Technical Lead II, Frontend - Messaging Strategy

Engineering • Flex - Dublin, Ireland • POS-23538

At HubSpot, we’re on a mission to help millions of organizations grow better. Our platform supports marketing, sales, service and operations, and its product is built to be flexible, secure and empowering for both customers and our engineering teams.

The Messaging Product Group builds the apps and infrastructure behind marketing Email, SMS and WhatsApp. We power billions of messages per month and focus on building reliable systems while continuously innovating the product.

• 
  
• Lead a high‑impact frontend team building and evolving the core Marketing Email and SMS management experiences (dashboards, creation flows, send/review UIs, experimentation and related onboarding surfaces).
  
• Contribute high‑quality React/TypeScript code while guiding architectural decisions, reviewing designs and unblocking others.
  
• Own technical strategy for the team’s frontend surface area, including modular architecture, design system usage and cross‑app/library boundaries across Messaging.
  
• Partner in the leadership triad (with Product Management and Product Design) to set goals, sequence work and make trade‑offs that balance customer impact, reliability and iteration speed.
  
• Drive medium‑to‑large, multi‑quarter initiatives end‑to‑end, from problem definition and technical proposals through implementation, rollout and measurement.
  
• Champion reliability and service maturity for our frontend applications. Define SLIs/SLOs, improve performance (bundle size, latency) and keep the app inside our targets.
  
• Mentor and grow engineers on the team through design reviews, code reviews, pairing and 1:1s, providing clear and actionable feedback.
  
• Collaborate closely with backend and infra teams across Messaging to design reliable, observable front‑to‑back solutions that scale across channels.
  
• Help define and uphold engineering best practices across testing, accessibility, telemetry, experimentation and on‑call for our frontend services.
  
• Play an active role in hiring and onboarding new engineers and in representing HubSpot’s values and HEART culture throughout the interview process.
  

• 
  
• Deep frontend engineering experience (typically 7+ years) building complex, user‑facing web applications with technologies like React, TypeScript and modern JS tooling, ideally at SaaS scale.
  
• A proven track record as a technical lead or senior engineer leading at least 2–3 medium‑to‑large projects from design through production, with clear customer or business impact.
  
• Strong system design and architectural skills in the frontend, with the ability to break down ambiguous product problems, design clear interfaces and boundaries and make pragmatic trade‑offs between speed and robustness.
  
• Experience leading a small team or pod as a player‑coach, setting direction, coordinating work and helping others grow while still contributing meaningfully to the codebase.
  
• A strong sense of ownership over reliability and quality. You’re comfortable digging into performance issues, production incidents and test flakiness and driving them to resolution.
  
• Excellent cross‑functional communication skills with the ability to explain technical decisions to engineers and non‑engineers, write clear documentation and drive alignment across teams and time zones.
  
• A customer‑ and product‑oriented mindset. You’re motivated by improving marketers’ real workflows (not just shipping features) and you use data and feedback to inform decisions.
  

• 
  
• Experience in marketing technology, messaging, or communications products (email, SMS, WhatsApp, or similar).
  
• Background working on large‑scale, multi‑surface products where multiple UIs share libraries, design systems and infrastructure.
  
• Experience with performance optimization (bundle size, lazy loading, caching strategies) and service maturity / SLO‑driven development.
  
• Comfort working in environments with experimentation and AI‑powered workflows, or interest in learning quickly in this space.
  
• Prior experience in mentoring and developing senior engineers and in collaborating closely with EMs/TLs on promotions, feedback and growth plans.
