Software Engineer (Backend) – Kotlin & React
About Us
We are a high-agency startup building elegant technological solutions to real-world problems.
Our mission is to build world-class systems from scratch that are lean, fast, and intelligent. We are currently operating in stealth mode, developing deeply technical products involving Kotlin, React, Azure, AWS, GCP, Google Maps integrations, and algorithmically intensive backends.
We are building a team of builders — not ticket takers. If you want to design systems, make real decisions, and own your work end-to-end, this is the place for you.
Role Overview
As a Software Engineer, you will take full ownership of building and scaling critical product systems. You will work directly with the founding team to transform complex real-world problems into scalable technical solutions.
This role is ideal for engineers who enjoy thinking deeply about systems, writing clean code, and building products from 0 → 1.
Key Responsibilities
System Development & Architecture
- Design, develop, and maintain scalable backend services, primarily using Kotlin or JVM-based languages (Java/Scala).
- Architect systems that are robust, high-performance, and production-ready.
- Apply strong data structures, algorithms, and system design principles to solve complex engineering challenges.
Full Stack Development
- Build fast, maintainable front-end applications using React.
- Ensure seamless integration between frontend systems and backend services.
Cloud Infrastructure
- Design and manage cloud architecture using AWS, Azure, and/or Google Cloud Platform (GCP).
- Implement scalable deployment pipelines, monitoring, and infrastructure optimization.
Product & Technical Collaboration
- Work closely with founders and product stakeholders to translate business problems into technical solutions.
- Contribute actively to product and engineering roadmap decisions.
Performance Optimization
- Continuously improve system performance, scalability, and reliability.
- Implement efficient algorithms and system optimizations to gain a technical advantage.
Engineering Excellence
- Write clean, well-tested, and maintainable code.
- Maintain strong engineering standards across the codebase.
Required Skills & Qualifications
We value capability and ownership over years of experience. Whether you have 10 years of experience or none, what matters is your ability to build and solve hard problems.
Core Requirements
- Strong computer science fundamentals (Data Structures, Algorithms, System Design).
- Experience with Kotlin or JVM languages such as Java or Scala.
- Experience building modern React applications.
- Hands-on experience with cloud platforms (AWS / Azure / GCP).
- Experience designing and deploying scalable distributed systems.
- Strong problem-solving and analytical thinking.
Preferred / Bonus Skills
- Experience with Google Maps APIs or geospatial integrations.
- Prior startup experience.
- Contributions to open-source projects.
- Personal side projects demonstrating strong engineering ability.
Ideal Candidate
You will thrive in this role if you:
- Take ownership of problems, not just tasks.
- Are comfortable working in high-ambiguity environments.
- Have a builder mindset and enjoy creating systems from scratch.
- Learn quickly and execute with speed and precision.
This Role May Not Be For You If
- You prefer strict task assignments and detailed specifications before starting work.
- You want to focus only on coding tickets without product involvement.
- You prefer large teams with multiple layers of management.
Why Join Us
- Build 0 → 1 products with massive ownership.
- Work in a flat organization with no unnecessary hierarchy.
- Collaborate directly with founders and core product builders.
- Your contributions will have immediate and visible impact.
- Flexible remote work environment.
- Opportunity to shape the technology, culture, and future of the company.
If you are passionate about building powerful systems, solving complex problems, and owning your work, we would love to hear from you.
