About The Position

The company is building a privacy-first U.S. mobile carrier that provides secure, resilient cellular services to government agencies, enterprises, and consumers. Its platform is built on its own mobile core and SIM technology and is designed to minimize collection and retention of customer data. Following its Series C, the company is expanding its engineering organization and investing in internal platforms, tooling, and development infrastructure.

As the first dedicated Developer Experience engineer, you will shape how engineers across the organization build, test, and ship software. You will own the Developer Experience roadmap and build or improve internal platforms, developer tooling, workflows, CI/CD pipelines, local development environments, and Go development workflows. You will work with platform, product, infrastructure, network, and security teams, and help evaluate and implement AI-assisted development tools with appropriate guardrails and measurable outcomes. The role also includes establishing documentation, runbooks, guidelines, and engineering standards, and mentoring future Developer Experience hires. The position is full-time and hybrid, requiring at least three days per week in the New York, NY or Washington, DC office.

Requirements

• At least 4 years of professional software engineering experience.
• Strong engineering fundamentals and experience building tools, platforms, or infrastructure that improve other engineers' productivity.
• Experience with CI/CD pipelines and modern software development workflows.
• Experience improving developer tooling, local development environments, build systems, testing infrastructure, or deployment processes.
• Strong understanding of software engineering productivity and the challenges developers face when building and shipping software.
• Experience with Go or the ability to contribute meaningfully to Go development workflows.
• Experience collaborating with multiple engineering teams to identify technical bottlenecks and deliver improvements.
• Ability to independently identify problems, prioritize improvements, and execute solutions without a predefined roadmap.
• Strong technical judgment and ability to make decisions that benefit the engineering organization as a whole.
• Experience establishing engineering standards, documentation, and development processes.
• Strong communication skills and ability to influence engineers across teams.
• Ability to work from the New York or Washington, DC office at least three days per week.
• Must be eligible to work in the United States.
