Cold-Sourcing-Technique

4 min readStatus:Seedling

Cold sourcing is the practice of proactively identifying and contacting candidates who are not actively seeking a new role. Most engineering managers avoid it because it feels awkward or inefficient — Larson argues this is a mistake, and provides a concrete, time-boxed recipe to make it systematic and sustainable.

The Five-Step Recipe

  1. Search — Use LinkedIn Recruiter or LinkedIn search with specific filters matching the role: skills, experience level, company background. Avoid generic searches; precision reduces noise.
  2. Filter — Review returned profiles in batches. Short-list 5–10 per session who are genuinely relevant to the role, not just superficially close.
  3. Personalise — Write a message referencing something specific from their background (an open-source project, a conference talk, a blog post). Even two personalised sentences outperform a template blast.
  4. Cap — Maintain a hard limit of ~20 active outreach threads per manager at any one time. More than this generates follow-up debt that damages response rates and reputation.
  5. Track — Keep a simple log: who was contacted, when, and what response came back. Without tracking, conversations drop and candidates feel ghosted.

Time Allocation

  • 1 hour per week per hiring manager, not delegated entirely to recruiting
  • Manager-owned because engineers respond significantly better to outreach from a hiring manager than from a recruiter for senior roles — the signal quality difference is substantial
  • At typical response rates (~15–25% for personalised outreach), 20 active threads generate 3–5 conversations per week — enough to sustain a senior-role pipeline

What to Say (First Message)

  • Who you are: name, role, company — one sentence
  • Why specifically them: reference something real — their work, their background
  • What the opportunity is: one or two sentences
  • Soft call to action: “Open to a 20-minute conversation?”
  • Length: under 100 words

Generic recruiter messages are noise that engineers have learned to filter. LinkedIn’s own research shows personalised InMails achieve response rates ~15–30% higher than bulk outreach. A specific reference signals genuine interest rather than mass prospecting.

The Cap Rationale

Without an active-thread cap, managers start more conversations than they can sustain — leading to dropped follow-ups and eroded candidate experience. Twenty active threads is a deliberate constraint: enough to maintain pipeline velocity, few enough to sustain quality engagement on each one.

Connection to Candidate Strategy

Cold sourcing operationalises the Sourced channel of the Three-Candidate-Sources framework. It is the highest-effort, lowest-volume channel but produces the highest potential quality — making it most appropriate for senior and specialist roles where precision outweighs volume.
