Fintech Staff Backend / Platform Engineer (Remote – Argentina, Brazil)

Location: Remote - Argentina, Brazil

Compensation: $100,000 USD + Competitive equity

Team: Engineering

Our Client Is

Our client is a venture-backed vertical SaaS company building mission-critical system-of-record software for the debt collection and accounts receivable industry. This is a highly regulated, compliance-driven financial domain with deep technical complexity and a large, underserved market.

Backed by top-tier investors, the company has achieved strong customer traction, exceptional retention, and long-term contracts. Rather than competing with other startups, the company primarily replaces outdated legacy systems that have dominated the industry for decades.

Engineering is central to the company's success. The team is small, remote-first, and operates with high ownership, accountability, and speed.

This is a senior, hands-on role that blends:

• ~70% backend engineering
• ~30% platform / SRE responsibilities

You will function as a strong backend engineer while also owning key aspects of infrastructure, reliability, and developer tooling. This role has meaningful architectural influence and is critical to the company's growth over the next 6–12 months.
