Caseable Logo
Backend Engineer with Caseable
Berlin, Germany€50k - €70k
8 months ago

Job Description

Today, some Python using TDD. Tomorrow, clean code in Go and Elixir. Next week, maybe pair programming in Node.js? Feeling like writing a custom Nginx module in plain C? We have that too!

Sounds too cool to be true? Well, that’s exactly how we roll here in the Tech Team at caseable!

Don’t let yourself be fooled by a quick visit to the (fancy!) caseable.com website. What seems to be yet-another-boring-ecommerce-startup, is actually much more behind the scenes. We are a tech platform that allows other businesses from different sizes to achieve great customer experience, by horizontally increasing the range of products available with smart cross-selling solutions. You would have never guessed it, right?

Not to mention that we do quite a lot of image processing and provide solutions to our production facility (yes, we have a factory and manufacture physical products too!), with systems that will generate PDFs, control printers, organize logistics and much more.

This is a great opportunity to join a passionate team and make substantial impact on our business growth. You will experience supportive team members and the freedom to use your technical expertise and initiative to achieve shared goals. This position requires authentic curiosity and will to learn every day. We focus on quality and maintainability of what we do, in order to maximize the company goals in the long term, while executing urgent tasks with surgical precision when needed. We expect strong organizational skills, critical thinking and enthusiasm for achieving company and self-oriented goals.

What we offer

We offer you the opportunity to be part of an international team who is not afraid of learning on a everyday basis. You will have the possibility to experiment with new technologies and the freedom to choose your own equipment (high-end Linux or Mac laptops, with UHD external monitors) and software (your favorite IDE or simply Vim if you want).

Our environment is very supportive, where proposals for change and suggestions for improvements are encouraged. In addition, we offer flexible working hours and home office possibilities, an informal working environment with flat hierarchy, and competitive salaries. You will also enjoy our BBQ’s and events together with the caseable team.

As learning is a fundamental part of our style, you can expect to be going to congresses, conferences and meetups, doing workshops and reading books and other technical material in a regular basis.

Skills & Requirements

Your most important skill…

…is that you are open minded and eager to learn new technologies. You receive and give honest feedback and criticism, never taking it to the personal level, but as a fundamental part of achieving excellency.

We run on a microservices architecture, with containerized services in a very polyglot environment. We expect that you find this incredible, very exciting and maybe a bit scary, but in a good way. Python, Node.js, Elixir, Go, C and PHP are currently used, but we already have plans to introduce others, like Rust, Erlang, Lua and literally anything else that we believe will be a great tool for the task given.

Responsibilities

  • Code according to industry and team standards, adhering to good practices
  • Write maintainable, readable code with extensive test coverage, ideally applying TDD
  • Work with source control, dev/stage/prod release cycle and continuous integration
  • Get actively involved in the code and functional reviews of fellow developer’s work
  • Be able to spot logic and functional issues and effectively communicate feedback
  • Actively engage with team members to discuss backlog items, design issues, and best coding practices
  • Create technical documentation
  • Optimize application for maximum performance, scalability and maintainability
  • Working and developing RESTful APIs
  • Be in direct contact with infrastructure topics and understand the systems architecture
  • Work especially well with green field projects and sometimes with some legacy systems (luckily we already managed to kill most of these).

Skills & Experience

Mandatory:

  • Backend development, independent of the programming language, but including at least two of the following:

  • Python

  • Elixir

  • Go

  • Node.js

  • PHP

  • Erlang

  • C

  • Ruby

  • Passion for tested software: unit testing, automated tests, TDD

  • You can’t imagine how to code without Git

  • Linux, Bash & command line feels like home to you

  • Database knowledge (SQL and NoSQL)

  • Good knowledge of HTTP and RESTful APIs

  • Adherence to good practices and standards

  • Focus on quality, maintainability, readability, scalability and performance

  • Likes to work in an international, multicultural team

  • Enjoys pair programming, code reviews and knowledge sharing

  • Good English skills (written and verbal)

Good to have:

  • AWS
  • Continuous Integration
  • Ansible
  • Terraform
  • Microservices architecture
  • Docker
  • Monitoring tools (NewRelic, Kibana, Graylog, PagerDuty, etc)
  • Scrum, Kaban
  • Jira, Confluence

Typical day activities

  • Team sessions (with your fellow engineers and PO) to check data and brainstorm ways to improve several services performance and design scalable solutions
  • Solve open issues that affect component infrastructure reliability
  • Propose and discuss with fellow engineers efficient solutions for components and architectural design.

  • You have a sense of pragmatism, constantly finding the right balance between achieving technical excellence and delivering value to the end users
  • You are flexible, curious, and data-guided in helping us decide what to work on next

Job description
You’ll be working with a deeply technical engineering team who collectively bring a wealth of experience and broad technology skills. The calibre of the code we produce is what excites us each day and motivates us each. If you enjoy solving hard distributed system problems that are mostly platform agnostic and theoretical in nature, then you’ll love working at Ably. Our team is made up of a strong remote contingent, however our base is in London and growing. We are strong believers in face-to-face communication where possible. Whilst this is a remote working role, being able to practically travel to London occasionally is highly preferable and working on a similar time zone is a must.

Day to day you can expect to be working on:

  • The “core” realtime platform which is largely Node.js, and some shared services in Go. You may also be required to work on the various services and routing layers of the platform which are built in Go and Elixir (we would happy if you are comfortable in either Go or Elixir, both would be a big win). As an aside, we use Ruby for all infrastructure automation and orchestration and occasionally write lower-level native code where necessary (such as native modules for Node). We’re always revisiting the technologies we use and are always open to using new technologies where suitable.
  • Working within the realtime platform and solving distributed programming problems. Find out what it takes to be a distributed systems engineer.
  • Collaborating with the team to design, discuss and implement new features and services.
  • Diagnosing and fixing bugs in our platform using distributed tracing techniques.
  • Adding suitable test coverage to new features as well as existing functionality, conducting load tests using our frameworks, and generally helping to address platform stability and regression prevention.
  • Be responsible for the complete lifecycle of your features and code i.e. pull request, reviews, testing, deploy to staging and sandbox environments, then into production environments with ownership of any issues that arise. We are strong believers in all developers being involved in the system operations as well.
  • Contributing to open source projects that we support or use in our products. All of our client libraries are open source as well and may require your support at times.
  • Helping customers solve problems they are experiencing that may help us find bugs in the platform.
  • Support the wider team in regards to documentation and customer support.
  • Suggestions for new features or improvements to our protocol and API specifications.

Perks & Benefits

  • Salary range: £35k to £65k. Depends entirely on skills and experience.
  • Holidays: 25+ days excluding national holidays. Can be negotiated.
  • Benefit from a truly flexible working environment in which remote working and managing your own working time is the norm.
  • Work in an environment where code quality, technical challenges and delivery is what we all care about.
  • Skills development is intrinsic in the job. We’re largely working on unsolved problems each day, and such, there is plenty of scope to widen your knowledge and skillset.
  • Work with genuinely nice people who care.

Job Description

cancer.eliminate() // save lives

“The best minds of my generation are thinking about how to make people click ads … That sucks.”

-Jeff Hammerbacher

Cancer sucks. But, code is powerful, developers are brilliant, and people are resilient.

In the high cost world of oncology, trial and error treatment is still the norm despite enormous advances in genomic medicine. Patients are given one-size-fits-all treatments that lead to poor outcomes.

CancerIQ is building intelligent analytical technologies aimed to optimize cancer risk prediction, prevention, and treatment. We do this by providing care providers with workflow tools built upon informed decision engines and data-driven classification models. Our mission strives to engage and educate patients, and guide them through the complex, convoluted, and intimidating journey of cancer prevention.

How do you fit in?

CancerIQ Engineering is looking for curious minds that want to solve problems, write elegant code, and iterate quickly. We are a group of ambitious devs who love all things science, web, and technology.

As a CancerIQ Software Engineer, you will to take part in an agile engineering process. You will architect and implement backend and frontend solutions using Javascript, Ruby, Golang, Rust, Elixir, and other technologies best-suited for the goals of the CancerIQ platform. You’ll research, design, and propose architectural initiatives that incorporate domain-driven design into the microservices environment, employing sound data validation, provenance, and communication using technologies such as Kubernetes, GraphQL, and Kafka. You’ll be developing robust, performant services and user-friendly web clients that can enable clinicians to operate efficiently and gain new insights. Through intuitive visuals and interfaces, you will be creating modern and appealing applications across multiple platforms for patients of all types and demographics.

We want you to lead new efforts, promote best practices, and help the rest of the team grow in their engineering abilities through mentorship and teaching. We love pairing and so should you.

What are we looking for?

You should have several years of experience and completed many projects that have enabled you to develop strong opinions on code structure and modularization. With the rapid movement in the web landscape, you shouldn’t be afraid to dive into new technologies and learn from top to bottom. We use a mixture of technologies, and focus on those that help us get jobs done most efficiently. Knowledge of Javascript frameworks such as Angular, React, Backbone, and the like, should be something you can bring. You should have an expert-level understanding of Javascript (e.g. prototype-based inheritance, event delegation, closures, callbacks). You need thorough knowledge of the newer frameworks, and the progression of web technologies such as ES6/7, Typescript, etc.

You should have deep knowledge of the surrounding parts of the stack with the capability of designing RESTful APIs and backend services. As we scale to reach many patients and institutions, you’d make implementation decisions around scalability, performance, and web page optimization techniques. The desire to learn and help others are two core values that drive us as a development team. We believe that if you aren’t passionate about these values, then we’re not your best fit. You should be passionate about always learning and growing, as well as spreading new knowledge to just as passionate team members. As such, you’re a clear communicator and should be able to work with team members effectively.

What are the “Nice To Haves”?

Being able to navigate and contribute to the full stack will ultimately prove to be beneficial to the team. Knowledge of server-side technologies such as Ruby, Python, Java, Go, etc., would be excellent.

We employ a rapid, continuous deployment system, and as developers are responsible for seeing their features through deployment. Knowledge of DevOps and infrastructure tools (GitLab, Docker, Kubernetes, Istio, Kafka) will prove to be beneficial.

Anything Non-technical?

  • Self-motivated learning
  • Public artifacts and outreach such as blogs, open-source contributions, conference presentations
  • Strong communications skills such as empathy, listening, and conflict resolution
  • Passion
  • A good sense of humor
