Job description

About us

One team. Global challenges. Infinite opportunities. At Viasat, we’re on a mission to deliver connections with the capacity to change the world. For more than 35 years, Viasat has helped shape how consumers, businesses, governments and militaries around the globe communicate. We’re looking for people who think big, act fearlessly, and create an inclusive environment that drives positive impact to join our team.

What you’ll do

Our team builds data-driven products that directly drive Viasat's revenue growth by transforming how our sales teams operate. We create innovative data and software tools that sales teams use to close more deals and identify new opportunities.

As a Software Engineer, you’ll develop and help shape the technical direction of our platform ecosystem: web portals, automated document generation systems, and cloud applications that process billions of records. You’ll contribute to technical decisions — from selecting frameworks to designing integrations between BigQuery data pipelines, Salesforce, and enterprise authentication systems. Working in a multi-language, hybrid-cloud setting utilising Python, TypeScript, AWS, GCP and more, you’ll build high-performance solutions while contributing innovative ideas for future capabilities. The goal is to provide clear user interfaces for a variety of internal and external stakeholders, giving them greater insight into their business and driving efficient workflows.

Your work directly influences how hundreds of sales professionals across global business units identify prospects, prioritise opportunities, and close deals. You’ll see your contributions translate into measurable outcomes: new contracts won, time saved in sales cycles, and millions in incremental revenue. The tools you build will be used daily by teams in the field.

You’ll work with Analytics Engineers in your team who build the data pipelines powering your applications, sales teams across business units who provide direct feedback, product and commercial teams who understand customer needs, as well as data engineers and IT teams who help scale solutions. This cross-functional exposure gives you unique perspective on both technology and business context. You’ll help scale successful, well-loved tools from MVP stage to enterprise-grade platforms serving new markets, working in a small, collaborative team with startup pace but enterprise resources and mandate.

The day-to-day

You’ll design and implement new products and tools across the full stack, from APIs and service architectures to frontend interfaces. Daily work involves reviewing technical designs with Analytics Engineers, contributing to system integration and design decisions, and writing code in Python and TypeScript from infrastructure through to user interface.

A typical day includes building proof-of-concepts for new tools and products, evaluating their fit for the platform architecture, and presenting technical recommendations to the team. You’ll investigate and resolve production bugs, optimise web portal performance and rendering efficiency, debug Lambda functions, and refactor components to improve reliability and maintainability. You’ll design efficient data patterns in the cloud to handle high-volume datasets and ensure applications remain responsive under load.

You’ll work alongside team members to define technical requirements for new features, propose implementation approaches, and estimate development effort. This includes supporting integration patterns between systems, implementing authentication and authorisation for enterprise portals, specifying API contracts, and selecting scalable technologies that can grow with the platform. You’ll also spend time on infrastructure work: deploying services via Terraform, configuring CI/CD pipelines, architecting document generation systems, and ensuring applications meet performance and security requirements for enterprise deployment.

What you’ll need

• Strong Python development experience building production applications
• Solid AWS experience, including services such as Lambda, ECS/Fargate, S3, and API Gateway
• Experience deploying and managing containerised applications using Docker
• Good SQL skills and experience working with data warehouses
• Hands-on experience with Infrastructure as Code tools, particularly Terraform
• Proficiency with Git and modern CI/CD workflows
• Experience contributing to the design and implementation of multi-component software systems

What will help you on the job

• Experience with modern web development frameworks, particularly Next.js, React, and TypeScript
• Familiarity with Google Cloud Platform services, especially BigQuery
• Knowledge of enterprise authentication patterns including SSO, SAML, OAuth, and RBAC
• Experience processing and optimising applications that work with high-volume datasets at scale
• Background in B2B SaaS, sales enablement tools, or CRM platforms
• Experience designing and automating ETL pipelines at scale
• Experience supporting the scaling of MVPs into enterprise-grade platforms
• Experience working in Agile environments using tools like JIRA
• Comfort working across the full stack from infrastructure to frontend
• Understanding of how technical decisions impact business outcomes and user adoption
• Experience with automated document generation or data visualisation libraries
