Job Description Do's and Don'ts
A clear job description attracts the right candidates and filters out mismatches. Focus on responsibilities, impact, and must-have qualifications.
| Do | Don't |
|---|---|
| Specify the scale (teams, engineers, systems, users) and primary responsibilities. | Use vague phrases like "help out with architecture" without clarifying ownership. |
| List measurable outcomes expected in 6–12 months (e.g., reduce incident rate by X, ship major platform migration). | Include every possible skill as 'nice to have' — this creates unrealistic checklists. |
| Call out the people leadership expectations (managing managers, hiring targets). | Overemphasize years of experience as the only qualification. |
| Be explicit about remote/hybrid/onsite expectations and travel. | Hide compensation range or location requirements that affect candidate fit. |
Keep language inclusive and specific about scope, team size, tech stack, and leadership expectations.
Sourcing Strategy
Targeted sourcing identifies engineers with the right blend of technical depth and leadership experience.
- Referrals Leverage internal engineering and product teams for referrals — high signal for culture and performance fit.
- LinkedIn and professional networks Search for titles like Director of Engineering, Senior Engineering Manager, Head of Eng in complementary industries and filter by technologies and team sizes similar to yours.
- Executive recruiters and niche agencies Use retained or specialized contingency recruiters for hard-to-fill senior roles; ensure they understand your culture and outcomes.
- Alumni and industry meetups Engage with candidates from successful companies in your space through conferences, open-source projects, and alumni groups.
- Inbound content and employer brand Publish engineering blog posts, talks, and case studies that showcase technical leadership and problems the team is solving.
Diversify channels to avoid homogenous candidate pools and emphasize referrals for senior roles.
Screening Process
A structured screening process reduces bias and ensures you evaluate leadership, technical judgment, and culture fit consistently.
- Resume and portfolio screen Check for scope (teams led, systems owned), measurable outcomes, and relevant domain experience. Look for progression and impact over time.
- Recruiter screening Confirm motivations, compensation expectations, location/remote requirements, and cultural fit. Validate basic leadership and technical background.
- Hiring manager phone screen Discuss leadership style, examples of shipping large projects, handling incidents, and building organizations. Evaluate strategic thinking.
- Technical leadership deep dive Panel interview with senior engineers/EMs focusing on architecture decisions, technical tradeoffs, design critique, and previous technical roadmaps.
- Behavioral leadership interview Assess coaching, hiring, conflict resolution, and stakeholder influence through behavioral questions and real scenarios.
- Final executive interview Validate alignment with company strategy, ability to partner cross-functionally, and fit for executive communication.
- Reference checks Speak with former peers, direct reports, and supervisors to validate leadership claims, management style, and delivery track record.
Keep each stage time-boxed and communicate timelines clearly to candidates.
