Backend-Leaning Full Stack Software Engineer

About the Company We are partnering with an early-stage, venture-backed technology company building mission-critical software for spectrum access, licensing, data management, and technical analysis across government, defense, satellite, and other highly regulated environments. The company is replacing slow, manual workflows with modern software that helps organizations manage complex operational data, navigate regulatory processes, and make faster technical decisions. The team is small, engineering-led, and already supporting real customers in production. About the Role We are looking for a backend-leaning Full Stack Software Engineer who wants meaningful ownership and the opportunity to build major parts of a platform from the ground up. You will work across backend services, APIs, data pipelines, cloud infrastructure, and customer-facing product surfaces. This is a hands-on individual contributor role for an engineer who enjoys solving ambiguous problems, making architectural decisions, and working directly with customers and company leadership. The ideal balance is approximately 70% backend and 30% frontend. What You’ll Do Design, build, and operate production backend services and APIs

Own features and systems from initial customer discovery through deployment

Build scalable data-processing and event-driven workflows

Develop secure authentication, authorization, and role-based access-control systems

Work with large, complex datasets and mission-critical operational workflows

Build customer-facing product experiences using modern frontend technologies

Deploy and operate services in AWS-based cloud environments

Establish reliable testing, observability, CI/CD, and production-support practices

Evaluate architectural tradeoffs and challenge assumptions, including AI-generated technical recommendations

Collaborate directly with customers, engineers, and company leadership What We’re Looking For 3–6 years of professional full-stack or backend software engineering experience

Recent experience owning and shipping meaningful production systems

Strong backend development experience, ideally using Python

Experience designing REST, GraphQL, or equivalent production APIs

Hands-on experience with AWS and cloud infrastructure

Experience with event-driven or distributed architectures using Kafka, SQS, RabbitMQ, pub/sub systems, or similar technologies

Experience with relational databases, data modeling, and production data workflows

Ability to contribute across frontend technologies such as React and TypeScript

Experience building authentication, authorization, IAM, or RBAC functionality

Strong technical judgment and the ability to explain architectural decisions and tradeoffs

Exceptional written and verbal communication skills

Comfortable remaining a hands-on individual contributor in a fast-moving startup environment Strong Plus Experience at a Seed–Series C startup or as an early/founding engineer

Experience building a product or system from zero to production

AWS GovCloud experience

Current or previous U.S. security clearance

Experience supporting government, defense, aerospace, satellite, or regulated-industry customers

Experience with Docker, Kubernetes, Terraform, or similar infrastructure tooling

Familiarity with AI coding tools and the ability to critically evaluate their output

Customer-facing engineering, solutions engineering, or forward-deployed experience You may be a strong fit if you: Prefer ownership over narrowly scoped tickets

Enjoy turning incomplete customer needs into production software

Can move quickly without sacrificing technical judgment

Are comfortable working across backend, infrastructure, data, and frontend systems

Ask why systems work instead of relying entirely on existing playbooks

Want to stay close to the code and are not looking to move immediately into management

Communicate clearly, collaborate without ego, and enjoy working with customers

Work Environment This is a highly collaborative, in-person engineering environment in New York City. Team members work onsite five days per week and have direct influence over the product, architecture, and customer experience. Relocation assistance may be available for qualified candidates.
