Senior Golang Full Stack Engineer

DNSai LLC is an independent technology company focused exclusively on building practical, high-performance tools for understanding and working with the Domain Name System (DNS). We are not an email security company. DNSai is a Cyber Security DNS Utility — a purpose-built set of utilities that make DNS data easier to access, interpret, and apply to real-world workflows across IT, security operations, research, and digital operations.

We are currently seeking a Senior Golang Full Stack Engineer to join our growing team. The ideal candidate will have extensive experience in Go/Golang, modern frontend technologies (JavaScript, React.js, Angular, Vue.js), and cloud technologies like AWS, Azure, Docker, and Kubernetes. Fluent verbal communication in English is the top priority for this position, as clear and effective communication is essential for collaboration across teams globally.

In this role, you will contribute to the development of both frontend and backend systems behind our DNS utilities — services that must stay fast, accurate, and reliable while processing large volumes of DNS data.

Responsibilities:

• Design, develop, and maintain scalable, secure applications and DNS utilities using Go/Golang, JavaScript, and modern frontend technologies.
• Build and maintain cloud-based infrastructure on AWS and Azure for high-throughput, low-latency DNS data processing.
• Develop and implement RESTful APIs that expose DNS lookup, enrichment, and analysis capabilities to internal and external consumers.
• Collaborate with product, research, and design teams to turn complex DNS data into clear, usable tooling, maintaining excellent communication throughout the process.
• Utilize Docker and Kubernetes to containerize applications, streamline deployment, and ensure smooth CI/CD pipelines.
• Troubleshoot, debug, and optimize applications for performance, scalability, and reliability at scale.
• Write efficient, maintainable, and testable code while following best practices in Go/Golang and JavaScript.
• Participate in code reviews to ensure adherence to coding standards, quality, and maintainability.
• Implement and manage CI/CD pipelines using AWS and Azure services for efficient and automated deployments.
• Ensure security and data protection across applications and services, in line with the expectations of a cyber security utility.
• Stay up-to-date with DNS standards, security trends, and platform technologies to continuously enhance development practices and tools.

Requirements:

• Proven experience as a Full Stack Developer with strong expertise in Go/Golang for backend services.
• Excellent verbal and written communication skills in English (fluent English is mandatory for this position).
• Strong knowledge and hands-on experience with AWS and Azure cloud services.
• Extensive experience with JavaScript and modern frontend frameworks (React.js, Angular, Vue.js).
• Expertise in containerization technologies such as Docker and Kubernetes.
• Proficiency with SQL and NoSQL databases (e.g., PostgreSQL, SQL Server, MongoDB).
• Familiarity with frontend technologies like HTML5, CSS, and pre-processors like SASS or LESS.
• Experience in building and consuming RESTful APIs for seamless system integration.
• Knowledge of version control systems like Git and collaborative development practices.
• Strong problem-solving skills with the ability to troubleshoot complex issues across the stack.
• Familiarity with agile methodologies and CI/CD processes.
• Excellent communication and collaboration skills to work effectively with cross-functional teams, often in different time zones.

Preferred Qualifications:

• Working knowledge of DNS concepts and protocols (record types, resolvers, zone data, DNSSEC, passive DNS), or a strong interest in learning them quickly.
• Experience with microservices architecture, serverless computing, and cloud-native applications.
• Familiarity with DevOps practices and infrastructure-as-code tools such as Terraform and CloudFormation.
• Experience with high-volume data pipelines or network/telemetry data.
• Strong understanding of security best practices and cloud-native security services.
• Experience with testing frameworks (unit, integration, and UI testing) to ensure code quality and reliability.

Why DNSai?

• Competitive salary and flexible payment methods.
• Deep, focused work in a single problem domain — DNS — rather than scattered consulting projects.
• Opportunities for growth and professional development.
• Flexible working hours and full remote work opportunities.
• Work in a collaborative, innovative, and inclusive environment that values creativity and cutting-edge technology.
• Be part of a data-driven culture with a global team, working in an open and communicative atmosphere.
