Senior Software Developer

Description:

Call Box exists to grow people. We believe that everyone wants to become a better version of themselves, and we work hard to provide a software and a culture that maximizes that growth mindset. We hire smart and ambitious doers and set them loose in an exciting and complex technology business where they will build, sell, and deploy Artificial Intelligence solutions in a dynamic business environment. Our solutions attack one of the biggest business problems in existence today: the phone.

Senior Developers are highly-motivated, passionate people who push boundaries as they explore new ideas. Senior Developers leverage their technical expertise to continually create and deliver products that delight our users, mentor our more junior team members and elevate the team through cultural leadership. We are looking for fearless, self-motivated people who are seeking an opportunity to steer product direction, create and manage their own projects, and constantly grow in their abilities.

We process 30 million calls a month across 4,000+ customers. We're modernizing a 20-year-old platform into event-driven microservices using Go, NATS, Nest.js, and modern patterns. We need developers who ship quality code at pace.

Please note: Applicants must be authorized to work for ANY employer in the U.S. We are unable to sponsor or take over sponsorship of an employment Visa at this time.

What You'll Do

• Build and maintain microservices handling real-time telecommunications and reporting workloads
• Work across the stack: APIs, messaging systems, data pipelines, and integrations
• Own features from design through production deployment
• Contribute to architectural decisions as we decompose a legacy monolith
• Write code that your teammates don't have to fix later

Requirements:

What We're Looking For

• 5+ years professional development experience
• Strong Linux experience; knowledge of POSIX and other system interfaces
• Proficiency in at least one compiled language (C, C++, Go, Rust, etc) and one interpreted language (TypeScript, Python, Perl, etc)
• Solid understanding of relational databases and SQL (we run heavy PostgreSQL and SQL Server workloads)
• Experience with message queues, event-driven architecture, or distributed systems
• Track record of shipping features independently without constant direction
• Experience with Kubernetes, Helm, and AWS

The Kind of Person Who Thrives Here

• You have opinions about how things should be built and you voice them
• You use AI tools to accelerate your work, and you understand what they produce well enough to own the output
• You're restless at companies where nothing improves
• You finish things; your Git history reflects consistent output, not sporadic bursts
• You've grown your skills noticeably year over year and can articulate how

We Don't Care About

• Degrees or certifications
• Whether you've worked at a name-brand company
• Years of experience beyond demonstrable competence

What We're Building For
We're not a waterfall shop. Requirements here aren't handed down in 50-page specs. You'll often start with a problem and figure out the right solution. The developers who do well here are the ones who naturally think about what would make the product better, pitch those ideas, and build them. If you're someone who sees an opportunity and just makes it happen rather than waiting for permission, you'll fit right in. If you need every edge case defined before you write a line of code, this probably isn't the right environment.
