Senior Conversion Tracking, API Engineer

This is a fully remote position, open to applicants in United States.

📋 Description

• Proactively identify implementation gaps, risks, and unverified assumptions prior to campaign launches.

• Compose implementation and QA summaries that are clear and actionable for non-engineers.

• Address queries in Slack promptly during working hours.

• Design, develop, and sustain client-side and server-side conversion tracking across Meta Pixel/CAPI, Google Ads API, Data Manager API, Enhanced Conversions and offline uploads, TikTok Events API, and other major platforms.

• Take ownership of signal design, event taxonomy, account and action routing, timestamps, value and currency, attribution windows, and data accuracy from landing page to ad platform.

• Create and manage integrations among client sites and forms, CRMs, call-tracking and scheduling tools, TNT infrastructure, and ad-platform APIs.

• Utilize webhooks, change data capture, OAuth, and queues with validation, idempotency, retries and backoff, dead-letter handling, replay and backfill, while ensuring complete audit trails.

• Implement and troubleshoot GTM, server-side GTM, Google tag and GA4, platform pixels, deterministic dataLayer events, first-party session IDs and cookies, URL propagation, and form injection across redirects, subdomains, SPAs, embedded forms, and booking tools.

• Maintain and validate advertising IDs, UTMs, and consent state throughout the funnel.

• Construct platform-appropriate payloads and matching logic, prevent double counting, manage adjustments and redactions, diagnose partial acceptance and attribution-window failures, and enhance match quality.

• Develop synthetic tests that reflect the real user journey from landing page through CRM and queue to the ad-platform UI.

• Reconcile data from sources, databases, CRMs, internal reporting, and platform counts; monitor match quality, attribution lag, and delivery failures.

• Generate evidence, alerts, runbooks, and incident updates; verify solutions post-launch.

• Produce clean, well-tested TypeScript across the stack, including API clients, webhook handlers, and event workers.

• Design and manage PostgreSQL schemas; write diagnostic SQL; optimize queries and indexes; plan data retention; trace data from ingestion to reporting.

• Leverage AI systems for debugging, code generation, documentation, and pattern recognition, ensuring the validation of generated work.

• Engage with Growth Managers, Client Success teams, client engineers, and platform support.

• Translate root causes, risks, evidence, dependencies, and ETAs into actionable updates.

• Take ownership of incidents through verification and follow-up.

• Develop reusable standards, runbooks, and guidance.

• Manage work in Git with a robust branching strategy, meaningful commit history, clean PRs, and collaborative review practices.

⛳️ Requirements

• Senior-level, hands-on experience with complex conversion tracking across Meta Pixel/CAPI and Google Ads API or Data Manager API, including Enhanced Conversions and offline conversions.

• Practical experience with browser and server-side instrumentation using GTM, server-side GTM or equivalent, Google tag and GA4, deterministic dataLayer events, SPAs, redirects, cross-domain and subdomain flows, embedded forms, and booking tools.

• Expertise in attribution identity and matchback, including GCLID, GBRAID, WBRAID, FBCLID, FBP, FBC, TTCLID, MSCLKID, first-party session IDs, cookies or URL propagation, consent state, and CRM persistence.

• Comprehensive knowledge of ad-platform payload semantics, such as event names, action source, account and action IDs, value and currency, timestamps and time zones, stable event or order IDs, browser and server deduplication, attribution windows, conversion adjustments or redactions, and partial-acceptance diagnostics.

• Experience in mapping CRM objects and lifecycle stages, integrating systems like HubSpot, Salesforce, Zoho, Attio, GoHighLevel, Typeform, or call-tracking platforms through webhooks, change data capture, and APIs.

• Proven ability to demonstrate end-to-end delivery with synthetic tests, platform diagnostics, source, CRM, database, internal-reporting, and ad-platform reconciliation, match-quality monitoring, alerting, incident response, and documented QA evidence.

• Experience in implementing consent-aware tracking and privacy controls under GDPR, CCPA, and ad-platform policies, including permitted PII collection, normalization and hashing exactly once, data minimization, and restrictions on sensitive categories.

• Strong understanding of API client design, REST and webhook integrations, OAuth and secrets management, change data capture, rate limits, partial failures, and inter-service communication patterns.

• Direct experience with message queues (RabbitMQ, BullMQ, SQS, or similar), encompassing idempotency, deduplication, retries and backoff, dead-letter handling, replay, and high-volume backfills.

• Proficient in TypeScript, ensuring clean, typed, testable, and maintainable code across API clients, services, and asynchronous workers.

• Strong fundamentals in PostgreSQL and ORM (Prisma, TypeORM, or equivalent), including diagnostic SQL, schema design, query and index optimization, and data retention.

• Solid knowledge of paid-media measurement: funnel and lifecycle event design, primary and secondary conversions, values, attribution windows, match quality, platform learning-volume tradeoffs, and channel differences across Meta, Google, TikTok, and related platforms.

• Strong Git skills, including branching strategies, PR workflows, code review participation, and version control discipline.

• Practical fluency with AI development tools and the discernment to validate their outputs; AI expertise should complement conversion tracking, API, and backend engineering proficiency.

• Excellent written and verbal communication skills in English, encompassing client-facing technical discovery, implementation documentation, incident updates, and evidence-based explanations.

• Additional experience with TikTok, LinkedIn, Microsoft Ads, or Reddit CAPI is highly desirable.
