Modern Cloud Native
Backend development today is typically built around cloud-hosted services, containers, CI/CD, and distributed systems, but AI is usually only an optional integration rather than the core of the role.

Job description

Crossover is the world's #1 source of full-time remote jobs. Our clients offer top-tier pay for top-tier talent. We're recruiting this role for our client, Trilogy. Have you got what it takes?

“Coding competitions are for university students” - Wrong.

“Competitive programming is a sport for your free time. Building a software development career is something completely different” - Incorrect.

“Software developers work in Agile teams. You need to collaborate and participate in daily project and team meetings.” - Not when you are with us.

Trilogy uses cloud-native technologies to improve software products for dozens of customers, and we are looking for veteran competitive programmers to help us. We have reinvented the software development process to break down product specs and milestones into individual code challenges with 4-8 hour SLAs, and your job is to crack the problem and beat the clock. It’s no different from a coding competition - except for the US$200k salary and the chance to double your compensation as you move up the Engineering ladder.

The future of work started long ago with us. Home office twice a week? We have been working from wherever we want for the last fifteen years in our 100% remote model. While scrum rituals and daily standups are still dominating the rest of the industry, our team is already operating under a global asynchronous model where each developer follows 8-hour shifts three or four days a week, plans the rest of their workweek flexibly, and never exceeds 40 hours. The development operates 24x7, but you are free to choose your own schedule!

What You Will Be Doing

• Designing innovative commercial software and writing high-quality code to bring them into production.
• Implementing new features on existing software products by solving complex implementation problems and making the appropriate technical decisions.
• Fixing bugs to permanently eliminate defects that impair product functionality.


What You Won’t Be Doing

• Dealing with unclear expectations or non-technical managers. Every task will have a clear scope and objective for you to implement.
• Executing repeated tasks for the same product using the same tech stack. Our portfolio of 60+ products ensures you are always tackling new challenges.
• Non-technical tasks. This is a role for those who love coding and want to dedicate time to solving complex technical issues.


C# Developer key responsibilities

Solve the most difficult coding challenges and develop great software products that delight millions of customers.

Basic Requirements

• 5+ years of commercial software development experience
• Experience in competitive programming proven by placement in ICPC, ICPF, TopCoder, or another renowned coding competition
• Availability to work during US business hours


About Trilogy

Hundreds of software businesses run on the Trilogy Business Platform. For three decades, Trilogy has been known for 3 things: Relentlessly seeking top talent, Innovating new technology, and incubating new businesses. Our technological innovation is spearheaded by a passion for simple customer-facing designs. Our incubation of new businesses ranges from entirely new moon-shot ideas to rearchitecting existing projects for today's modern cloud-based stack. Trilogy is a place where you can be surrounded with great people, be proud of doing great work, and grow your career by leaps and bounds.

There is so much to cover for this exciting role, and space here is limited. Hit the Apply button if you found this interesting and want to learn more. We look forward to meeting you!

Working with Crossover

This is a full-time (40 hours per week), long-term position. The position is immediately available and requires entering into an independent contractor agreement with Crossover. The compensation level for this role is $100 USD/hour, which equates to $200,000 USD/year assuming 40 hours per week and 50 weeks per year. The payment period is weekly. Consult www.crossover.com/help-and-faqs for more details on this topic.

What to expect next:

• You will receive an email with a link to start your self-paced, online job application.
• Our hiring platform will guide you through a series of online “screening” assessments to check for basic job fit, job-related skills, and finally a few real-world job-specific assignments.


Important! If you do not receive an email from us:

• First, emails may take up to 15 minutes to send, refresh and check again.
• Second, check your spam and junk folders for an email from Crossover.com, mark as “Not Spam” since you will receive other emails as well.
• Third, we will send to whatever email account you indicated on the Apply form - by default, that is the email address you use as your LinkedIn username and it might be different than the one you have already checked.
• If all else fails, just reset your password by visiting https://www.crossover.com/auth/password-recovery if you already applied using LinkedIn EasyApply.
