THE OPPORTUNITY

Tachyon Technologies is seeking a Senior Full Stack Engineer who combines advanced coding skills with application design expertise and strong analytical problem-solving. You will own technically challenging features, shape engineering decisions and guide developers while remaining actively involved in writing, reviewing, testing and debugging production code. This is a hands-on senior engineering role—not an architecture-only or people management position.

WHAT YOU WILL BUILD

Scalable enterprise applications, portals and cloud services with secure integrations, complex business workflows and reliable production operations. Opportunities may include AI-enabled applications and reusable engineering solutions.

KEY RESPONSIBILITIES

• Personally design and implement complex frontend and backend features using React/TypeScript and Python or .NET.
• Own application-level design: service boundaries, API contracts, database models, security and system integrations.
• Translate business requirements into implementable technical designs, identifying risks and sensible trade-offs.
• Solve advanced engineering problems involving performance, concurrency, reliability and production defects.
• Guide a small engineering team through code reviews, pair debugging, technical mentoring and quality standards.
• Build reusable components and services, with strong automated testing, observability and maintainability.
• Lead cloud deployment and technical troubleshooting across Azure or AWS, Docker and CI/CD workflows.
• Collaborate with product, architecture and delivery teams on technical estimates, milestones and solution workshops.

REQUIRED SKILLS & EXPERIENCE

• 10+ years of software engineering experience with demonstrable, recent hands-on coding across frontend and backend.
• Excellent React, TypeScript and JavaScript skills, including frontend architecture and performance optimization.
• Deep Python (FastAPI/Django) or C#/.NET Core expertise; secure APIs, integrations and asynchronous processing.
• Strong SQL, data modeling, query tuning, API design and database transaction fundamentals.
• Strong software design fundamentals: OOP, SOLID, design patterns, data structures and algorithms.
• Proven application/system design, troubleshooting, root-cause analysis and production ownership.
• Hands-on Azure or AWS, security, CI/CD, Docker, automated testing, logging and monitoring.
• Ability to mentor engineers and make sound design decisions without stepping away from implementation.

GOOD TO HAVE

• Microservices, event-driven systems, Kubernetes, Terraform and large-scale SaaS/enterprise platforms.
• LLM integrations, RAG, agent workflows, Azure AI/AWS Bedrock and AI-assisted development practices.

WHAT WE VALUE

Technical depth with a builder mindset. We value engineers who can explain why a design works, demonstrate the code they personally contributed, challenge assumptions constructively and raise the engineering bar through example.

SELECTION PROCESS Hands-on coding, practical debugging, system design and discussion of real projects you have personally delivered.
