Juicebox Reference Architecture

Juicebox Reference Architecture

Overview

Production architecture for AI-powered candidate analysis integrations with Juicebox. Designed for recruiting teams needing automated dataset ingestion from job descriptions, intelligent candidate scoring and ranking, result caching for repeated searches, and seamless export to ATS platforms like Greenhouse and Lever. Key design drivers: search result freshness, candidate deduplication across sources, outreach sequencing, and analysis pipeline throughput for high-volume hiring.

Service Layer

class CandidateSearchService {
  constructor(private juicebox: JuiceboxClient, private cache: CacheLayer) {}

  async findAndRank(criteria: SearchCriteria): Promise<RankedCandidate[]> {
    const cacheKey = `search:${this.hashCriteria(criteria)}`;
    const cached = await this.cache.get(cacheKey);
    if (cached) return cached;
    const results = await this.juicebox.search(criteria);
    const ranked = results.profiles.map(p => ({ ...p, score: this.scoreCandidate(p, criteria) }))
      .sort((a, b) => b.score - a.score);
    await this.cache.set(cacheKey, ranked, CACHE_CONFIG.searchResults.ttl);
    return ranked;
  }

  async exportToATS(candidates: string[], jobId: string, ats: 'greenhouse' | 'lever'): Promise<ExportResult> {
    const deduped = await this.deduplicateAgainstATS(candidates, jobId, ats);
    return this.juicebox.export({ profiles: deduped, destination: ats, job_id: jobId });
  }
}

Caching Strategy

const CACHE_CONFIG = {
  searchResults: { ttl: 1800, prefix: 'search' },   // 30 min — candidate pools shift slowly
  profiles:      { ttl: 3600, prefix: 'profile' },   // 1 hr — profile data stable short-term
  analysisRuns:  { ttl: 7200, prefix: 'analysis' },   // 2 hr — analysis results are expensive to recompute
  atsState:      { ttl: 300,  prefix: 'ats' },        // 5 min — ATS pipeline freshness for dedup
  outreach:      { ttl: 60,   prefix: 'outreach' },   // 1 min — sequence status changes frequently
};
// New search invalidates matching cached results; ATS export clears ats cache for that job

Event Pipeline

class RecruitingPipeline {
  private queue = new Bull('juicebox-events', { redis: process.env.REDIS_URL });

  async onSearchComplete(searchId: string, results: RankedCandidate[]): Promise<void> {
    await this.queue.add('analyze', { searchId, candidateIds: results.map(r => r.id) },
      { attempts: 3, backoff: { type: 'exponential', delay: 2000 } });
  }

  async processOutreachEvent(event: OutreachEvent): Promise<void> {
    if (event.type === 'reply_received') await this.flagForRecruiterReview(event);
    if (event.type === 'bounced') await this.markInvalid(event.candidateId);
    await this.syncStatusToATS(event);
  }
}

Data Model

interface SearchCriteria   { role: string; skills: string[]; location?: string; experienceYears?: number; companySize?: string; }
interface RankedCandidate  { id: string; name: string; title: string; company: string; score: number; skills: string[]; profileUrl: string; }
interface OutreachSequence { id: string; candidateId: string; jobId: string; steps: OutreachStep[]; status: 'active' | 'replied' | 'bounced' | 'opted-out'; }
interface ExportResult     { exported: number; duplicatesSkipped: number; atsJobId: string; }

Scaling Considerations

• Parallelize search requests across role categories — Juicebox API supports concurrent queries
• Cache analysis results aggressively — AI scoring is the most expensive operation per candidate
• Batch ATS exports by job requisition to minimize Greenhouse/Lever API round-trips
• Deduplicate candidates across searches before outreach to avoid double-contacting
• Rate-limit outreach sequencing to maintain sender reputation and deliverability

Error Handling

Prerequisites

• An approved architecture diagram, sandbox workspace, synthetic fixture set, source/destination allowlists, suppression controls, secrets references, and a tested rollback path.

Instructions

1. Validate each component in a sandbox with synthetic data; reject literal credentials, unapproved integrations, and any contact-level export.
2. Enforce least privilege, idempotency, redacted telemetry, suppression checks, and contacts_exported=0 before connecting a new component.
3. Run a staged canary and halt on scope, security, quota, policy, or retention drift; restore the prior component revision if it fails.
4. Promote only with owner approval and preserve only the redacted architecture receipt after cleanup.

Output

Produce an architecture receipt with component versions, environment, fixture classification, source/destination/suppression outcomes, no-export assertion, canary result, approver, retention/deletion proof, and rollback reference. Exclude diagrams containing secrets or contact data.

Examples

env=staging; fixture=synthetic; components=search,score,ats-adapter; suppression=pass; contacts_exported=0; canary=pass; rollback=release-r31 is a safe integration record.
