FullStack Engineer with FuzzBuzz
San Francisco, USA$110k - $140k

Job Description

About Fuzzbuzz

We’re Fuzzbuzz and we’re building a fuzzing as a service platform that integrates into CI systems and the modern software testing workflow. Fuzzing is a type of automated testing that generates and runs thousands of inputs per second on your code to try and find bugs and vulnerabilities. It uses code coverage and other signals from your code to guide the tests it generates and runs. You can read more here.

Last year, we raised a $2.7M seed round from some of the best tech investors & founders, namely Y Combinator, Fuel Capital, Solomon Hykes (Docker founder), Flo Leibert (Mesosphere founder), Spencer Kimball (CockroachDB founder), Michael Stoppelman (Yelp ex-CTO).

About the Team

We’re currently a team of 5 people and prefer staying small - allowing us to iterate faster and get very comfortable working with each other (the 3 founders have been roommates since first year university). That means you’ll be 16% of the team - all of the work you do will be extremely critical and immediately impact users. We pride ourselves in being a very humble, but capable team - the 2 founding engineers each have 20+ years of engineering experience.

Since we are really small, we prefer having everyone working at the same location. We’re at 541 Jefferson Ave in Redwood City, CA - 10 mins from the Caltrain (everyone’s currently WFH because of COVID-19. We will resume working from the office when it is safe).

Why Fuzzbuzz?

1. Define the DevOps and security standards of tomorrow

Fuzzing is seeing more widespread usage than ever before, but there is still work to be done before it sees mass adoption. We’re uniquely positioned to bring fuzzing to the developer community and make software testing more effective than ever before.

2. Product-first culture with an emphasis on engineering

Working on a technical product means working with very technical people. We embrace technical challenges and take them head-on. We use tools/frameworks because they get the job done, not because they’re the current flavor of the month.

3. Early stage, funded startup

By joining Fuzzbuzz at this critical early stage, as one of our first team members, you’ll be shaping not only our product, but our company & engineering culture as well. We’re well funded, and pay in the top 10% of companies in SF at our stage.

What You’ll Be Doing

  • Design, architect and build the Fuzzbuzz platform (frontend & API)
  • Work with our designer to build a beautiful platform with a focus on simplicity
  • Work with fuzzing team to integrate fuzzing tooling into the platform
  • Work with founders to define product roadmap
  • Define internal engineering standards, tooling and processes
  • Work and iterate closely with users

What We’re Looking For

  • 2+ years experience as a full stack software engineer
  • Solid understanding of Typescript
  • Experience building complex SPAs in Angular or React (using TS)
  • Experience with or willingness to learn Go
  • Experience designing and building APIs
  • Experience working with AWS
  • Familiar with Linux
  • Strong fundamentals in distributed systems design and development
  • Obsession with users and providing real value to customers rather than working with “cool tech”
  • Ability to navigate & take ownership of complex problems from design through to final implementation

Benefits

  • Full health, dental & vision insurance
  • Caltrain & Parking covered
  • Unlimited, guilt-free PTO
  • Flexible hours
  • Ergonomic workstation (standing desk, Herman Miller chairs, custom monitor/laptop set up)

Stream Logo
Backend Developer with Stream
Amsterdam, The Netherlands€65k - €80k
4 months ago

Job Description

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.

The challenges

  • Distributed databases: we built our own data store for feeds and for chat
  • Real-time messaging
  • High performance: our API responses are in the 10ms range
  • High scalability: we use sharding, master-master, and master-slave to ensure scalability
  • High availability: our entire infrastructure is designed and operated to survive entire datacenter crashes
  • Multi-region: we deploy our service on 4 different continents

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:

  • Go, gRPC, RocksDB, Python
  • Postgresql, RabbitMQ
  • AWS, Puppet, CloudFormation
  • Grafana, Graphite, ELK, Jaeger
  • Redis, Memcached

What we have to offer you

Stream employees enjoy some of the best benefits in the industry:

  • A competitive salary
  • Company equity
  • A team of exceptional engineers
  • Healthy team lunches
  • Plenty of snacks and fancy coffee/teas
  • An office in the heart of Amsterdam
  • The possibility to visit our office in Boulder, CO
  • The opportunity and support to attend and/or present to industry-related conferences and meetups
  • The chance to work on OSS projects

Our culture

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.

If you are interested in becoming a part of what we do, apply now!
