We are looking for a Backend Software Engineer to join our development team in Amsterdam. Job duties will include working on Stream’s core API technology as well as designing and building high-performance software.
What you will be doing
Most of your day will be dedicated to software design, research, and coding. On typical projects, you will have a lot of freedom and you will be paired with another team member. Our team is made up of very experienced engineers, some with more than 10 years of experience. By working together you will learn from each other along the way. You will have an enormous impact on making our API service faster, more scalable and more flexible.
You will add new features to the service and find ways to make the existing ones perform orders of magnitude faster. Our customers have millions of users; they use Stream for mission critical features such as showing content and exposing core functionality of their application. Building stable and reliable software is not just an option: as a member of the development team, you will design and write state-of-the-art software, follow best practices, measure everything and be responsible for deployment to production. You will also spend part of your time talking to our customers and help them to use Stream in their app.
Our tech stack
At Stream we use a wide collection of technologies to offer highly optimized and available features to our customers. Over the years we have experimented with different programming languages, frameworks, databases, and libraries. Here is a short list of the technology that we currently use. Do not worry if you do not master them all or if you do not see your favorite tool or language, you will have the chance to be exposed to most and to convince us to expand the list:
What we have to offer you
Stream employees enjoy some of the best benefits in the industry:
Stream has a casual social culture, our team is diverse and we all have different backgrounds. Our Amsterdam team is very focused: you will see us heads down coding or drawing complex charts on whiteboards, until we pop up to have a chat or play merciless games of ping pong.
Our talented developers are highly technical and collaborative, which makes Stream a great place to learn and improve your skills. When it comes to software engineering our culture is oriented towards ownership and quality: our goal is to deliver stable software.

Head of Engineering
We are seeking a hands-on Head of Engineering for our well funded e-commerce fulfillment startup
At Bezos, our vision is to Deliver Happiness: For our team, for the end consumers, for our e-commerce sellers as well as our logistics partners.
Exciting times in e-commerce: E-commerce sales in Europe is projected to be £406 billion by 2023, expected to grow 8% per year between 2018-2023. The growth is driven by consumers that increasingly buy more online as well as the emergence of small and medium e-commerce sellers, which have grown at 18% and 28% per year, respectively between 2009-2017. There are 200,000 small and medium e-commerce sellers in the UK alone, selling their products through multiple channels, including marketplaces such as Amazon and eBay, their own websites, and on social media like Facebook and Instagram. Today, these small and medium sellers are ignored by the large incumbent logistics service providers and we are on a mission to change that.
Building a next generation Fulfillment-as-a-Service platform: With this explosive growth in e-commerce, the demand for e-commerce fulfilment and delivery is booming. Bezos is a next generation Fulfillment-as-a-Service (FaaS) platform, that allows small and medium e-commerce sellers to outsource their storage, fulfilment, delivery, and returns and focus on what is more important: growing their businesses. Bezos’ operational model is based on partnering with certified logistics suppliers that will execute the different services on our behalf. We believe there is a massive market opportunity to serve these currently unattended and fast growing small and medium e-commerce sellers. We believe that the e-commerce logistics landscape will give place to significant disruption opportunities, and we are planning on taking a leading role to achieve them.
Two founders with proven track records: The founding team consists of Diego Lijtmaer and Vernon Tjon-Soei-Len, who are two seasoned technology executives with experience in e-commerce, the gig economy and last mile delivery industry. Diego built the business development and logistics functions at Just Eat Plc (food delivery, FTSE 100), founded and ran a hospitality business Bacanal and worked in investment banking at UBS (LinkedIn profile here). Vernon was the Director of Amazon Flex UK (part of Amazon’s Last Mile Product & Technology team) and part of the Senior Leadership Team of Amazon Logistics UK, and prior to that worked at Zipcar, Bain & Company and JPMorgan (LinkedIn profile here).
We are looking for an exceptional technology leader: Someone that gets excited about the adventure of a startup and wants to build a world class billion dollar business. Someone that enjoys transforming industries, that enjoys changing the way businesses and consumers think about delivering and receiving e-commerce orders. Someone that is hands on, solves problems, and gets their hands dirty in the execution. Someone that has a demonstrated track record of building amazing technology and building and leading high performance tech teams.
