Technical Lead II – Frontend

Description

• 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.

Requirements

• 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.
