Internal Applications Engineer - Network Evolution at Bandwidth

Company: Bandwidth
Location: Raleigh, NC
Employment type: full-time
Posted: 2026-08-19

Who We Are:

At Bandwidth, we shape how the world connects. We're the global communications software company and Tier 1 network operator with global reach. The voice, messaging, and emergency services infrastructure behind the brands and apps you use every day.

Because we own the network we build on, the problems you'll solve here are bigger, more complex, and more impactful. And as communications shifts to AI, we're the infrastructure layer making it possible.

We call ourselves BANDmates because building something this big takes collaboration, different perspectives, and the freedom to bring your authentic self to the table.

We're experts who speak like humans. Ready to build what's next? #JoinTheBand

What We Are Looking For:

Bandwidth's Network Strategy team manages the systems behind voice network costing, routing, pricing, and carrier relations. We're looking for an Internal Applications Engineer who loves building things that make people's work smarter — someone who can craft the internal tools, automations, and AI-powered solutions that keep our network running smoothly and efficiently.

You'll work across the full stack — Python scripts, API integrations, React apps, and Snowflake pipelines — and you'll use AI development tools as a core part of how you work. If you get excited about solving real operational problems with smart engineering, this is the role for you.

What You'll Do:

Automate what slows us down. Dig into voice costing, routing, pricing, and carrier management workflows to find where work could be optimized — then build smart solutions using generative AI, workflow orchestration, and conventional software to fix it.
Build internal tools teams actually love. Develop and maintain user-facing applications, deployed on the team's AWS and Snowflake infrastructure. We care a lot about reliability and clean user experiences.
Configure and maintain integrations between Bandwidth's operational platforms — ServiceNow, Drivetrain, TEOCO, Snowflake, and others — using Software to identify, orchestrate across systems and streamline workflows with best ROI.
Support data pipelines. Help build and maintain workflows that land data from operational systems into Snowflake so downstream teams always have what they need.
Put AI to work. Use LLM APIs (Anthropic, OpenAI, and others) to build solutions that surface insights, automate responses, and sharpen decision-making. Lean on AI-assisted tools like Claude Code as a daily part of your workflow.
Write scripts that scale. Build Python and JavaScript automations to reduce repetitive work and extend capabilities across the team's stack.
Test, ship, and iterate. Write tests alongside your code (not as an afterthought), collect feedback from real users, and keep making things better.
Document as you go. Leave things better than you found them — clear documentation of what you built, why, and how to operate it.
Collaborate with people who care. Work with teammates across Network Strategy, carrier relations, pricing, cost management and finance to understand what they need, share what you're building, and help new tools land well.

What You Need:

Education: Bachelor's degree in Computer Science, Data Sciences, Information Technology, or a related field — or equivalent hands-on experience.

Experience

Python and/or JavaScript in a production or project context
REST API integration, in any language or platform
Familiarity with workflow automation platforms
Experience with SQL and Snowflake
Regular use of AI development tools (Claude Code, Cursor, Copilot, or similar)
Experience with automated testing frameworks like Pytest or Vitest — you write tests alongside code, not after the fact
Exposure to developing in cloud platforms like AWS

Technical Skills

Software fundamentals: functions, data structures, control flow, and writing code other people can read and maintain
Ability to read API docs, parse error messages, and diagnose issues on your own
Understanding of authentication patterns (API keys, OAuth, tokens) and when to use them
Familiarity with JSON, webhooks, and event-driven patterns
Basic understanding of containerization and cloud deployment
Ability to build and maintain databases, create schemas, and generate SQL’s
Understanding of data security and privacy best practices

Soft Skills

You communicate clearly — whether you're working with an engineer or a business stakeholder
You adapt well when priorities shift (and they will)
You follow a problem until you truly understand it, not just until it stops throwing errors
You take quality seriously: documentation, testing, and clean code matter to you

Bonus Points

Basic knowledge of Voice Telecom Networks
You can write working Python, Java and debug problems independently
You use Git as a habit — commit often, review incrementally
You can explain what you built, the tradeoffs you made, and how to run it in production
You're genuinely curious and persistent — you like understanding why, not just what
