With a robust multi year roadmap IDEXX has invested heavily in Veterinary Software, and we’re seeking a skilled Senior Front End Engineer to join our Vello squad. Your focus will be delivering high quality solutions that overcome complex challenges related to our portfolio of cloud platforms and applications. Come help us push the boundaries of what veterinary software can do.

But what is Vello? Vello gives everything a vet needs to connect with their clients—all in one place. It streamlines the ways they engage with pet owners with a single experience built for IDEXX PIMS. With software-supported engagement across the life stages of a pet, pet owners become informed partners in care—supporting better health outcomes. Vello is built on AWS with a cloud-native approach. We use Lambda for serverless computing, TypeScript for development, and combines DynamoDB with Postgres RDS for data management. ECS containers handle deployment, scalability & performance.

Within IDEXX we are a part of the IDEXX Veterinary Software portfolio. With a focus on software solutions, we are dedicated to enhancing the health and well-being of pets, people, and livestock around the world. Through the power of the cloud, our solutions simplify the flow of information across any practice and link vets to what they need when they need it. Patient data. Client communications. Business insights. All at their fingertips.

Our journey is solving veterinary practices’ most pressing needs by focusing on innovation to drive meaningful improvements in animal health.
