About Onsetto

Onsetto is building a white-label, AI-powered platform that simplifies and accelerates commercial bank account switching. We automate complex AR, AP, and payroll transitions so financial institutions can win more business, grow deposits, and establish primacy—with bank-grade reliability.

Our systems sit directly in critical financial workflows. Reliability, security, and operational discipline are part of the product.

We operate at the intersection of:

• AI systems running in real production environments
• Regulated financial systems requiring auditability and control

What we build must work consistently, under real constraints, at scale.

About the Role

This role is for engineers who can independently own meaningful parts of a system.

As an Engineer II, you are expected to move beyond execution and take responsibility for how systems behave in production. You will design, build, and improve services while owning their reliability, performance, and long-term maintainability.

You will work across backend systems, infrastructure, and reliability, with increasing responsibility for decision-making and system design.

You are not just implementing tasks—you are accountable for outcomes.

What You Will Do

• Design, build, and maintain backend services and APIs
• Own specific systems or components, including their reliability in production
• Debug complex issues across services, infrastructure, and data flows
• Improve system performance, scalability, and fault tolerance
• Contribute to CI/CD pipelines, deployment processes, and release quality
• Use LLM tools effectively to accelerate development while maintaining quality
• Participate in incident response and lead root cause analysis efforts
• Collaborate with product and engineering to define clear, testable solutions
• Contribute to system design decisions and technical tradeoffs

What We Are Looking For

• 3–5 years of experience building production software systems
• Strong proficiency in at least one backend language (Python preferred)
• Experience designing and building APIs and working with databases
• Solid understanding of system design fundamentals (scalability, reliability, failure modes)
• Ability to debug across layers (application, infrastructure, data)
• Demonstrated ownership of systems or major features
• Comfort working in environments with real operational constraints

Strong Signals

• You have owned a system or service in production
• You proactively identify and fix reliability or performance issues
• You think in terms of tradeoffs, not just implementation
• You improve systems beyond your immediate scope
• You use tools (including AI) to increase speed without sacrificing quality
• You help raise the bar for those around you

What Success Looks Like

• Systems you own are stable, reliable, and well understood
• Production issues are identified, resolved, and learned from quickly
• You reduce dependency on more senior engineers for execution
• You make sound technical decisions with limited guidance
• You improve how the team builds, tests, and ships software

How We Work

We operate with a small set of principles:

• Focus on a small number of important goals
• Measure what matters and make it visible
• Own outcomes, not just activity
• Ship consistently and improve through discipline

You are expected to lead by example in how you apply these principles.

Who Should NOT Apply

• You are looking for a purely remote role
• You prefer narrowly scoped tasks over system-level ownership
• You are not interested in production responsibility or operational accountability
• You rely heavily on direction for technical decisions
• You avoid debugging complex, ambiguous problems
• You are not interested in improving systems beyond your assigned work

Compensation

• Competitive, market-aligned salary for Columbus, Ohio
• Additional compensation and growth tied to performance and impact

Why This Role

This is an opportunity to become a strong mid-level engineer by owning real systems.

You will work on infrastructure and applications used by financial institutions, operate under real constraints, and develop the judgment required to design, build, and maintain production systems.

If you want to take the step from contributor to owner—and are willing to be held accountable for system outcomes—this is the role.
