About Us:

Blockworks is an information platform that sits at the center of the crypto industry. We transform raw, complex data and facts into actionable research, trusted news, alpha-driven insights, and world-class events. The result is transparency and confidence. We enable investors, operators, and institutions to see past the noise, make better decisions, and drive the industry forward.

Who You Are:

Software engineering is your passion, and you have a keen focus on backend and API development. You are a player-coach and a natural leader who understands the technical and human elements that go into great software design. You have a results-oriented attitude and a passion for delivering flawless releases and developing digital product pipelines (CI/CD pipelines). You have a proven track record of facilitating engineering teams to increase productivity and quality.

You're excited about the possibility of being on the ground floor of the design and development of backend data strategies. You bring a passion for designing and maintaining scalable API services that handle large amounts of data elegantly. You love moving quickly in a fast-paced start-up, but you also bring intentionality, sustainability, and scalability to your approach as an engineer.

What You’Ll Do:

As our Senior Backend Engineer on the data team, you'll be responsible for designing and building the backend systems and strategies that will power all of our data and analytics products. You'll work collaboratively with other members of the engineering team to design, develop, implement, and evolve our data strategies and approaches.

Every day will look a little different, but in general, you will do things like:

Build and Ship: You'll be responsible for building our backend data structure and APIs for our core products, and on our Engineering team, we ship fast and often (but never at the expense of quality).
Own the API: You'll be in charge of building, evolving, and maintaining our backend API layer that fuels our current and future crypto analytics products.
Proactively Identify and Fix Issues: In partnership with the rest of the Data Engineering team, you'll constantly be on the lookout for stability and scalability issues.
Engage in Product Development: You'll participate and bring technical leadership to all aspects of our product development life cycle
Scope and Spec Improvements: You'll be responsible for estimating the development scope and building specs for the implementation and rollout of system changes.
Drive Operational Efficiency: You'll be constantly on the lookout for opportunities to improve workflows, reliably automate routine tasks, and identify and mitigate project risks.
Cross-Functional Collaboration: You'll work with other teams across Blockworks, including Research, Product, and Engineering, to lead initiatives and move forward with program collaborations.

Experimentation is frequent at Blockworks. Comfortability with being uncomfortable is a must.

What You’Ve Done Before:

For this role, first and foremost, you must have significant knowledge of the crypto industry; interest in crypto is not enough, we’re looking for someone who considers themself crypto native. You have a deep understanding of data principles and architecture that either came from a Bachelor's degree in Computer Science, Engineering, or a related field or from intensive hands-on work experience. You have a minimum of 5 years of professional experience as a Backend Engineer, with a strong focus on backend development and API architecture using Typescript and Node.js or Go. You've got demonstrated experience building blazing-fast API endpoints that can handle large amounts of data with over 1M requests per day.

You also bring significant experience maintaining and running API endpoints using serverless architecture, including deployment, configuration, and TTFB optimization. You bring proficiency in designing and optimizing relational databases, such as MySQL and PostgreSQL, including data modeling and query optimization. Lastly, but perhaps most importantly, you've got incredibly strong problem-solving and engineering skills that showcase your attention to detail and foundational ability to write and maintain clean and reusable code.

It’D Be Great If You’Ve Done This:

Experience and demonstrated success in crypto, web3, startup or incubator environments will move you to the top of the list. Having a background in caching mechanisms and tools like Redis to enhance application performance and scalability may also set you apart from other candidates. Lastly, we're looking for excellent communicators and collaborators who are as much at home working in cross-functional teams as they are writing code.

Salary, Benefits, & How We Work:

This is a full time exempt position with an expected salary of $160,000 - $200,000/year.

Benefits:

Remote-First:

We're a remote-first organization with an office in NYC for you to utilize as you please.

Company Description

Welcome to the good side of tech 👋

You might have heard about us, but with a different name: ZnanyLekarz. It all started 10 years ago when we asked ourselves: is anyone in healthcare thinking about patients? We jumped in and we empowered patients by giving them access to leave and read reviews about their visit. We then provided doctors with the technology to manage bookings easily and save time, so they could devote themselves to what they always wanted: treating patients. And today is the day in which we ask you: wanna join us in the next step of making the healthcare experience more human?

Docplanner At Scale

We are leaders in 13 countries so far, and more than 90 million patients trust us every month. 300.000+ specialists believe in us and our product, and so do leading venture capital funds such as Point Nine Capital, Goldman Sachs Asset Management and One Peak Partners. And yet, employing over 2.500 people all over the globe, we managed to keep the startup-mindset we started with over 10 years ago.

We believe that taking the diversity of human experience into account makes a better healthcare experience for all . We’re not just different: we embrace diversity. We will encourage you to come to work your whole self, and that includes not coming to the office at all if you prefer not to, as we're 100% remote-friendly.

Why join us?

Working at Pleo means you're working on something very exciting: the future of work. Our mission is to help every company go beyond the books. Pleo itself means ‘more than you’d expect’, and it’s been the secret to our success over the last 8 years. So it’s only fitting that we’d pass this philosophy onto our customers to help them make the most of their finances.

We think company spending should be delegated to all employees and teams, that it should be as automated as possible, and that it should drive a culture of responsible spending. Finance teams shouldn’t be siloed from the rest of the organisation – they should work in unity with marketing, sales, IT and everyone else.

Speaking of working in unity, our values tell the story of how we work at Pleo. We have four core values, the first of which is ‘champion the customer’, which means we address real pain points that businesses face. Next up is ‘succeed as a team’, which highlights how our strength lies in our diversity and trust in each other. We also ‘make it happen’ by taking bold decisions and following through to deliver results. Last but not least, we ‘build to scale’, creating lasting solutions that address today’s challenges and anticipate tomorrow’s needs.

So, in a nutshell, that's Pleo. Today we are a 850+ team, from over 100 nations, sitting in our Copenhagen HQ, London, Stockholm, Berlin, Madrid, Montreal and Lisbon offices —and quite a few full-time remotes in 35 other countries! Being HQ'd out of Copenhagen means we're inspired by things like a good work-life balance. If you don't work in the office with us, we'll help you set up the best remote setup possible and make sure you still have time to connect with your team.

Stories have the power to make the ordinary extraordinary. They help us think bigger, see beyond ourselves, and deepen our connection with others.

As one of the world’s leading audiobook and e-book streaming platforms, Storytel brings unlimited listening to millions of users across 25 markets. Driven by our purpose, “Leading the future of storytelling, we move the world through stories”, Storytel Group inspires and entertains people around the world by blending innovation with tradition. We bring stories to life across various formats for everyone to discover. Anytime. Anywhere.

Ready for your next chapter? We’re looking for a Senior Backend Engineer to join our Content Platform team!

About The Team

The Content Platform domain is the backbone of Storytel, ingesting and processing all content from publishers to the platform, enriching it with metadata, and building systems that organize knowledge about creators and content. Over three million audiobooks, ebooks, and podcasts flow through our processing pipeline and are made available to other teams via APIs and event streams.

The domain mission is to be a key driver for Storytel’s product and commercial strategy by making book metadata a competitive advantage for Storytel. The team leverages AI and automation to scale the creation and enhancement of book metadata, fueling product innovation and unlocking the full potential of generative AI-powered experiences.

About The Role

Take the next step in your career as a Senior Backend Engineer at Storytel! You’ll work with cutting-edge technologies alongside other experienced colleagues. As a senior backend engineer, you’ll be involved in – and be asked to lead some of – our modernisation journey, but also the maintenance of the existing platform. Your skills and experience will also be valuable in supporting and coaching more junior engineers.

About You

To be a good match for this role, we believe that you have:

Solid knowledge of backend development in Java, and experience of more polyglot environments – today we maintain services in mostly Java, but even some in Golang, Kotlin, and C#.
A great understanding of modern architecture, system design, data structures, and software engineering principles, and knowing how to apply them to design scalable and robust solutions.
Experience with deploying and operating services in a cloud environment (we use Google Cloud Platform, but experience from other platforms is just as valuable).
A curious and positive mindset about the potential of LLMs, both as a tool to enhance your own workflow and as a component for building innovative product features.
Experience working closely with business and product stakeholders, and understanding their needs. You can transition from the idea stage to scalable and maintainable solutions.
Passion for building great products that people love, always making technology choices with this end goal in mind.

But most importantly, we believe that the right mindset and attitude are more valuable than ticking all the technical boxes, so if you feel that this could be the right job and environment for you to learn and develop yourself, alongside others in the team, do not hesitate to get in touch with us!

Join A World Of Stories

At Storytel, we’re a team of creative story lovers who thrive on collaboration and new ideas. Our workplace is friendly, dynamic, and full of opportunities to experiment and make an impact. We believe in trust, flat hierarchies, and empowering you to grow with us.

Does this sound like your next story? Simply fill out the application form and share your CV or LinkedIn profile – no cover letter needed. Answer a few questions, and you’re all set.
