Hiring from: European timezones

Category: Software Dev


What makes the dev team at Silverfin special?

  • First of all, we build a hell of a product and our customers love us. Even our customers’ customers love us. Silverfin solves a very real problem: it automates a large chunk of the repetitive tasks that people working in financial services spend their time on, and improves communication with their customers.

  • To give you a sense of scale: our database exceeds 3TB in size*, and our largest table recently crossed the 8 billion row mark. We interface with more than 30 different external APIs, and provide third parties an API of our own.

  • We’re a remote-first engineering team with offices in Ghent, London and Copenhagen which you can visit if you’d like. Still, most of us work remotely, even those who are local. We’re based all over Europe, and without Slack we’d be lonely, now we just zap in and out of the zone as we wish. Or not: we encourage judicious use of the DnD function, and recommend async communication over disturbing synchronous pings.

  • We’d be really happy to welcome you in our #dev channel, but it’s not just virtual: we make sure we regularly get to see each other IRL too. Twice a year we fly the whole engineering team together to a different location in Europe, and at least once a year we join up with the rest of the company to not become too siloed.

What does working at Silverfin look like?

  • We work in small, focused teams of around 5 people, each team taking ownership of a part of the application. When developing new features, the team is responsible for both the backend as well as the frontend part.

  • You’ll be supported by our crazy good UI designer who writes HTML and CSS components into a reusable UI-kit, and even builds Vue prototypes where necessary, handling compatibility problems with different browsers for you, and making sure everything is responsive too.

  • On the other side of the spectrum is our genius ops team who keeps things running smoothly, making sure deploys happen correctly, and will work with you when issues should arise.

  • Our stack is Vue.js and vanilla JS with a sprinkling of jQuery on the frontend and an up-to-date Rails monolith on the backend. We use PostgreSQL and Redis for persistence and caching, and everything is running on a Kubernetes cluster in Google Cloud. We use GitLab, Quip and Slack for everyday tasks and Zoom as our remote conferencing tool of choice. No code gets deployed without a thorough code-review by a peer, testing is a must, our sprints are called cycles and last 3 weeks, and sometimes we even finish everything that we committed to in time.

What are we looking for? 

We’re looking for somebody who’s really great at developing in Ruby and Ruby on Rails.

  • You need to be experienced in both Ruby and Rails, and also know where the boundaries lie between them. You need to be able to code in Ruby without any of Rails’ training wheels.

  • You enjoy mentoring juniors and giving in-depth feedback during code reviews. While you appreciate the small stuff, you recognize bikeshedding and can avoid its pitfalls.

  • You code with reason and can justify the important decisions you made during development.

  • You know and apply best practices. That means the usual like version control, testing, and refactoring; but also good object oriented design, SRP, SOLID, ...

  • You're aware of the trade-offs involved in proper engineering and can make balanced business decisions, keeping in mind all the stakeholders of the project.

  • You’ve got opinions on code design and you can defend them, but you’re professional enough to not let those opinions get in the way of a consensus if necessary.

  • You have good knowledge and foresight of potential performance issues that might arise when working with large datasets.

Requirements

  • You have at least 4 years of experience working with Ruby, or 2 years of experience with Ruby and 4 years in other languages.

  • You grok Rails

  • Your work hours overlap with EU business hours (we require your local timezone to be within CET +/- 3h)

Good to have

  • Experience as a remote worker in a fully remote team

  • Experience with Javascript (ES6) and frontend frameworks

  • Experience in Fintech

  • Accounting knowledge

What we offer

  • Actual, proper work-life balance

  • Become a part of a fully remote development team with over 20 engineers

  • Free to choose your own schedule and work 100% remotely

  • A stimulating work environment with passionate, friendly and inclusive colleagues who value diversity

  • Team retreats twice a year

  • A €1000 yearly budget to spend on conferences, courses, workshops or other expenses that will improve your skills

*: Our ops team noted that this actually isn’t that hard to achieve if you’re indexing all the things, but it still sounds impressive, right?

  • Founded in 2007, Quimbee is one of the most widely used and respected study aids for law students. With a massive and growing library of case briefs, video lessons, definitions, and practice questions, Quimbee helps its members achieve academic success in law school. Quimbee can be accessed on desktop, tablet, and mobile devices.

    This position is 100% remote. All you need is an internet connection and a quiet place to work.

    Quimbee's tech team works on an agile process and has a great mix of seasoned web backend, frontend, and mobile developers. Quimbee's web and API platform is based on a monolithic Ruby on Rails application, and we make the effort to keep it updated to recent dependencies' versions. We're big believers on automated tests, and while we don't necessarily do test-first, CodeClimate rates both our maintenance and code coverage metrics with an A.

    This position is to work primarily on our web platform with an emphasis on our frontend code (views, HTML, CSS, JS) but also helping on backend work (controllers, models, serializers, query optimization, etc) whenever that's needed, so we're looking for someone with a passion for frontend but who's no stranger to backend code.

    Responsibilities

    • Design and write maintainable code following best practices, knowing that most of the time, good enough is better than perfect.
    • Help maintain and improve our frontend code, currently based on Slim, SCSS, Bootstrap, and plain JS with a mix of some jQuery. We're pushing to adopt RSJS on the JS front.
    • Help maintain and improve our backend code, including writing new features and adapting existing ones collaborating with our backend developers. We use Ruby on Rails.
    • Collaborate with teammates, the project manager, product, design, and QA teams during the whole SDLC, providing technical points of view, effort estimates, drafting or reviewing requirements, etc.
    • Take ownership of assigned projects and be responsible for communicating progress on a regular basis.
    • Participate in scheduled planning, review, and retrospective meetings on a regular basis (via videoconferencing technology)

    Task Examples

    Working with us, you could be asked to (solo or as part of a team):

    • Implement a new page from scratch from a new comp coming from our design team, leveraging existing HTML/CSS components when possible but implementing brand new ones when needed.
    • Take a raw, initial version of a new page or feature developed by our backend devs and "beautify" it by adapting its front-end code to reuse UI components and follow our style guide, in the context of our Ruby on Rails application. This requires a very good understanding of Rails' controllers and views conventions.
    • Review our existing JS code and refactor it to follow best practices.
    • Perform code reviews providing advice on how to improve code with a particular focus on Javascript.
    • Prepare and document reusable HTML/CSS/JS code components so that other developers can use them.
    • Setup a unit testing framework for our JS code and sponsor it among your teammates.
    • Work with other backend developers implementing a new API endpoint in Ruby serializing data in JSON for our mobile app.

    Requirements

    • B.S. computer science or related field
    • 5+ years of Javascript experience
    • 2+ years of Ruby on Rails experience
    • Excellent HTML & CSS experience (cross-browser compatibility, responsive media queries, flex, grid, etc.)
    • Advanced knowledge of the Javascript ecosystem (yarn, webpack, babel, etc)
    • Good understanding of SQL
    • Extensive Git (or similar) experience solving complex merging conflicts
    • Know how the web works under the hood: TCP, HTTP, DNS, IP, caches, etc.
    • Solid knowledge of OOP, software architecture, and design patterns
    • A deep understanding of the importance of building maintainable, efficient, clean code, while balancing that with the urgency of the business needs
    • Deep caring about uptime, performance, and reliability
    • The will to take responsibility for projects end-to-end from idea to completion
    • Fluency in English
    • Based in the U.S.

    Preferred Qualifications 

    • Experience with at least one programming language other than Ruby and JS
    • Familiarity with the concepts outlined in the Reasonable System for JavaScript Architecture
    • Experience working with Rails' server-generated JavaScript (SJR)
    • Experience working with JavaScript frameworks like Vue, React, Angular, etc.
    • Hosting apps in Heroku, monitoring and scaling them up/down
    • Implementing APIs for mobile apps
    • Implementing a SaaS application or with subscription-based businesses generally

    Benefits

    • Join a small team who loves what they do.
    • Work from home.
    • A competitive salary.
