Hi! I'm Erez. I run ZSA. We're a small company making good keyboards. We're fully distributed, with people from Thailand, South Africa, the US, Canada, Croatia, and more.
You, I hope, are not a ninja, nor a rockstar. I hope you're a nice person, and also a good programmer with an eye for detail. You can be from anywhere in the world.
Things I hope you're very good at
- Communicating in writing.
- Learning new things.
- Working with AI dev tools in a sane way, and sharing your workflows.
- React (bonus if you know mobX State Tree).
- CSS (Sass and/or Styled Components)
- Rigorously QAing your own work
- Asking good questions
What's good about this job
You will be primarily responsible for ZSA.io and typ.ing. ZSA.io a custom-built eCommerce site (next.js). Shopify has featured it in several keynote presentations alongside brands like Allbirds. Typ.ing is a next-gen typing trainer, clean and fun.
Because we're so small, your work is going to make a big difference. We don't have a QA tester — you will QA your own work. That's why attention to detail is so important.
Things we don't do:
- We don't have daily standups. We have meetings when we need them.
- We don't do any sort of invasive employee monitoring like time or activity tracking.
- We don't have investors, so we only think about our customers in everything we do, not about "shareholders".
- We don't advertise or work with influencers (read more on our Why Trust Us page).
- We don't obsess over analytics and funnels. We talk to real people and value qualitative feedback to guide our work.
Things we do:
- Trust the team.
- Work together. Collaboration is tight, over text (Telegram is our platform of choice).
- Specify work accurately, ahead of time, with high-fidelity mockups in Figma and well-defined written work items.
- Have clear acceptance criteria ("definition of done").
- Review every PR.
- Care about tech debt and take the time to address it.
How the hiring process works
If this role sounds interesting, please fill out our questionnaire, linked below. Please do not email me a resume.
If you seem like a good fit, I will reach out (me, personally — not some HR person or a hiring team). Then we'll have a call.
If after the call we both want to proceed, you will do a short, paid test project (two weeks).
If after the test project we're both still happy, you will begin a fully paid trial period. This is two months with ZSA, working with the whole team, drawing full pay, doing real work.
If after the trial period we're all happy, you will become a full-fledged member of ZSA. Once that happens, turnover is typically exceedingly low — people tend to stay and grow with us for years.
Thanks for getting this far,
Erez

About Us
Close is a bootstrapped, profitable, 100% remote, ~100 person team of thoughtful iniduals who value autonomy and impact. We’re eager to make a product our customers fall in love with over and over again.
We ❤️ small scaling businesses. Since 2013, we’ve been building a CRM that focuses on better communication, without the hassle of manual data entry or a complex UI. We are out to supercharge sales productivity with the most modern, thoughtfully all-in-one, AI-powered, and communication-focused CRM.
Our app’s frontend is a single-page TypeScript web app mostly written in React (originally built with Backbone.js). Our mobile app is built using React Native. We bundle with Vite and target only modern browsers. We test with Vitest, React Testing Library, Playwright, and Chromatic (VRT). Our UI updates in near real-time and is styled via CSS modules and takes advantage of fun technologies like Websockets and WebRTC.
We care about performance (e.g. route-based code splitting or skeleton UI), maintainability, and testability of our frontend code. Our product development process is inspired by Shape Up. We sweat the UI/UX details and work collaboratively with the Product team throughout the design process. This means ing into lo-fi wireframes, and communicating continuously when those ideas are brought to life using Figma and code (Storybook).
Our frontend app is built on top of our REST API & GraphQL endpoints. Our backend tech stack consists of Python/Flask, MongoDB, Postgres, Elasticsearch, and Redis. We run our services in Docker on AWS.
We ❤️ open sourcing our code and ideas on our GitHub and on The Making of Close, our behind-the-scenes Product & Engineering blog. Check our projects such as react-custom-scroller, use-infinite-scroll, use-abortable-effect, and smart-tooltip-delay or insights from our day-to-day work on such as Under the Hood: Developing Close's AI-Powered Call Assistant, Cutting our Lead page LCP by half, and Highlights From a Complex Downshift.js Refactor.

Why should you join Secfix?
Secfix is an early-stage fully remote startup in the best sense of the word. We’re a fun, close-knit team on a mission to automate security and compliance for modern companies and become the European compliance automation leader. We rapidly grew from just three founders to 20 people in less than 2 years after founding.
Your work will significantly impact our tech product used by CTOs, engineering teams, COOs and the whole team will celebrate your wins.
In comparison to many startups we are growing the team at a healthy rate and there is a balance between fast growth and maintaining our runway as we scale. Most of our costs are already covered by revenue.
With new challenges (we're looking to 2x the team next year), you're assured of growth and progress. Our trajectory is fueled by top investors, including Octopus Ventures, Neosfer (Commerzbank), founders of Signavio and many more angels.
Who are we looking for?
We're building an environment at Secfix where ambitious, independent engineers can thrive. We want to grow with people who take pride on building and maintaining actual products, who are curious about how the features we ship are used daily to solve real challenges, and who'll use their in-depth engineering insights to push the envelope on what we can achieve together. We own products and outcomes, not Jira tickets.
Bring your commitment and drive to grow, and we’ll deliver an environment that keeps you happy, healthy, and empowered to do your best work with us.
Scope of this role: 90% backend troubleshooting, 10% new feature development.
Experience that you will ideally bring
- 1+ years of experience in Backend Engineering through first full-time job and internships.
- Solid foundation in object-oriented programming with Java.
- First professional production experience in Java Spring Boot, Hibernate, and SQL.
- Familiarity with 3rd-party APIs and interest in learning monitoring and troubleshooting.
- Willingness to take ownership of tasks, collaborate, and adapt to feedback.
You should apply if:
- You’re ambitious, independent and growth-oriented.
- You bring young talent to our team with at least 1 year of equivalent experience.
- You have strong engineering fundamentals, code efficiently, and you know what you're great at and what you're less great at.
- You thrive when you have autonomy, own as many of the details as possible, and project manage your own work.
- You’re comfortable collaborating and communicating in a remote environment, especially in writing and on video calls. You understand that working remotely doesn't mean working alone. Remember, it requires more pro-active communication than working in the office.
You should not apply if:
- You need a lot of processes to tell you what to do or you're comfortable only picking up highly detailed tickets from a JIRA board
- You only want to write code and don’t really care about the bigger picture and customers
- You don’t want to test, deploy, monitor and troubleshoot your own code
- You don’t want to lead your own projects, but rather be led by someone else

We believe in a world where every organization, from a small startup to a large enterprise, will be tokenized and traded onchain. For this world, Arrakis is building the tools to create the necessary liquidity to enable this token economy to rival and out-compete the traditional financial industry.
DeFi is at risk itself of being overcome by centralised actors however. As Ethereum’s DeFi ecosystem has become more complex, sophisticated actors have extracted more and more value known as MEV. Arrakis is working on next generation solutions at the speartip of the MEV supply chain, such as HOT AMM, to protect LPs and token issuers against this value extraction.
As one of the Front End engineers at Arrakis, we’re looking for someone who is hands on but also has strong product thinking skills.

Requirements
- Strong proficiency in React and Next.js ecosystems
- Hands on experience with Web3 technologies (wagmi, viem, Rainbowkit)
- Extensive experience with ReactQuery for efficient data fetching and state management
- Advanced knowledge of Typescript, including complex type definitions and best practices
