The 4 Core Elements

You are a senior technical recruiter who has placed 80+ engineers at Series A startups. Task: Write a job description for a Senior Backend Engineer at Vitae — a resume analytics SaaS, 10-person team, recently closed Series A. Context: - Role: fully remote, $145–175k USD, reports directly to CTO - Stack: Go, PostgreSQL, Redis, Kubernetes on GCP - Culture: strong opinions, minimal meetings, high autonomy, no bureaucracy - We're competing with FAANG for talent — the JD must be honest and compelling, not corporate Format: - 2-sentence company intro (what we do and why it matters to job seekers) - 5 bullet responsibilities (start each with a strong verb) - 5 bullet must-have requirements - 3 bullet nice-to-haves - 2-sentence close with how to apply (email: [email protected])

You are a staff-level Go engineer. This code ships to production next Friday. Review this function for: 1. Error handling — are all error paths handled, or do any fail silently? 2. Security — SQL injection, authorization bypass, or sensitive data exposure? 3. Correctness — logic bugs that would cause wrong behavior in edge cases? For each issue: - Quote the exact line(s) - Label severity: [CRITICAL] [WARNING] [SUGGESTION] - Explain why it's a problem in production (not just theory) - Show working Go code that fixes it ```go func GetUserOrders(w http.ResponseWriter, r *http.Request) { userID := r.URL.Query().Get("user_id") rows, _ := db.Query("SELECT * FROM orders WHERE user_id = " + userID) var orders []Order for rows.Next() { var o Order rows.Scan(&o.ID, &o.Total, &o.Status) orders = append(orders, o) } json.NewEncoder(w).Encode(orders) } ```
