The traditional model of siloed product managers, designers and engineers is too slow for AI-native development. At HighLevel, every engineer owns a product outcome end to end, from idea to prototype to production to scale. You will operate as a Team of One. With AI tooling and strong engineering infrastructure, one engineer can now build what used to take a whole squad. You wont be implementing tickets. Youll own the product.
About the Team
The Email team owns the Email platform behind HighLevels email experience, which poweM+ emails a day. We own the full path from compose to inbox, so the reliability, speed and quality of what we ship directly decide whether emails from over a million businesses land in the inbox.
We are responsible for:
- Email Platform: The Vue.js apps used to design, compose and send emails, plus the Node.js/NestJS services behind them.
- Sending Infrastructure Deliverability: IP pools, dedicated IPs, dedicated domains and shared domain pools. These let new users send from day one, while we stay accountable for getting their email into the inbox.
- API-First Platform: Every capability is exposed through APIs, so email can be built into any product or workflow that needs it.
- Scale Reliability: Keeping throughput high at peak load, with high uptime and send success rates.
- Email Statistics Analytics: Integrating email stats with internal teams and making every release measurable on our dashboards.
- AI in Email: Bringing LLM-powered capabilities into email creation, while weighing token cost, latency and quality
Impact Scale
Email is one of the most critical channels on HighLevel. When it works, businesses grow; when it breaks, their customers stop hearing from them. Thats the weight this role carries.
- Businesses: Every one of the 1M+ businesses on HighLevel relies on email to reach their customers.
- Sub-accounts: Your work runs across 1.6M+ sub-accounts, from solo operators to agencies managing hundreds of clients.
- End users: What you ship reaches end users through 1.2B+ emails every month.
- Volume: 40M+ emails a day flow through the systems youll own, so a 1% gain in reliability or deliverability affects hundreds of thousands of emails daily.
- Blast radius: One change can affect every business on the platform at once, which is why we care so much about reliability, data integrity and security.
How we work
- Iterate fast: Go from idea to prototype to production in days, not quarters. Ship small, measure, learn and improve.
- Use AI well: Use AI across the whole cycle (design, coding, testing, reviews and debugging) to move faster without lowering the quality bar, and pick the right model for each job based on quality, latency and cost.
About the Role
Responsibilities
Feature Module Ownership
- Translate business goals into working, deployable systems.
- Propose architecture, data models, workflows and implementation plans for your modules, then refine them with Tech Leads and Engineering Managers before you build.
- Own modules end to end: design, release, post-launch stability and ongoing improvements.
- Design clean, versioned, well-documented APIs as a core part of every feature, so the platform can be integrated wherever its needed.
Rapid Prototyping Iteration
- Turn ambiguous ideas into working demos quickly, using AI to build and iterate fast.
- Validate through experiments and real user feedback, then iterate to production quality.
- Drive feature attribution and metrics visibility so every release is measurable.
Scale, Performance Reliability
- Build and maintain the Email ecosystem, designing for scalability, reliability and data integrity at 40M+ emails/day.
- Evolve our sending infrastructure, including IP pool management, dedicated IPs and domains, and shared domain pools, to protect sender reputation and maximize inbox placement.
- Build robust error handling: idempotent processing, retries with backoff and graceful degradation.
- Optimize frontend rendering, component architecture, lazy loading and state management. Tune backend queries, caching (Redis/CDN) and latency at scale.
- Design data models and analytics on ClickHouse, MongoDB and Firestore.
- Reason through token consumption, inference cost and infrastructure tradeoffs when integrating AI and LLMs.
Engineering Quality Security
- Practice test-driven development and hold a high bar for automated test coverage.
- Build securely by default: authentication, secrets management and safe handling of customer data and PII.
Operational Excellence
- Instrument systems with monitoring and telemetry.
- Build evaluation loops for continuous quality improvement.
- Automate workflows that increase engineering velocity.
- Keep documentation clear and repeatable.
Requirements
- 4+ years building and running production systems, including owning them when they broke
