About the job

This position is needed to help launch a new LLM powered application from prototype to production.

This new product will leverage the power of Twilio CustomerAI to create a new developer platform that allows builders to rapidly build personalized interactions for all customers.

Responsibilities

In this role, you’ll:

• Design clean interfaces between platform services and applications
• Develop fault tolerant systems to communicate with 3rd party APIs in a trusted and scalable manner.
• Collect information from 3rd party sources and expose that information directly to internal LLM systems.
• Create methods for interfacing with and monitoring the performance of non-deterministic, LLM powered applications.
• Collaborate with subject matter experts, fellow developers, and internal stakeholders to turn business goals into achievable technical roadmaps
• Drive operational excellence, maintaining robust uptime and enabling continuous delivery
• Mentor engineers on the team, leading projects, sharing domain knowledge, and positively influencing their careers

Qualifications 

Not all applicants will have skills that match a job description exactly. Twilio values diverse experiences in other industries, and we encourage everyone who meets the required qualifications to apply.

Required:

• Strong customer focus, taking the time to really understand their needs and ensure we are solving their problems.

• Experience maintaining and operating always-on cloud services
• Demonstrated commitment to seeking diverse viewpoints and acting with intention to create an inclusive team environment
• Excellent written and verbal communication skills.  Your knowledge is only as good as your ability to share it!  
• Schedule: Ability to work non-standard, on-call rotation weekend and holiday hours, shared evenly with all engineers on the team. We believe that we are responsible for the code we write and how it runs in production

Desired:

• Experience working with LLMs handling production workloads
