Senior Backend Engineer – Fintech Infrastructure & Payments Platform

Andiamo is hiring on behalf of a client that is transforming how money moves throughout the higher education ecosystem. This rapidly growing fintech organization is building modern financial infrastructure that simplifies the exchange of funds between educational institutions, students, families, scholarship providers, government agencies, and financial organizations.

This is an opportunity to help architect and scale mission-critical systems in a market that has historically relied on fragmented processes, manual workflows, and outdated technology. You'll join a high-performing team that is reimagining how financial transactions, disbursements, and payment operations are managed across one of the largest sectors of the economy.

The Opportunity

We are seeking a Senior Backend Engineer who thrives on ownership, enjoys solving complex systems challenges, and wants to build foundational technology that supports large-scale financial transactions. This is not a maintenance-focused role. You will have significant influence over architecture, platform strategy, engineering practices, and product direction while working closely with company leadership and a highly collaborative engineering team.

If you enjoy building systems from the ground up, operating in a fast-moving environment, and solving meaningful real-world problems, this role offers the chance to make a lasting impact.

What You'll Build

You will help design and evolve the core infrastructure that powers a modern financial network, including:

• Payment processing and transaction orchestration platforms.
• Secure financial data exchange systems.
• High-performance APIs supporting institutional and third-party integrations.
• Banking and payment network connectivity.
• Authentication, authorization, and identity services.
• Developer tooling, automation, and platform services.
• Infrastructure and observability systems that ensure reliability and scalability.
  
  

Key Responsibilities

Platform Architecture & Engineering

• Design and implement scalable backend systems that support high-volume financial operations.
• Build resilient APIs, services, and workflows that power critical payment and settlement activities.
• Develop robust data models, processing pipelines, and service architectures capable of supporting future growth.
• Drive technical design decisions that balance performance, maintainability, security, and business objectives.
• Continuously improve platform reliability, scalability, and operational efficiency.
  
  

Infrastructure & Reliability

• Own production systems from design through deployment, monitoring, and ongoing optimization.
• Develop automation, deployment pipelines, and engineering workflows that accelerate delivery while maintaining quality.
• Implement monitoring, alerting, logging, and observability solutions that provide actionable operational visibility.
• Strengthen disaster recovery, resilience, and incident response capabilities.
• Identify and eliminate operational bottlenecks through automation and system improvements.
  
  

Product & Business Collaboration

• Partner with product, operations, and leadership teams to translate business challenges into elegant technical solutions.
• Contribute to product strategy discussions and help prioritize initiatives based on customer impact and business value.
• Participate in customer conversations when needed to better understand user needs and operational challenges.
• Help shape new platform capabilities, integrations, and financial products.
  
  

Engineering Excellence

• Champion software craftsmanship, code quality, testing, and engineering best practices.
• Lead by example through thoughtful architecture, clean code, and strong ownership.
• Mentor teammates and contribute to a culture of continuous learning and technical excellence.
• Promote pragmatic decision-making and iterative product development.
  
  

Who You Are

You are a builder who enjoys taking ideas from concept to production. You combine strong technical judgment with a practical mindset and understand that great products are created through rapid learning, customer feedback, and continuous improvement.

You are energized by ownership, comfortable operating with autonomy, and motivated by solving meaningful problems rather than simply completing assigned tasks.

Required Qualifications

• 7+ years of professional software engineering experience, including significant backend development experience.
• Demonstrated success designing, building, and scaling production-grade backend systems.
• Strong expertise with Node.js and modern TypeScript or JavaScript development.
• Experience developing APIs, distributed services, data processing systems, and production applications.
• Deep knowledge of PostgreSQL and Redis in high-performance environments.
• Experience owning software throughout its lifecycle, including architecture, implementation, deployment, monitoring, and optimization.
• Excellent communication and collaboration skills.
• Strong prioritization, project ownership, and execution capabilities.
  
  

Preferred Qualifications

• Experience building cloud-native systems using AWS or similar cloud platforms.
• Hands-on experience with infrastructure-as-code tools such as Terraform.
• Knowledge of CI/CD pipelines, release automation, and DevOps practices.
• Experience working in fintech, banking, payments, financial services, or other regulated industries.
• Understanding of payment processing, money movement, identity verification, authentication, or financial infrastructure.
• Experience building products from inception through commercial scale.
• Previous experience working within startup or high-growth environments.
  
  

Technology Environment

• Backend: Node.js, TypeScript, Ruby on Rails, Sidekiq
• Data: PostgreSQL, Redis
• Cloud & Infrastructure: AWS, Docker, Terraform
• Frontend: React, TypeScript

What Makes This Opportunity Unique

• Build foundational financial infrastructure in a massive and underserved market.
• Work directly with experienced founders and senior decision-makers.
• Influence architecture, product strategy, and engineering culture.
• Solve technically challenging problems involving payments, integrations, scalability, and compliance.
• Join a company at an exciting stage of growth with significant opportunities for impact and career advancement.
  
  

Compensation & Benefits

Base Salary: $170,000 - $220,000

Equity: Competitive equity package available.

• Medical, dental, and vision coverage.
• Health savings and flexible spending account options.
