words of Blake Wood, CEO of Lumiant US: “Fraction enabled us to access technically gifted candidates who could quickly get up to speed and get code into production. By augmenting our already incredible engineering and development team with proven talent, we can continue to scale rapidly and be ahead of the curve in delivering an engaging advice experience.”
The specific metric matters: Lumiant was serving more than 6,000 clients around the world at the time of the announcement. The engineering scale-up wasn’t exploratory — it was production-grade, immediate, and measurable.

Fractional engineering is not the right answer to every hiring need. A company that needs an engineering manager running daily standups and managing a team of five needs a full-time leader. But for a large class of engineering needs — shipping a specific feature, augmenting a team through a sprint, accessing a technical specialty the in-house team doesn’t have — fractional is structurally superior.
The case for fractional is strongest when the scope is defined and the skill requirement is specific. When those two conditions are true, a fractional developer can get up to speed faster and deliver more focused output than a full-time hire who spends their first two months ramping.
It’s also worth understanding the broader dynamics at play. Research into whether software engineer demand is actually peaking shows that the market is not monolithic — demand for specialist skills continues to grow even as generalist hiring softens. Fractional models are better positioned to serve that specialist demand than traditional full-time recruitment.
For companies that want to understand exactly who Fraction’s fractional engineers are and what they bring to client engagements, the Fraction workforce overview provides a direct look at the talent pool behind the platform.
The US has consistently produced fewer software engineers than the market demands, pushing salaries to levels that leave startups at a structural disadvantage. Large corporations can offer equity packages, brand recognition, and job stability that early-stage companies cannot match. Startups end up competing for a shrinking pool of available candidates rather than the full pool of qualified engineers.
Rather than trying to recruit engineers away from existing jobs — which is expensive and often impossible — the fractional model taps their spare capacity. Senior developers at established companies work a defined number of hours per week for client companies without leaving their primary role. This unlocks a pool of experienced talent that never appears on the job market.
StackMatch is Fraction’s candidate screening system. Developers are tested within their preferred software stack and business vertical before being made available to companies. When a company searches for a developer, StackMatch surfaces candidates who have demonstrated proficiency in the specific technologies and industry context the company uses — not just general programming ability.
Fractional developers are best suited for companies that need senior-level output without the overhead of a full-time hire — for example, a startup scaling a specific feature, augmenting an existing team for a sprint, or accessing a specialized skill set for a defined scope of work. Companies that need someone managing a full engineering organization day-to-day typically require a full-time or fractional CTO rather than fractional individual contributors.
Speed-to-productivity depends heavily on how well the developer’s stack matches the company’s codebase. The Lumiant case study cited in Fraction’s launch demonstrates that StackMatch-selected developers were able to get up to speed quickly and get code into production — the explicit requirement Lumiant had when scaling technical capacity after their US launch.
Startups and growth-stage companies that struggle to compete for developers in the open market benefit most. Specifically, companies that have a working product and need to scale engineering output without building a large internal team, or those that need a specialized skill set for a defined period, are the strongest fit for the fractional model.
