Remote Python Financial Jobs Near Me

Who We Are

At Onsetto, we're building more than technology, we're building the future of business banking.

Trusted by financial institutions across the country, Onsetto is helping banks grow deposits, win operating relationships, and transform how they serve businesses. Following our recent $9 million seed funding round, we're entering an exciting new phase of growth and looking for ambitious, entrepreneurial people who want to help shape what comes next.

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

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.

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.

What We Are Looking For

• 35 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

Extra Credit

• 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

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

What You Can Expect

• The opportunity to take real ownership of your work and make a visible impact

• Broad hands-on experience across multiple areas of the business

• The ability to help shape processes, systems, and how the company operates

• Direct exposure to leadership and strategic decision-making

• A high-trust environment with low bureaucracy and meaningful responsibility

• A team that values accountability, clarity, consistency, and strong execution

• Flexible PTO

• Medical, dental, and vision coverage for eligible employees

• Access to HSA plan options

• Paid parental leave

• An environment best suited for people who want to build, improve, and contribute beyond a narrow job description

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 for you.
