ABOUT US

We are a leading software development agency delivering high-quality UX/UI design, e-commerce solutions, and web and mobile applications across various industries, including e-commerce, education, and Fintech. Our mission is to help businesses scale with innovative design and technology.

ROLE OVERVIEW

We are seeking a talented US-based Software Engineer to join our engineering team and lead the design, development, and scaling of robust backend services and web applications. In this role, you will take technical ownership of end-to-end software architecture, build high-performance APIs, optimize database operations, and integrate modern cloud services to power complex client applications.

Please note: Due to project requirements, we need only US-based applicants. Other nationalities will be rejected.

RESPONSIBILITIES

Design, develop, test, and deploy scalable backend services, microservices, and web applications.

Architect and maintain RESTful and GraphQL APIs, webhooks, and data pipelines.

Optimize application performance, system reliability, data structures, and database query efficiency.

Collaborate with cross-functional teams (product management, UI/UX design, and front-end engineering) to turn product requirements into technical implementations.

Conduct code reviews, establish engineering best practices, and maintain technical documentation.

Ensure high standards of application security, data protection, and system monitoring.

REQUIRED SKILLS AND EXPERIENCE

Must be based in the United States (US-based applicants only; other nationalities will be rejected).

Proven software engineering experience building and deploying production-grade applications.

Strong expertise in modern backend languages and frameworks (e.g., Node.js, Python, Go, or Java).

Solid understanding of database design, management, and query optimization (SQL and NoSQL like PostgreSQL, MySQL, Redis, MongoDB).

Experience with version control systems (Git), CI/CD workflows, and unit/integration testing frameworks.

Strong grasp of core computer science fundamentals (data structures, algorithms, object-oriented design, system design).

Excellent written and spoken communication skills in English.

NICE TO HAVE

Experience with cloud platforms (AWS, GCP, or Azure) and containerization tools (Docker, Kubernetes).

Familiarity with front-end frameworks (React, Next.js, or Vue.js).

Experience with serverless architectures, event-driven messaging systems (Kafka, RabbitMQ), or AI/LLM API integrations.

Background in system security, OWASP guidelines, and compliance standards.

WHY YOU’LL LOVE WORKING WITH US

Work at the intersection of AI, product design, and engineering.

Be part of a remote-first team passionate about innovation.

Opportunities for skill growth, mentorship, and meaningful impact.

Enjoy a culture that values learning, ownership, and excellence.

HOW TO APPLY

Please include in your proposal:

An attached copy of your Resume.

Links to past projects, GitHub repositories, or technical portfolio.

A brief description of a complex software engineering problem you solved recently and your technical approach.

Confirmation that you are located in the United States.
