Staff /Lead Software Engineer - Back End

Upwork is the world's top freelancing website. Each year over $1 billion of work happens through Upwork, helping businesses get more done and freelancers work anytime, anywhere on projects they love. At Upwork you'll help build on this momentum and create economic and social value on a global scale, providing a trusted online workplace for professionals to connect, collaborate and succeed.

Are you an experienced Software Engineer who is up to the challenge of building cutting edge, large scale web services that power a platform used by millions of freelancers and their clients around the world every day? Do you relish solving seemingly impossible problems? Do you love identifying potential scalability issues before anyone else, on a product that is growing quickly, and coming up with creative solutions to them? Do you spend time thinking about the CAP theorem, caching, and elegant API design? If so, we'd love to hear from you.

Upwork is looking for a passionate, proactive, creative, rock star engineer and technical leader to design and develop innovative solutions that help improve the platform for clients and freelancers alike. As a global company, we have some interesting challenges from an engineering perspective. Improving the performance and resilience of our products over high-latency / low-bandwidth network connections and implementing self-healing protocols to handle failure scenarios are just a couple of the areas where we have significant room for improvement.

Your Responsibilities:

  • Architect, develop, and deliver scalable microservices that are core to the business, using the latest open source tools and technologies.
  • Establish architectural principles, select design patterns, and mentor junior team members.
  • Be at the forefront of a company-wide effort to transition away from a monolithic legacy application stack to a modern, distributed architecture based on microservices.
  • Drive a high standard of excellence for web service scalability and availability.
  • Produce high-quality software that is unit tested, code reviewed and checked in regularly for continuous integration and deployment.
What it takes to catch our eye:
  • BS or advanced degree in Computer Science or related field.
  • 6+ years of experience designing and developing scalable and highly available REST microservices using J2EE.
  • Excellent written and verbal communication skills. Our teams are widely distributed, and you will be required to communicate with technical and non-technical audiences across different cultures.

How to really knock our socks off:
  • Proven ability to work in a fast-paced, iterative environment and lead the parallel development and delivery of multiple product features while paying off technical debt.
  • Experience in profiling and tuning Java applications for maximum performance.
  • Strong focus on the customer and the business, coupled with a burning desire to learn, respond to feedback and grow. We're looking for people who thrive on learning new technologies and don't believe in one-size-fits-all solutions.
