Will you join us on a journey to disrupt the trillion-dollar travel industry? We are looking for the best and brightest who share our passion for travellers, data and product.
FindHotel believes travel is the one thing that opens minds to new ideas, cultures, and ways of thinking. Our mission is to GET EVERY TRAVELLER THE BEST ACCOMMODATION DEAL, WORLDWIDE. From adventure travel and backpacking to honeymoons and family vacations, we genuinely care so that every traveller can make the best-informed accommodation choice at the absolute best conditions for every trip.
We are looking for an enthusiastic and motivated Senior Back-end Engineer to help build the best content and mapping product in the industry. You will be joining FindHotel’s Marketplace Platform Tribe, where you will be working with other squads across tribes and closely interact and actively collaborate with the software engineers, data analysts, data scientist, and PO in the team.
We are working with a modern stack consisting of Go, Python, AWS (ElastiCache, StepFunctions, EC2, S3), Snowflake, dedupe, and more. We process large amounts of content daily and integrate with many suppliers. Content and mapping products are an important part of FindHotel’s platform. They allow us to offer the best possible comparison and offers to every traveller, worldwide. Hence, anything that you will develop and ship to production will have immediate effect on our users and on our business performance. We work in a flexible, result-oriented and customer-centric team structure, focussed on shipping value in a collaborative fashion, with hopefully just the right amount of bureaucracy.
What you will actually be doing / responsibilities
What a day in the office might look like
In the morning, you and your fellow engineers have a refinement session with the PO to discuss the upcoming features on the roadmap. You carefully consider the impact of the new feature on the entire product and raise questions and make suggestions of what is the most pragmatic approach to balance the technical excellence with the time to market. You are part of a discussion that builds on top of each other suggestions, ideas and comments. Today you have chosen to come to the office and after lunch you play table tennis or pool or go for a walk with colleagues in the city centre. In the afternoon, you enter a deep work period and finish working on improving one of the provider’s mapping models. Once down with that work you jump on a zoom call with the rest of the team to discuss the challenges and next steps with the PoC the team is building in this sprint. Throughout the day you monitor the product operations using DataDog.

Our true purpose at Castor
Castor is one of the leading platforms for data collection in medical research. We believe standardizing and reusing datasets is key to overcoming the healthcare challenges of the future.
How we operate
Our main Electronic Data Capture (EDC) application runs on a proven stack consisting of Ubuntu, Nginx, PHP and MySQL. For our cloud installations, we orchestrate these setups by using Terraform combined with Ansible for the server configuration management.
Due to the nature of processing medical data, we have clients in different regions across the globe, often with specific regulatory constraints around where and how their research data is stored. To meet these customer demands we combine both traditional as well as cloud-based hosting solutions.
Most of our clients prefer to run in Azure, but we’re using Google Cloud Platform for things like Kubernetes hosting of greenfield projects, blob storage for scalable file upload storage and their Key Management System (KMS) to further secure our data.
For our metrics we’ve begun standardizing on Prometheus and we’re moving towards Loki for log aggregation. We use PagerDuty for alerting, communicate via Slack and host our code on Github.
Why we’re growing our team
With our recent expansion have come new challenges, both in how we organize ourselves and in how we manage and scale our infrastructure in the future.
To further these efforts we have formed a Platform team consisting of SRE and Software Engineering, which we are now looking to grow with the addition of an additional SRE.
Additionally, due to the sensitive nature of medical data, Castor is certified for both ISO/IEC 9001 (quality) and 27001 (Information security). In addition, we have to adhere to a number of other regulations, including Good Clinical Practice (GCP) guidelines.
Our goal is to unite these requirements with emerging SRE practices around infrastructure as code and other principles to create a well designed and documented system, while still allowing us to remain flexible to change.
How you will contribute
Our absolute commitment to patient data security and privacy informs our vendor selection with certified datacenter and cloud providers. To achieve real impact in medical research, Castor needs to operate security around the world.
Historically, our production platform has run on top of managed hosting services. This model doesn’t scale well for our global, international footprint, which is why we are currently expanding our in-house knowledge and transitioning to Infrastructure-as-a-Service providers.
As a Site Reliability Engineer, you’ll have the ability to shape our operations and continuously deliver a working product. Working very closely with the development teams, you’ll collaborate in supporting and structuring our efforts around automation, observability and security. With your help we plan to scale the Castor platform to the next level.
Some things we worked on recently
Whilst there are many operational challenges as we continue to grow and scale at Castor, our Platform team has made great improvements to a variety of our systems already. To give you some examples of what we achieved last month:
Your background
You have helped run web-facing services under production workloads and have experienced the challenges that come with maintaining and scaling these systems. Making and owning decisions about systems architecture together with your team is something you enjoy and feel comfortable with.
Qualities we’re looking for include:
How we say thank you
At Castor we truly live our core values, believing we can achieve anything with a healthy and happy team. With this in mind, we offer the following benefits:

At Careibu we are aiming to build the best social care community by students in the world. We are looking for capable, creative developers who want to help us accomplish that goal.
About Careibu Careibu is all about social care. Through our platform, we connect students to people for help at home. Our students work as babysitters, home cleaners and elderly assistants. Careibu’s Dutch community consists of 32.000+ students and 13.000+ clients. In Juni 2018, we officially launched in the German market (Berlin). Our mission is to bring all generations in society together and provide students a social side job.
Careibu was founded in student accommodation by two sisters, Lotte and Anne. They have grown the business from their student rooms to a team of 13 people which continues to rapidly grow. Our head office is located in Amsterdam.
Things we are working on We’re still a small company with an even smaller development team (CTO, product owner, backend developer and 2 mobile developers). This means you will need to wear many hats in the beginning but it also means there are many interesting challenges ahead that you can specialise in if you like. Broadly we are: – Migrating from legacy platform which has some interesting challenges – Improving and expanding our iOS & Android applications
Our technology stack We still maintain a stack built in Angular 1 (web UI), PHP (backend) and MySQL (data), however we are incrementally migrating to a new technology stack based on a Golang backend with native mobile apps (Swift for iOS and Java for Android).
Since we develop, test, deploy and operate our systems, we do work with other technologies that automate such processes, like GitLab, GitLab-CI, Docker and AWS’s ECS & RDS.
You should apply if – You want to be involved in building a product that has a social impact – You’ve worked in GoLang or you are a senior backend dev willing and able to learn quickly – You don’t mind exploring our legacy PHP system & rebuilding functionality on our new platform – You like to also be involved in improving the devops aspects of our stack – Experience with any of AWS EC2 & ECS, Docker or JavaScript/NodeJS is a big plus – You have a proactive attitude and are not afraid of failing – You (want to) live in the Netherlands (remote is not possible) – You have a EU passport (we don’t provide visa’s)
You want to apply or you have any questions? Email Anne (anne[at]careibu.com).
