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

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
• You don't want to collaborate closely with other areas of the business or engage with users when needed

What happens when you join us?

• You’ll own complex backend issues: Work closely with the Tech Lead to take on challenging backend problems and resolve them autonomously.
• You’ll debug, troubleshoot, and fix bugs: Solve real customer-impacting issues in our production environment, ensuring a smooth experience for our users.
• You’ll strengthen your backend skills: Work with cutting-edge technologies like Java Spring Boot, Hibernate, and SQL, and develop a strong foundation in backend development.
• You’ll collaborate and grow: Work with a talented and supportive team to analyze root causes, design solutions, and improve our backend systems.
• You’ll contribute to new features: Occasionally work on feature development as the team and product expand.
• You’ll live by our values:
  • We are obsessed with our customers.
  • We build smart.
  • We create trust
  • We are hacky.
  • We take ownership.
  • We are leaders of remote

Our Technology Stack

• Frontend: Typescript, Angular, Ngrx, Tailwind, Material UI
• Backend: Java SpringBoot, Postrgesql, Hibernate
• MDM product: Golang & Osquery
• Infrastructure: AWS with ECS
• Tools: Gitlab CI/CD, Figma, Slack, Notion, Gather.town, ClickUp

Interview Process

We aim to invite successful applicants to interview within a week and provide feedback after the take-home task stage.

Applicants can expect the following:

1. An Introductory call with a member of our talent team ~ 15-20 minutes
2. Take home task (scope: max. 1-2h) and technical interview with Tech Lead
3. Virtual on-site with the team and co-founders on Gather.town (approx. 2 hours)
4. Offer stage

After sending us your application in, please keep an eye out for an email from Grigory (CTO) or Chiara (People Ops). We will respond and move as quickly as possible.

What We Offer

• Remote Work: 100% remote work with a virtual office in Gather.
• Competitive Salary: Industry-competitive local salaries. We pay local rates that are at or above the market. We share this philosophy with GitLab.
• Equity: Generous equity package – we’re all owners of Secfix and beneficiaries of our collective success.
• Holidays: 26 days holiday + local public holidays.
• Health Insurance: Comprehensive health coverage.
• Development Budget: €1,000 annual personal development budget.
• Workspace Budget: Remote workspace budget and access to co-working spaces.

• Tech Equipment: Latest tech equipment (MacBook, monitors, headphones).
• Company Events: Company-wide events to build relationships and have some fun!
• Mentorship: We are backed by top VCs and accelerators and have direct access to world-class mentors.

Please note: We are an equal-opportunity employer and remote-only company. We work in sync using Gather as our virtual office. As a small fast-growing company, we believe in the need for an in-sync component of daily communication and therefore cannot support 100% asynchronous work.

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.

• Extensive experience with ReactQuery for efficient data fetching and state management
• Advanced knowledge of Typescript, including complex type definitions and best practices
• Expertise in modern CSS frameworks, particularly Tailwind CSS
• Demonstrated experience in monorepo architecture and management
• Strong understanding of CI/CD principles and experience implementing robust pipelines

Technologies we use and teach:

• React.js, Vue.js, Web3 Tooling, Typescript, GraphQl, NodeJS

Benefits

Join a small yet mighty team of industry veterans focused on revolutionizing crypto market making, collaborating with major projects like MakerDAO, Uniswap, Aave, Lido.
