About Upfluence
Upfluence helps brands tell their story with powerful influencer & content marketing technology. Upfluence’s software allows brands and agencies to identify and contact millions of social influencers and bloggers at scale to execute comprehensive influencer marketing campaigns, as well as provide detailed reporting metrics. Since the launch of our SaaS software in January 2017, the company has yielded a monthly double-digit growth rate, and we are therefore seeking further expansion for our team and offices. Our rapidly growing global team is currently distributed between our offices in NYC, Los Angeles, Switzerland, and Lyon.
We are now looking for a talented and passionate Back-end Engineer who, together with the product team, will take part in creating and constantly improving the online platform.
What we do
Our platform aggregates, keeps up to date and serves the content of 5M of influencers across all trending social networks of the internet. This raises a certain amount of engineering challenges related to data, scalability and performance. At the scale we’re at, the naïve solution often isn’t enough.
Our backend stack is focused around Golang / Ruby as programming languages, PostgreSQL, Apache Cassandra as database systems, Elasticsearch as a search engine, RabbitMQ as message broker. Also, we use Apache Thrift for RPC and Prometheus for monitoring to name a few.
We’re firm believers of micro service architecture and domain driven design, making our codebase highly flexible and reusable. Some parts of our production have actually been running for more than 5 years!
We’re DevOps minded. Our backend engineers ship to production multiple times a day and are responsible for their production. We’re always working towards reducing the maintenance toil by automating as much as possible our processes using tools like Github actions or our own in-house frontend deployer.
We’re running around 50 applications in production, making it around 1600 containers live, across 90 servers. Not to mention that we’ve been running containers in production for more than 7 years. We’re currently in the works of moving our production workload to Kubernetes.
We’re product-centric: we’re not writing code for the sake of it, but to provide the best service to our customers.
We strongly believe that collective intelligence is the very root of success for an engineering organization. Each and everyone has a word to say regarding the technical implementation of a feature. That’s why we rely on tools like proposals and RFCs to encourage this culture, as the best companies in the field do.
We love open source and contribute to it by opening our own libraries to share them with as many people as possible.
Responsibilities
Writing highly reliable, maintainable and tested code that makes the correct assumptions based on the context. You know that in our field, everything is a matter of tradeoffs.
Getting involved in the feature lifecycle, from its inception, through its technical design and implementation, to its maintenance in production 3 months / years after releasing it ;-).
Work in collaboration with the team, get involved in mentoring juniors, reviewing PRs and writing RFCs. Being at ease with written communication is a must.
Work hand in hand with Customer Success and Support teams, to make sure our customers have the best experience using our product.
Who we are looking for
You’re eager to discover how our product works and you’re keen to learn and master its technologies. We’re looking for enthusiastic people and great learners who go beyond the tools, not technical experts. Of course, if you already have experience with our stack that’s a plus, but definitely not a requirement.
You like to work in a team and to take on challenges, and you are fluent or comfortable working in English. Our team is based mostly in France, but speaking French is not a requirement.
You’re reliable: You keep your word when you can, communicate early on and come up with solutions when it looks like [we || you] are running into a wall.
You’re not afraid to ask questions and raise issues.
You’re a team player.
You care about the product and strive to make something useful.
What we can offer you
Your spot with the team in one of our awesome Lyon or LA offices, or even remote, either way is fine with us. You’ll be answering issues on Github and making bad jokes on Discord anyway!
An entrepreneurial and dynamic startup environment with room for growth;
A mixed and international team (10+ nationalities);
An empowering and autonomous position in an entrepreneurial environment;
Upfluence is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.
Interview Process
The interview process would go through 4 steps as followed:
After sending your resume, the team is in charge of reviewing and selecting candidates: if you are selected, you'll have the chance to discuss for a 1st interview with 2 members of the team;
If the interview goes well, the team will send a little technical test your way for completion;
Upon the test being sent back, the team is charge of reviewing it and we program a second interview to debrief it with you;
If the test and debrief interview were successful, the last stage consists in an interview with at least one of the founders of the company, to get to know more about you and what you want to accomplish with us.
