Lead Software Engineer

Alternative Payments is building the financial operating system for SMBs, consolidating the disconnected tech stack that holds service-based businesses back. Starting with MSPs, we've spent five years perfecting accounts receivable, and we're now expanding into accounts payable, AI-powered analytics, and beyond. We're at an inflection point: closing the loop on money movement and laying the foundation for a platform that will reshape how service businesses operate financially. We're growing fast, thinking big, and building a global team that wants to be part of something that lasts. We believe the best solutions come from diverse perspectives, deep collaboration, and a shared obsession with customer impact. If you're energized by real problems, real customers, and real impact, we want to hear from you! What you'll do We're looking for a Lead Software Engineer who's as comfortable talking about how a business makes money as they are designing a distributed system. This is a hands-on technical leadership role: you'll own initiatives end-to-end, partner closely with product, and help set the technical direction for a team that moves fast and operates with high autonomy. You'll report to our VP of Engineering and work in a flat structure where ICs lead projects, not just contribute to them. We run parallel initiatives at any given time in small, two-person tribe structures. We expect the people who join us to be the kind who step up, make decisions, and take accountability for outcomes, technical and otherwise. Own complex technical initiatives from conception to delivery, including architecture decisions, implementation, and cross-functional coordination with product and business stakeholders. Lead cross-functional efforts (tiger teams and initiative-based squads) and serve as the technical point of accountability for the initiatives you're running. Design and implement scalable microservices solutions, with particular attention to reliability, performance, and maintainability in a high-volume financial transactions environment. Partner with the product to understand the business context and translate it into technical decisions. This means understanding why something matters to the business, not just what needs to be built. Raise the technical bar across the team through code review, architecture feedback, and knowledge sharing with less senior engineers. Leverage AI tooling as a core part of how you work. We're an AI-forward team and expect you to have a sophisticated, evolved setup, not just basic usage. What you'll bring 8+ years of software engineering experience, ideally including time at a fintech, high-growth startup, or company operating at scale. Proficiency in Golang, Rust or openness to work with it . Experience designing and evolving scalable architectures — microservices, distributed systems, or monoliths — with a clear point of view on the tradeoffs of each. Hands-on experience with Kubernetes, PostgreSQL, and cloud platforms (we're on AWS ). Demonstrated ability to lead a project from soup to nuts. This means technical execution, stakeholder communication, and delivery accountability. Business acumen : you understand how software products make money, you care about it, and it informs how you make technical decisions. English communication skills sufficient to collaborate effectively with our teams in the US, Canada, and Brazil (our engineering team is based in Brazil!). Experience in fintech or payments is a strong plus, but the more important signal is whether you've worked somewhere that expected you to understand the full picture. Nice-to-haves Background as an Engineering Manager, Staff Engineer, Lead Engineer or Tech Lead with a desire to return to hands-on technical work. Experience at companies serving US-based markets. Familiarity with the communication norms and business context that come with that. Comfort with event-driven architectures (RabbitMQ or similar). A sophisticated AI-assisted workflow: multiple models, custom agents, specialized contexts , integrated into planning and implementation, not just Copilot autocomplete. Track record of mentoring engineers and raising team output , not just individual output. What we offer Competitive salary tailored to your experience, skills, and expertise. The total compensation range for this role is 90k – 102k USD, plus equity. The range displayed on each job posting reflects the approximate total target compensation for the position. Within the range, individual pay is determined by factors including relevant skills, experience, education/training. Equity opportunities so you can share in our growth and success.
