Senior Mainframe Software Engineer information

What are the key skills and qualifications needed to thrive as a Senior Mainframe Software Engineer, and why are they important?

To thrive as a Senior Mainframe Software Engineer, you need deep expertise in COBOL, JCL, DB2, and mainframe architecture, often backed by a degree in computer science or related fields and several years of relevant experience. Familiarity with tools like IBM z/OS, CICS, RACF, and version control systems is typically required, along with certifications like IBM Certified System Programmer as a plus. Strong analytical thinking, problem-solving ability, and effective communication are crucial soft skills for leading projects and collaborating with cross-functional teams. These skills ensure reliable, secure, and efficient operation of critical legacy systems that are foundational to many large organizations.

What are some common challenges faced by Senior Mainframe Software Engineers when integrating legacy systems with modern technologies?

Senior Mainframe Software Engineers often encounter challenges when bridging legacy mainframe systems with newer technologies, such as ensuring compatibility, maintaining data integrity, and managing security risks. These integrations typically require a deep understanding of both the existing mainframe environment and the modern platforms being adopted. Collaboration with cross-functional teams, including application developers, architects, and business analysts, is essential to design effective solutions and minimize disruptions. Staying current with industry best practices and emerging tools can help address these challenges and ensure a smooth transition.

What are Senior Mainframe Software Engineers?

Senior Mainframe Software Engineers are experienced professionals who design, develop, maintain, and optimize software applications running on mainframe computer systems. They typically work with legacy programming languages such as COBOL, PL/I, or Assembler, and are responsible for ensuring the reliability, scalability, and security of critical business applications. Their role often includes troubleshooting complex issues, integrating new technologies with existing systems, and mentoring junior engineers. These specialists are essential for organizations that rely on mainframes for large-scale data processing and transaction management.

What is the difference between Senior Mainframe Software Engineer vs Mainframe Developer?

AspectSenior Mainframe Software EngineerMainframe Developer

Job description

ABOUT INTERFACE.AI

interface.ai is redefining how financial institutions serve their members through agentic AI and conversational AI - and we're doing it in production, at scale, with real outcomes. $30M in Series A funding. Cash-flow positive. A mission that matters: democratizing financial wellness for every American, not just the ones who can afford a private banker.

THE OPPORTUNITY

As a Senior Software Engineer, you're not just writing code - you're setting the technical direction for the systems you own. You'll work directly with our VP of Engineering, CTO and Co-Founder Bruce Kim, and CEO Srinivas Njay in a collaborative, in-person environment where the best ideas win and shipping is the scoreboard.

This role is for the engineer who has seen what "going fast" actually costs, knows how to build systems that hold up, and still gets things out the door.

WHAT YOU'LL WORK ON

  • Lead the design and implementation of platform services - scalable, observable, and maintainable systems that power our AI products
  • Own technical decisions end-to-end: architecture, APIs, data models, performance, and security
  • Build and extend backend systems in TypeScript and Python; shape frontend experiences in JavaScript
  • Drive the integration of LLM-based and agentic AI capabilities into production systems - this is applied AI engineering, not research
  • Define and enforce engineering standards: code review, testing strategies, deployment practices, and incident response
  • Embed AI-native tooling (Claude Code, Cursor) into your daily workflow and help the team get better at it
  • Work side-by-side with product, design, and data - in the office, in real time, every day

WHAT WE'RE LOOKING FOR

  • 5+ years of software engineering experience with a track record of shipping impactful, production-grade systems
  • A portfolio of work you led, not just contributed to - you can walk through design decisions, trade-offs, and outcomes
  • Deep proficiency in TypeScript and/or Python; solid JavaScript for frontend contributions
  • Strong platform engineering instincts: distributed systems, API design, cloud architecture (AWS/GCP), observability
  • Fluent in AI/ML engineering: you've built on top of LLMs, understand prompt engineering, and know where AI adds value - and where it doesn't
  • Experience designing systems under real constraints - latency, reliability, cost, and scale
  • BS/BA in Computer Science; graduate degree a plus (we take fundamentals seriously)
  • Self-directed and decisive: you identify problems before they're assigned, propose solutions before they're requested, and close loops without reminders
  • In SF, committed to 5 days/week - the collaboration is real and intentional

BONUS POINTS

  • Production experience with conversational AI, dialogue systems, NLP pipelines, or agentic architectures
  • Background in fintech, banking infrastructure, or regulated financial environments
  • Experience being an early engineer at a startup that shipped successfully

WHY INTERFACE.AI

You'll have real ownership, real influence, and real colleagues. We're past the existential phase - customers are live, revenue is real, and the problem we're solving is genuinely hard and genuinely important. If you want to be a cog in a machine, this is the wrong place. If you want to be the engineer who shapes how an AI company scales its platform, keep reading.

Compensation: Base $232,030 - $240,689 + Bonus + Equity + Benefits
