Technical Lead II, Frontend - Messaging Strategy
POS-23538
At HubSpot, we’re on a mission to help millions of organizations grow better. Our platform is used by businesses worldwide to manage their marketing, sales, service and operations — and under the hood, our product is built to be flexible, secure and empowering for both our customers and our own engineering teams. We believe in autonomy, curiosity and building a workplace where everyone can thrive.
Meet the team: Messaging Strategy Frontend (Messaging Product Group)
The Messaging Product Group builds the apps and infrastructure behind marketing Email, SMS and WhatsApp in HubSpot. We work at a serious scale, powering billions of messages per month. We focus on building reliable systems while continuously innovating the product to help our customers achieve better outcomes.
Messaging Strategy Frontend builds the core customer-facing experiences that marketers use every day to create, manage and publish marketing emails and SMS. This is where marketers plan campaigns, iterate on content and make decisions that directly impact their results, across journeys that need to scale and adapt as customers grow with HubSpot.
As a Tech Lead II, you’ll be a player-coach for this space, setting technical direction, shaping product execution and helping a small team deliver high-quality experiences that marketers rely on every day.
What You’ll Do
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.
What you’ll bring
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.
Nice to Have
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.
