How to Hire a Software Developer: A Process That Works

Step 1: define the work

Write down what the developer will build or maintain in the first six to twelve months, the technologies involved, who they will work with, and what success looks like. Decide the level honestly: someone who can work independently on ambiguous problems is a different hire from someone who will implement well-specified tasks. This definition drives every later step.

Step 2: write an honest posting

Describe the actual work, the team, the stack, the working arrangement, and the salary range. List only genuine requirements; long wish lists deter strong candidates who meet most but not all. Avoid inflated titles and vague phrases that could describe any role. A specific posting filters candidates before you read a single application.

Step 3: source in the right places

Referrals from people who have worked with a candidate remain one of the strongest signals. Developer communities, open-source projects, and niche job boards for your stack reach people general boards miss. For specialised areas such as AI or onchain development, targeted boards and communities are usually more productive than broad platforms. Agencies can help for senior or urgent roles at a cost.

Step 4: assess real skills

Use assessments that resemble the job: a short paid take-home task, a pairing session on a realistic problem, a review of code with deliberate issues, or a deep conversation about something the candidate built. Keep the process short and consistent across candidates, with clear criteria agreed in advance. Avoid long unpaid assignments and puzzles unrelated to the work, which select for free time and puzzle practice rather than ability.

Step 5: verify

Check references with people who worked directly with the candidate, and ask specific questions about their work. For remote hires, verify identity through video calls and documentation, and watch for inconsistencies between interviews and onboarding. Remote hiring fraud, including impersonation and proxy interviews, has made verification a standard step rather than a formality.

Step 6: make the offer and onboard

Move quickly once you decide: good developers often have several processes running. Present a clear written offer with compensation, start date, and key terms. Before the start date, prepare equipment, access, a first small task, and a person responsible for helping the new hire. The first ninety days decide whether a good hire becomes a productive one.

Writing interview criteria

Before interviewing, agree on what good looks like for each stage: the skills being assessed, what a strong, acceptable, and weak answer looks like, and who decides. Written criteria reduce bias, make interviewers consistent, and speed up decisions, because the debrief compares evidence against criteria rather than impressions. Review them after each hire to see which predicted performance.

Compensation

Research current pay for the role, level, and location from reliable salary data, and decide your range before posting. Include it in the posting where possible; many candidates skip roles without one, and some jurisdictions require it. Be ready to explain equity, benefits, and how raises work, especially for startup roles where cash may be lower.

Common mistakes

• Hiring for a title rather than for the work.
• Interview processes with too many rounds and slow feedback.
• Over-weighting algorithm puzzles for product engineering roles.
• Skipping reference and identity checks under time pressure.
• No onboarding plan, so the first weeks are wasted.
