1. Define the role before you look
The single biggest predictor of a good hire is a clear brief. Before you post anything, write down three things: what the developer will build in their first 90 days, the stack they'll work in, and what "good" looks like for you (speed, code quality, autonomy, communication). A vague "we need a developer" invites a flood of mismatched applicants and pushes the screening burden onto you.
Decide, too, whether you need front-end (what users see and interact with), back-end (servers, databases, logic), or full-stack. Asking for "full-stack senior" when you only need a front-end build is a common way to overpay and under-fill.
2. Choose where to look
Each channel has a different trade-off between speed, cost, and vetting depth:
- Job boards (LinkedIn, Indeed): widest reach, but you do all the screening and the process runs weeks.
- Freelance marketplaces (Upwork, Toptal, Arc): fast for project work; quality varies unless you pay for a pre-vetted tier.
- Referrals: highest hit-rate, lowest volume — always ask your network first.
- Staffing / employer-of-record partners: they vet and place a dedicated developer and handle employment for you — less DIY screening, faster to a qualified shortlist.
3. Screen for real skill, not résumé keywords
A résumé tells you where someone worked, not whether they can do your job. Screen against the actual work: ask for a portfolio with live links, then run a short, paid, real-world exercise close to what they'd actually build — not an abstract algorithm puzzle. Watch how they communicate as much as how they code; a developer who writes clear updates and asks good questions will save you far more than one who's marginally faster but silent.
Check three things every time: can they build the thing (skills test), can they work with your team (communication, English, timezone overlap), and will they stick (motivation, stability). Skipping the second and third is how technically-fine hires still fail.
4. Structure the engagement to de-risk it
However you hire, build in a way to be wrong cheaply. For freelancers, start with a small paid milestone before a big commitment. For a dedicated hire through a staffing partner, use a trial period on real work before it becomes permanent — at Webly Studio, for example, every placement starts with a three-day free trial so you confirm the fit before you commit.
Then set the person up to succeed: a clear first task, access to what they need on day one, and a named point of contact. The fastest way to lose a good developer is a chaotic first week.
