Hiring Your First Junior Developer

Most agencies delay this hire too long. The usual pattern: the founder or a senior dev is doing every build personally, contractors get pulled in for overflow at premium day rates, and eventually someone notices that a full-time junior would cost less per month than two months of contractor invoices — while also building institutional knowledge the agency doesn’t lose the moment a contract ends. The right time to hire is when overflow work is repeatable and predictable, not a one-off spike.

Junior hire vs. another contractor

A contractor makes sense for a defined project with a clear end date — a one-off Shopify migration, a single custom plugin. A junior full-time hire makes sense when the work is ongoing and similar in kind: routine WordPress builds, theme customization, ticket-based maintenance work. The math usually tips toward hiring once you’re spending more than roughly 60-80 contractor hours a month on similar work — at typical contractor rates of $25-50/hour for junior-level tasks, that’s $1,500-4,000/month, which is in the same range as a junior developer’s salary but without the contractor’s divided attention across other clients.

Where to actually find candidates

We Work Remotely and Wellfound (formerly AngelList Talent) are the two most agency-relevant boards for remote junior dev hires — posting a listing runs a few hundred dollars on We Work Remotely for a set duration, and Wellfound is free to post but requires more of your own screening since volume is higher and less pre-filtered. Bootcamp alumni networks (General Assembly, App Academy, Flatiron School career services) are worth contacting directly — bootcamp grads are specifically job-hunting and often cheaper to hire than a CS-degree junior, though the skill floor varies more, so your technical screen matters more with this pool. If you’d rather trial someone before committing, Upwork‘s contract-to-hire path lets you run someone through 2-3 real tickets at an hourly rate before offering full-time — this is the lowest-risk way to evaluate someone you haven’t worked with, and Upwork takes a service fee only on the contract portion, not on a subsequent direct hire.

What to actually pay

US-based remote junior developer salaries typically range $45,000-70,000/year depending on region and stack, with WordPress/PHP-focused roles often at the lower end of that band compared to junior roles requiring a modern JS framework. Contract-to-hire trial rates commonly run $20-35/hour during the evaluation period. These numbers move with the market and vary significantly by country if you’re hiring internationally (Eastern Europe, Latin America, and South/Southeast Asia junior rates run well below US figures) — treat these as a starting range to sanity-check an offer against, not a fixed number to quote a candidate.

Set up onboarding before day one

The most common first-hire mistake is dumping live client work on a junior with no structure. Before they start: have a working GitHub (or GitLab) repo with a real README, a ticket system they’ll actually use (Linear or ClickUp, not a Slack DM queue), and at least one recorded walkthrough of your deployment process via Loom so they’re not waiting on a senior dev’s live attention for basic “how do I push to staging” questions. Pair them with a senior dev for code review on every pull request for at least the first month — not as a formality, but because junior mistakes on live client sites (a bad database query, an unoptimized image upload) are expensive to catch after deployment instead of before.

Honest downsides

A junior hire is a productivity drag for the first 1-3 months, not a net gain — budget for that instead of expecting immediate output parity with a mid-level contractor. Code review overhead is real time from your senior developer(s), which is a cost most agencies forget to account for when comparing “contractor hourly rate” to “junior salary.” And if your pipeline of similar work dries up (a big client leaves, a niche you were building for shrinks), a full-time junior is a fixed cost a contractor never was — this is the actual risk being traded for lower long-term cost and better retention of institutional knowledge.

Verdict

Hire when overflow work is repeatable, not when you’re simply busy for a month. Screen through a real trial (Upwork contract-to-hire, or a paid test ticket) rather than a resume and interview alone — junior developer resumes are notoriously unreliable predictors of on-the-job output. Budget the first quarter as a net cost, and put code review structure in place before their first day, not after the first mistake ships.

FAQ

Should I hire a bootcamp grad or a CS degree holder for a WordPress-focused agency?
Bootcamp grads are frequently a better fit for agency WordPress/PHP work specifically, since bootcamp curricula lean practical web development; a CS degree matters more for roles needing deeper algorithms/systems knowledge, which most agency client work doesn’t require.

How long should the trial period be before a full-time offer?
Most agencies run 2-4 weeks of contract-to-hire work covering 2-3 real (but low-risk) tickets before converting — long enough to see actual output and communication style, short enough not to string a candidate along.

What’s a reasonable ratio of senior dev time to junior oversight?
Expect roughly 3-5 hours/week of a senior developer’s time on code review and questions during the first month, tapering as the junior handles more independently by month three.

Is it cheaper to hire internationally instead of US-remote?
Often yes on salary, but factor in timezone overlap with your team and clients, and payroll/contractor-compliance complexity (a service like Deel or Remote handles this) — the salary savings can be partly offset by that overhead.
