Fractional developers are part-time — but that doesn't mean they're hard to reach. Here's how the model actually works in day-to-day software teams.
One of the most common objections I hear when discussing fractional employment is: “I don’t see how this can work — I need my developers available during office hours.” It is a reasonable concern. It is also, in almost every case, based on a misunderstanding of how software development teams actually operate.
The concern is intuitive. If you hire someone for 20 hours per week, you might picture them disappearing for the other 20 hours — unreachable when a production issue hits, absent when a fast decision is needed, missing from the standups where context accumulates. That mental model makes fractional work sound impractical.
The reality is different. Based on personal experience as a fractional developer, years of employing fractional developers at Fraction, and consistent feedback from our clients, the availability concern rarely materializes in practice. Here is why.
Fractional developer: a senior software engineer who works for a company at a defined fraction of full-time — typically 0.5 FTE (20 hours per week) — while remaining integrated into the team’s communication, ceremonies, and delivery cadence. Distinct from a consultant or contractor in that the relationship is ongoing and embedded rather than project-scoped.
Most software development teams are not structured around constant availability. They are structured around focused blocks of work punctuated by a small number of coordination touchpoints.
The industry norm is roughly one structured meeting per day — a daily standup of 15 minutes or less, plus the occasional sprint ceremony. Software developers, more than almost any other knowledge-work role, need uninterrupted time to write code. Fragmented schedules hurt their output. Fewer meetings, not more, is the standard that high-performing engineering teams aim for.
Fractional developers are all US-based at Fraction, which eliminates the time-zone problem that makes offshore teams genuinely difficult. Within US business hours, a developer working 20–30 hours per week can attend standups, respond to Slack messages, and participate in planning sessions without the scheduling gymnastics offshore arrangements require.
Fraction asks fractional developers to join 2–3 standups per week, scaled to where they fall in the 20–30 hour per week range. They also attend two longer meetings per week — typically a requirements review and a delivery check-in — to ensure they stay current on what is being built and are delivering against it.
This mirrors the cadence most software engineers already operate under. A developer attending five standups and two planning meetings every week is a developer whose calendar is already fragmented. Most engineering managers recognize this and protect coding time accordingly.
In a remote setting, switching between a fractional engagement and another role is operationally simple. The modern office in software development is Slack and video calls. A developer can attend a standup, return to focused work, and be back on Slack within the hour — exactly as they would in any remote environment.
Yes, with one exception. Fraction requires all fractional developers to maintain active Slack or Teams presence throughout the business day. In practice, senior developers are skilled at acknowledging requests even when they cannot engage deeply at that exact moment — a quick acknowledgment and an estimated response time is standard professional behavior at that experience level.
The one case that does not work is a developer who has a full-time job requiring five days per week in a physical office. That kind of schedule makes genuine Slack presence impossible. Fraction screens for this. It is also worth noting that the workforce willing to take on fractional work skews toward motivated, self-directed senior engineers — people who, by temperament and track record, manage their time and commitments well. Startup founders routinely work 60 hours per week. Medical residents work 80–100 for years. The supply of senior developers willing to work 40 hours at one job and 20 at another is larger than skeptics assume.

Fractional developers are 100% remote. If your company requires daily in-office attendance or involves physical infrastructure that cannot be managed remotely, the model is not a fit. That is a genuine constraint, and it is worth naming clearly.
For the majority of software teams — which are hybrid or fully remote, and trending further in that direction as companies shed real estate and standardize on async communication — the constraint rarely applies. Surveys consistently show that software developers are among the most remote-friendly roles in the workforce, and that trend is not reversing.
Fractional developers are not invisible in hybrid setups. At HiddenLevers, fractional developers attended offsites and occasional in-person team events. In a remote-first world, the occasional in-person touchpoint is accessible to fractional team members in the same way it is accessible to full-time remote employees.
The output argument is the strongest case for fractional hiring, and it is the part of the model most often underestimated. A senior developer working 20 hours per week routinely accomplishes 80–100% of a mid-level developer’s full-week output.
The leverage comes from experience. Senior developers solve problems faster, hit fewer dead ends, write cleaner code that requires less rework, and need less day-to-day oversight. They can read a requirements document and start shipping without extensive hand-holding. They can identify architectural problems before they become expensive. They can unblock junior teammates in a single conversation that would otherwise take days to resolve through back-and-forth.
The cost-per-output comparison often comes out clearly in Fraction’s favor when stacked against a full-time mid-level hire with recruiting costs, ramp time, benefits overhead, and equity dilution factored in. Finding the right full-time developer is itself a costly and time-consuming process. Fractional engagements start faster, carry lower fixed cost, and scale up or down with the work.
The summary: if your company does not require mandatory daily in-office attendance, and your team operates on modern communication tools, working with fractional developers should feel — operationally — completely normal.
Yes. Fractional developers at Fraction are all US-based, which eliminates the time-zone mismatch common with offshore teams. Working at 0.5 FTE or higher, they maintain consistent Slack presence throughout the business day and attend 2–3 standups per week plus key sprint ceremonies. In practice, many clients find fractional developers more responsive than some full-time employees.
The minimum is 0.5 FTE, or roughly 20 hours per week. Below that threshold it becomes difficult to maintain meaningful continuity on a codebase and stay current with a team’s evolving requirements. Half-time ensures the developer is genuinely embedded in the workflow rather than acting as a periodic consultant.
Fraction asks fractional developers to join 2–3 standups per week and 2 longer planning or review meetings per week. This covers the core coordination touchpoints without overloading schedules. Most software developers — fractional or full-time — attend roughly one structured meeting per day, and Fraction’s model is designed to mirror that rhythm.
Fractional developers are 100% remote, so companies requiring mandatory daily in-office attendance are not a fit. However, fractional developers can and do participate in offsites, company events, and occasional in-person gatherings. For the majority of software teams — which are hybrid or fully remote — the model works without any meaningful operational difference.
For most product engineering work, yes. A senior developer working 20 hours per week typically produces 80–100% of a mid-level developer’s full-week output because of faster problem-solving, fewer dead ends, and less need for oversight. The leverage comes from experience, not raw hours. Cost-per-output often comes out significantly lower with a fractional senior than a full-time mid-level hire.
Fractional hiring does not work well when a role requires full-time, in-office presence or involves physical infrastructure that cannot be managed remotely. It also works better with senior developers who can manage their own schedules independently — fractional is not the right format for someone who needs heavy day-to-day management or is still building foundational skills.
