Sensor Tower’s insights are trusted by more than 2,500 enterprises worldwide across tech, retail/commerce, entertainment/media, gaming, consumer packaged goods and finance.
Role Summary:
As a Frontend Engineer at Sensor Tower, you will not only build features, you will define how we build them. You will take ownership of major technical components, ensuring our applications are scalable, maintainable, and fast. In our lean and flat organization, your voice will shape the technical direction of our product, helping us deliver an intuitive, fluid user experience that helps our customers understand the digital ecosystem.
Fulfill your potential with us:
- Architect and deliver complex, scalable frontend systems that are simple and effective, removing unnecessary complexity from our codebase.
- You will partner with Product Managers to co-author requirements and shape the scope, ensuring engineering feasibility is considered during ideation, not just execution.
- Lead technical decision-making for medium-to-large scoped features, taking responsibility for the successful delivery of value to the customer, not just the completion of tickets.
- Mentor junior and mid-level engineers through code reviews, pair programming, and by instilling quality-first habits across the team.
- Take ownership of the frontend stack by proactively identifying bottlenecks, technical debt, or systemic issues and driving the initiatives to fix them.
- Advocate for and drive best practices in React, TypeScript, and web performance optimization across the engineering organization.
- Collaborate deeply with Data Science and Backend Engineers to ensure seamless data flow and end-to-end system reliability, and use these partnerships to progressively expand your expertise across the full stack.
What we are interested in:
- 4+ years of software engineering experience with a deep specialization in modern JavaScript, TypeScript, and React.
- Proven ability to architect complex state management. While our stack relies on TanStack Query, React Router and Zustand, we value engineers who understand the principles and can adapt expertise from other libraries like Redux, MobX, NextJS.
- You can design systems that handle complexity without becoming complicated, prioritizing long-term maintainability.
- Experience elevating the skills of peers. You don't just review their code; you teach patterns and best practices.
- Competence in writing robust and efficient unit and integration tests using frameworks like Jest or Playwright.
- Deep understanding of web performance, browser internals, and optimization techniques for data-heavy applications.
- A "Product Owner" mindset. You care deeply about the "why" behind every feature, viewing code as a tool to solve real user problems. You are comfortable pushing back on requirements and proposing alternative solutions that drive better business outcomes and user experiences.
Extra Credit:
- Experience in data visualization and analytics (handling large datasets, heavy DOM manipulation with libraries like Highcharts).
- A portfolio, GitHub history, or technical writing that demonstrates clean code, an eye for design, and the ability to solve complex architectural challenges.
- Familiarity with back end frameworks Ruby on Rails/Angular and different types of DBs (Clickhouse, Mongo, Postgres)
- Knowledge of AI-driven coding tools and models as we encourage leveraging AI to enhance coding efficiency and unlock creative potential

JTX is our trading app, and it runs on the fastest market infrastructure on Solana, which we also built. What nobody has done yet is make that speed something a trader can feel. That is this job.
JTX is live. Two frontend engineers built it to this point and you would be the third. The work now is one to a hundred: harden what exists, make it hold up under real volume, expand onto mobile, and raise the ceiling on every screen a trader touches.
We're a small team with product-market fit. That means:
High ownership: every team member drives significant technical decisions and shapes our product roadmap.
Fast execution: we ship rapidly and iterate based on real-world feedback. Progress, not motion.
High quality bar: the details are the product. We don't trade them for speed.
About the Position
You'll own the surface of JTX across web and mobile: order entry, market data, charts, positions, execution quality, onboarding, and the wallet flows underneath all of it.
The role suits a generalist with strong taste. You'll partner with design, product, and the infrastructure team, and you'll make architectural calls that stick for years. If you've spent time thinking about how markets actually work on Solana and want to build the product layer on top of that, this is the role.
Stack: React 19 + TypeScript on Next.js. Jotai + TanStack Query. Tailwind with a token-based design system. TradingView Advanced Charts on our own datafeed. Privy wallets. WebSockets to our engine. Web ships as a PWA; native mobile apps are in development.
What's Hard Right Now
Data freshness: several live WebSocket streams (order book, trades, candles, stats) feed many panels at once; keeping them fast, consistent with each other, and honest through async gaps (stale quotes, pending fills)
Performance: a data-dense terminal that stays smooth under constant streaming updates, including on mid-range hardware
Security: wallet signing, session auth, strict CSP, hardened supply chain
Shipping volume: three engineers own the entire surface of a live exchange; the backlog is bigger than the team, so throughput and prioritization are part of the job
Keeping product behavior and design language consistent between web and mobile while being very attentive to nuances of each mobile platform
Making execution quality something a trader can see in a glance instead of something they take on faith
What You'll Do
Build and own the JTX client across web and mobile
Ship real-time trading interfaces: order books, charts, order entry, positions, fill and execution visibility
Hit tight latency and render budgets against streaming market data, and decide what belongs on the client versus the server
Build wallet and signing flows, including self-custodial and embedded wallet onboarding
Own the shared component, state, and data layers the rest of the product team builds on
Make architectural decisions that hold as the codebase, the team, and the user base grow by an order of magnitude
Ship fast, watch real users, iterate
What We're Looking For
Attention to detail bordering on obsessive. You can look at a screen and say what is wrong with it, and it bothers you until it's fixed.
5+ years building production frontend, including something real-time, data dense, or financial
Deep React and TypeScript. You can explain why a component re-rendered and then fix it.
Mobile experience: React Native, Expo, or native iOS and Android
Strong fundamentals: browser performance, memory, websockets, network behavior under load
Security-first instincts around signing flows, key handling, and what should never touch a log
Comfortable in a codebase that is already live. You can refactor and clean up without stopping shipping.
Able to weigh business and engineering tradeoffs, and to explain complicated things simply
Relevant Background
If you have experience in any of the following, you may be a good fit:
Trading terminals, exchange or brokerage frontends
Consumer fintech apps at scale
Charting, time series, or high-frequency data visualization (canvas, WebGL)
Solana or EVM app development, wallet integrations, transaction signing
Maintaining a public TypeScript library or design system
Задачи:
- Разрабатывать новый функционал продукта и участвовать в запуске новых проектов.
- Реализовывать pixel-perfect интерфейсы по макетам Figma, соблюдая дизайн-систему и высокие стандарты качества.
- Работать со сложной бизнес-логикой, улучшать архитектуру приложения, заниматься рефакторингом и поддержкой существующего функционала.
- Писать unit- и integration-тесты, самостоятельно проверять качество реализованных решений.
- Оптимизировать производительность приложения, улучшать SEO и участвовать в развитии продукта вместе с дизайнерами и командой разработки.
Требования:
- Коммерческий опыт разработки на React и Next.js в продуктовой компании.
- Отличное знание TypeScript, включая generics и строгую типизацию.
- Опыт работы с App Router и React Server Components.
- Опыт работы с react-hook-form, Zod и Zustand.
- Опыт разработки в рамках дизайн-систем и работы с Figma.
- Опыт оптимизации производительности (Core Web Vitals, rendering, bundle size) и понимание принципов SEO.
- Опыт написания unit- и integration-тестов.
Будет преимуществом: Stripe, Coinflow; Web3 / Solana; next-intl; Feature-Sliced Design (FSD); epub.js; Google Tag Manager, GA4, маркетинговые интеграции и аналитика.
Условия:
- Полностью удалённая работа.
- Оплата в валюте. Оформление по b2b контракту.
- Гибкость, минимум бюрократии.
- Небольшая команда, где ваш вклад заметен.
Сейчас ищут Junior Frontend-разработчика с навыками React и TypeScript, а также Junior Backend-разработчика с навыками Node.js и TypeScript.

Perplexity is looking for a Design Engineer to help turn perplexity.com http://perplexity.com into a real growth engine, not a pile of one-off pages. You'll sit shoulder to shoulder with brand designers, PMMs, growth, and content teams, shipping product launch pages, campaign landing pages, and the components and tooling that let those teams move fast without lowering the bar.
This is a hands-on role for someone with real taste, sharp attention to detail, and the speed to turn a Figma file, a Slack thread, or a rough sketch into a polished, shipped page quickly.
Tech stack: React, TypeScript, Tailwind CSS, Sanity
WHAT YOU'LL DO
- Ship product launch pages and evergreen marketing pages for products like Comet, Computer, Deep Research, Search, and Hub. Own the work from Figma handoff to production.
- Partner with brand designers to build interactive experiences that make the site feel alive and drive engagement.
- Maintain and extend our brand design system and component library, keeping Figma and production in sync so brand and creative can scaffold pages with guardrails.
- Work closely with the paid ads and growth teams to run A/B tests on landing pages, popups, and upsell modules. Read the results, then iterate.
- Migrate the leftover Framer collections to Sanity, model schemas that non-engineers can actually use, and help ship new content types like changelog, customer stories, and academy pages.
- Design and unblock yourself when design resources are constrained. You can take a rough direction and turn it into something worth shipping.
- Improve the tools around the work: CMS workflows, i18n, SEO, experimentation, and internal tooling for marketing self-serve. If a manual process is slowing the team down, you should want to fix it.
WHAT YOU NEED
- 3+ years of experience as a front-end or design engineer, ideally on a marketing or growth site.
- A portfolio site that shows your previous work on marketing sites and design work.
- Strong skills in React, CSS, and modern frameworks.
- Deep understanding of responsive design and design-to-code workflows. You know what the platform can do and you stay current on what's new.
- Experience maintaining a reusable component library and sweating the design details in code.
- A real eye for design. You can tell the difference between "almost right" and "actually right," and your work reflects it.
- Attention to detail that shows up unprompted. The 2px misalignment, the wrong easing curve, the widow at the end of the paragraph.
- Stellar communication skills and a track record of working effectively in cross-functional teams. You can defend a decision, push back constructively, and explain trade-offs to non-technical stakeholders.
- Desire to work in a fast-paced environment, continuously grow, and master your craft.
NICE TO HAVE
- Experience running A/B tests and reading experiments results in a growth context.
- Knowledge of SEO principles, structured data, and localization workflows.
- Experience with web animations (GSAP, Motion, Web Animations API), 3D libraries, or interactive storytelling.
- Experience working with a headless CMS (Sanity, Contentful).
- Experience building internal tools or AI-assisted workflows that made a marketing or design team faster.

- Stellar communication skills and a track record of working effectively in cross-functional teams. You can defend a decision, push back constructively, and explain trade-offs to non-technical stakeholders.
- Desire to work in a fast-paced environment, continuously grow, and master your craft.
NICE TO HAVE
- Experience running A/B tests and reading experiments results in a growth context.
- Knowledge of SEO principles, structured data, and localization workflows.
- Experience with web animations (GSAP, Motion, Web Animations API), 3D libraries, or interactive storytelling.
- Experience working with a headless CMS (Sanity, Contentful).
- Experience building internal tools or AI-assisted workflows that made a marketing or design team faster.
