 As a JavaScript Engineer, you will be required to work on various JavaScript libraries that are served on our customers’ websites thereby impacting millions of users. These libraries are the core of all the features of VWO. 

We love vanilla JavaScript and work with cutting-edge technologies like TypeScript, Rollup.js, Cypress, ESLint.

We are obsessed with Web Performance. See some of the improvements that we did  https://engineering.wingify.com/posts/performance-improvements-in-vwo-smart-code/

Job Responsibilities:

  • Development of Core JavaScript libraries.
  • Writing reusable code or modules that can be used across all the JavaScript libraries.
  • Talking about your work - we love open source software, we heavily use them, and talking about how we use them is the least we can do to help the community. See our engineering blog and our GitHub page

Expectations from you to succeed in this role 

We have identified some must-have expectations from this role. As a senior software engineer, you will be meeting expectations (which is a good indicator of your performance) if you qualify for all must-have expectations for most sprints. Differentiators are not explicit expectations but would exceed expectations from this role and would likely put you as a great performer. 

  • Timely delivery (Must Have)
    1. The most important expectation from any individual. This expectation is independent of the experience level.
    2. Can be defined as the delivery of the tasks within the agreed time frame along with agreed quality standards.
    3. Can be broadly categorized into the following streams:
      1. Feature Requests - To deliver new feature requests as per the agreed scope at the start of the sprint. Definition of Done (DOD) still needs to mature.
      2. Customer Bugs - To be delivered in a linked sprint. In certain cases, some critical bugs can take the highest priority.
      3. Tech Debt - Timely delivery of tech debt tasks with scope finalized at the start of the sprint. Again, quality standards must be followed.
  • Ownership & Accountability (Must Have)
    1. This expectation will vary according to the experience level as well as the role.
    2. Junior team members are expected to deliver their tasks with help from others.
    3. Senior team members are expected to help junior team members as well as deliver their own tasks. They are also expected to take ownership of the end-to-end delivery of projects including stakeholders management.
    4. Some individuals performing some specific roles like Scrum Masters are expected to perform role-specific duties. 
  • Quality delivery (Must Have)
    1. Deliver tasks adhering to the existing quality standards. 
    2. Quality standards may vary from service to service. Everyone should agree on the benchmark and should follow it strictly
    3. Dev Testing is very crucial before handing over anything for QA. Any obvious misses in requirements or bugs should be considered as bad quality delivery.
    4. Repeated misses in pull requests will be considered bad quality
  • Teamwork (Must Have)
    1. Coordination among team members during sprints.
    2. How well team members can resolve blockers without external help.
    3. Effective communication between team members. If things are getting delayed because of poor communication, it’s a bad sign.
    4. For senior members, coordination with other teams i.e. Product, Design, other stakeholders is also important
  • Self-initiation (Differentiator)
    1. Ideas to improve current architecture and to take the ideas to completion
    2. If something crucial is being reported, how fast someone is resolving it
    3. How are people reacting to their free time? Are they always trying to utilize it by working on things from backlog or tech debt items?

Engineering Performance Process

We follow a continuous performance cycle inline with our sprint cycles. A 360 review based on agile principles is rolled out after every two sprints that covers feedback on and from scrum masters and peers. 

A formal review is kicked off twice a year and the feedback from sprint cycles is accommodated for a holistic evaluation. 

Its not all work! 

Between work and learning, we don’t forget to have fun!

Regular hackathons, Show and Tell sessions within the team, a book club, beach trips (pre-Covid) keep us busy.
