JOB OVERVIEW

# Senior Software Engineer / AI-Assisted Developer (.NET Core + GitHub Copilot + APIs)

**Location:** Remote

## About the Role

We’re looking for a highly capable software engineer who fully embraces AI-assisted software development and understands how to use modern AI tooling to dramatically accelerate delivery without sacrificing engineering quality.

This role is centered around strong software engineering fundamentals combined with practical, day-to-day use of tools like GitHub Copilot, ChatGPT, Cursor, Claude, agentic workflows, and AI-assisted development practices.

You’ll work closely with experienced engineers, product stakeholders, and operations teams to rapidly build scalable software solutions, integrations, automations, and internal tooling in a fast-moving SaaS environment.

This is not a role for someone casually experimenting with AI tools. AI-assisted development is a core expectation of the position.

---

## In This Role You Will

• Contribute to a rapidly growing application using the ---------- Core technologies

• Use GitHub Copilot and modern AI-assisted development workflows daily to accelerate software delivery

• Design and implement third-party API integrations such as Stripe, WaveApps, HubSpot, and other SaaS platforms

• Work with REST APIs, webhooks, authentication flows, and data synchronization logic

• Write clean, maintainable, testable, and well-documented production-grade code

• Collaborate with a multifaceted and talented engineering team to innovate and improve platform capabilities

• Participate in brainstorming, rapid prototyping, and technical solution design

• Debug integration and application issues while improving reliability and performance

• Contribute to CI/CD, testing strategies, and engineering best practices

• Leverage lightweight tooling such as Base44 where appropriate for operational acceleration and internal tooling

• Continuously evaluate and improve engineering productivity using AI tools, agents, and automation

---

## Basic Requirements

• 5+ years of experience in a full-time software engineering or software development role

• Strong proficiency with ASP.NET Core / C#, SQL Server, Angular 9+ / TypeScript, REST APIs, and webhooks

• Strong experience writing clean, maintainable, production-grade software

• Strong hands-on experience with modern AI-assisted development tools such as GitHub Copilot, ChatGPT, Claude, Cursor, Copilot CLI, and agentic development workflows

• Demonstrated ability to use AI tools effectively to improve development velocity and engineering quality

• Experience with unit and integration testing using NUnit or xUnit, Selenium, and Postman tests

• Strong understanding of software engineering best practices including code reviews, source control, CI/CD, build and deployment processes, testing methodologies, and operational reliability

• Strong knowledge of Azure and cloud-based environments

• Solid understanding of object-oriented programming, application architecture, database design, and software design patterns

• Strong troubleshooting and debugging skills

• Self-starter mindset with strong accountability and ownership

---

## Nice to Have

• Experience with GitHub Copilot CLI and AI agent workflows

• Experience with AspNetZero

• Familiarity with SaaS billing, payments, or accounting integrations

• Experience working with microservices or distributed systems

• Exposure to Base44 or similar low-code/no-code tooling

• Understanding of test-driven development (TDD) and QA methodologies

• Experience integrating platforms like Stripe, WaveApps, QuickBooks, HubSpot, or similar SaaS products

---

## Qualifications

• Bachelor’s degree in Computer Science, Engineering, or related field preferred

• Equivalent real-world experience is also highly valued

---

## What’s In It For You

• Exciting full-time remote opportunity

• Competitive compensation (negotiable based on experience)

• Flexible work-from-home environment

• High ownership and meaningful impact

• Opportunity to work in a modern AI-first engineering environment

• Collaborative, supportive, and open-minded engineering culture

• Work alongside talented engineers building real-world SaaS solutions at scale
