  • Improving the experience for agents using Twilio, through developing our own custom plugins
  • Improving monitoring and oversight of the platform to proactively catch issues
  • Establishing an ideal system architecture that allows us to scale effectively

Team mission

We aim to build the best customer service experience in the industry. Our staff use a system that effortlessly enhances their skills, while our customers enjoy a frictionless experience in achieving their goals.


The role

Underpinning all responsibilities is the expectation that you will be future-focused, evaluating our system, recommending changes, implementing changes and training others internally. Ultimately aiming to set up Lendable\xe2\x80\x99s Twilio services to scale in line with our future ambitions, helping the wider team to be as effective as possible.
  • Evaluate current interactive voice response (IVR) flows in Twilio Studio to suggest improvements and efficiencies.
  • Assess the architecture of our Twilio Flex setup (plugins, functions, repos), focusing on how we reduce the complexity of these systems.
  • Ensure we are following the latest standards in Twilio, including use of the latest software versions such as Twilio Flex 2.0 and assisting in upgrading our services to this.
  • Develop Twilio Flex plugins to meet the needs of our customer support teams.
  • Establish effective CI / CD environments to speed up the development process.
  • Advise on how we best manage Testing and Production environments.
  • Advise on usage of cutting edge Twilio features and services, going on to support or lead trials of the best technology on offer in this space.
  • Improve observability of the platform to proactively catch issues, such as through improved automated testing or proactive alerting.

What we\'re looking for

Must have
  • Proven experience (5-7 years) in software engineering roles, preferably leading on projects in a fast-paced and dynamic environment.

  • Understanding of future implications to scalability when designing new, or working with existing, complex systems. Be motivated to collaborate on these challenges with technical and non-technical stakeholders, in and outside of your immediate team.
  • Ability to identify the critical decisions to be made, assess them collaboratively with the relevant teams, and then communicate this effectively.
  • Ability and motivation to train others, share knowledge and establish best practice - identifying where we have gaps and resolving or engaging others in closing them.
  • Strong knowledge with React 16.x + Redux, using best practices to facilitate code scalability.
  • Experience working with different types of tests in Twilio Flex; e.g. unit, integration, end to end\xe2\x80\xa6
