What is a Contract Mastercard Software Engineer?

A Contract Mastercard Software Engineer is a technology professional who is hired on a temporary or project basis to develop, maintain, or improve software systems for Mastercard or its partners. These engineers typically work with payment technologies, security protocols, APIs, and large-scale transaction systems. They may be involved in designing new features, troubleshooting issues, or integrating Mastercard services with other platforms. Contract positions offer flexibility but may require specialized knowledge of payment processing and compliance standards. Such roles often involve close collaboration with both internal teams and external vendors.

What are the key skills and qualifications needed to thrive as a Contract Mastercard Software Engineer?

To thrive as a Contract Mastercard Software Engineer, you need strong proficiency in software development, payment processing technologies, and an understanding of Mastercard's platforms, often backed by a degree in computer science or related field. Familiarity with industry-standard languages (such as Java or C#), secure coding practices, and experience with Mastercard APIs or ISO 8583 protocols is typically required. Strong analytical thinking, problem-solving abilities, and effective communication skills help engineers collaborate with cross-functional teams and address complex technical challenges. These skills and qualities are crucial for ensuring secure, reliable, and innovative payment solutions that meet Mastercard's high standards.

What are some common challenges faced by Contract Mastercard Software Engineers when integrating payment solutions for clients?

Contract Mastercard Software Engineers often encounter challenges such as navigating complex compliance requirements, ensuring secure data handling, and integrating APIs with diverse client systems. Since Mastercard's payment solutions must adhere to strict security standards like PCI DSS, engineers need to stay updated on regulations and best practices. Additionally, collaborating remotely with client teams and other vendors can introduce communication hurdles, making clear documentation and proactive updates crucial for project success.

Job description

Software Guidance & Assistance, Inc., (SGA), is searching for an AI Engineer for a contract position with one of our premier banking clients in Ohio - hybrid schedule
We are looking for a AI Software Engineer to join our AI agentic engineering team. You will design and deliver guardrail components across services, define where and how enforcement should occur in systems, and mentor engineers on safe design and defensive programming patterns. You will also architect backend services, APIs, and integrations that apply software engineering discipline to govern how AI-driven systems behave across the engineering workflow.
This is a hands-on technical leadership role requiring strong proficiency in Python and TypeScript, a track record of delivering cross-service systems, and the ability to define enforcement patterns that other engineers follow.
Responsibilities:
  • Design and deliver backend services and APIs that enforce system behavior across multiple services
  • Define where and how enforcement, filtering, and validation should occur within system architectures
  • Build cross-service controls and establish the patterns other engineers implement against
  • Instrument and improve observability across service boundaries - structured logging, metrics, distributed tracing
  • Own shared tooling and platform components with broad organizational reach
  • Mentor engineers on safe design, defensive programming, and failure handling practices
Core Capabilities
  • Writes production-quality code with strong proficiency in Python and TypeScript
  • Demonstrates advanced experience working in cloud environments (AWS)
  • Demonstrates advanced experience working with Infrastructure as code tools in production environments
  • Designs and implements scalable backend services and APIs across service boundaries
  • Defines enforcement patterns and interface contracts consumed by other teams
  • Thinks in systems - reasons about cross-service dependencies, failure propagation, and contract stability
  • Communicates defensive design principles clearly to other engineers
  • Shows strong technical curiosity and forms clear, experience-backed opinions
  • What Differentiates This Role
  • This role is focused on how systems behave under misuse, failure, or unexpected inputs - not on building user-facing features. At this level, you are defining where enforcement lives and how it works across services, not just implementing within one. You bring both the technical depth to build these systems and the communication skills to make the patterns repeatable by others.

Required Skills:
  • 5-8 years of software engineering experience with strong proficiency in Python and TypeScript
  • Demonstrated experience delivering production systems on AWS (Lambda, Fargate, API Gateway)
  • Demonstrated experience building production systems on AWS using Terraform
  • Experience designing enforcement, filtering, or validation logic that spans multiple services
  • Track record of defining interfaces, contracts, or patterns adopted by other engineers
  • Ability to mentor junior and mid-level engineers on defensive design and safe coding practices
  • Clear written and verbal communication - able to define and document system-level enforcement patterns
  • Experience designing and building agentic workflows or multi-agent systems
  • Familiarity with LLM integration patterns - prompt injection detection, guardrail design, or output filtering

Preferred Skills:
  • Experience with AWS Bedrock - model invocation, guardrail configuration, or AgentCore runtimes
  • Experience with agentic or multi-step workflow systems or Background in platform engineering or developer tooling roles
