Job Description

About Truelogic

At Truelogic we are a leading provider of nearshore staff augmentation services headquartered in New York. For over two decades, we’ve been delivering top-tier technology solutions to companies of all sizes, from innovative startups to industry leaders, helping them achieve their digital transformation goals.

Our team of 600+ highly skilled tech professionals, based in Latin America, drives digital disruption by partnering with U.S. companies on their most impactful projects. Whether collaborating with Fortune 500 giants or scaling startups, we deliver results that make a difference.

By applying for this position, you’re taking the first step in joining a dynamic team that values your expertise and aspirations. We aim to align your skills with opportunities that foster exceptional career growth and success while contributing to transformative projects that shape the future.

Our Client

They are a high-growth fintech startup transforming how e-commerce brands protect and recover their revenue. Their platform automates chargeback prevention and dispute response, turning what has traditionally been a manual and frustrating process into a fast, intelligent, and efficient workflow.

Job Summary

We’re looking for a Senior Software Engineer who thrives in fast-paced environments and enjoys taking ownership of complex, business-critical systems. In this role, you’ll own a key area of our payments dispute resolution platform and help evolve it into a stable, scalable, and reliable product.

You’ll be one of the first LATAM-based engineers joining a small, high-impact team that collaborates closely with an offshore development partner. Our current codebase is a production-ready PHP/CodeIgniter system that grew quickly with a lean team—so yes, there’s technical debt, limited test coverage, and performance challenges. If improving and modernizing real-world systems excites you more than it scares you, this role is for you.

Responsibilities

• Take full ownership of a core business domain and drive it toward stability and reliability

• Write, review, and refactor code while resolving production issues

• Systematically reduce technical debt without slowing down product delivery

• Collaborate closely with our offshore development team

• Make pragmatic technical decisions that balance short-term impact with long-term maintainability

• Build foundational testing, monitoring, and documentation that currently don’t exist

Qualifications and Job Requirements

• 5+ years of professional software engineering experience;

• Experience working at a high-growth or scaled company;

• Strong fundamentals across multiple languages and framework, specially PHP/CodeIgniter and Ruby on Rails;

• Proven track record of ownership and delivering projects end-to-end;

• Comfort working independently and making decisions with imperfect information;

• Availability to work in US or Canada time zones (fully remote).

Familiarity with MySQL/Aurora and AWS environments is a plus.

What We Offer

• 100% Remote Work: Enjoy the freedom to work from the location that helps you thrive. All it takes is a laptop and a reliable internet connection.

• Highly Competitive USD Pay: Earn an excellent, market-leading compensation in USD, that goes beyond typical market offerings.

• Paid Time Off: We value your well-being. Our paid time off policies ensure you have the chance to unwind and recharge when needed.

• Work with Autonomy: Enjoy the freedom to manage your time as long as the work gets done. Focus on results, not the clock.

• Work with Top American Companies: Grow your expertise working on innovative, high-impact projects with Industry-Leading U.S. Companies.

Why You’ll Like Working Here

• A Culture That Values You: We prioritize well-being and work-life balance, offering engagement activities and fostering dynamic teams to ensure you thrive both personally and professionally.

• Diverse, Global Network: Connect with over 600 professionals in 25+ countries, expand your network, and collaborate with a multicultural team from Latin America.

• Team Up with Skilled Professionals: Join forces with senior talent. All of our team members are seasoned experts, ensuring you're working with the best in your field.
