Senior Application Engineer na Monet Bank

About Monet Bank

Monet Bank is pioneering the future of banking and money movement—faster, cheaper, and crypto-native. The passage of the Genius Act has enabled a future we want to explore where interchange fees and inefficient payment rails may be replaced with a modern, programmable alternative powered by stablecoins.

At our core, we believe Monet Bank is the essential bridge between crypto and traditional finance (TradFi).

As a profitable, well-capitalized Texas state, FDIC-insured bank, Monet sees the fundamental inefficiency of the 2-3% card network payments and seeks to build a strong team to understand and pursue the future of money and banking.

See our open positions below if you want to work on the new frontier of banking projects like a stablecoin-based payment that would empower merchants to reclaim margins, Fintechs to operate cross-border at scale, and tech giants to embed crypto into their platforms without friction.

Summary:   

The Senior Application Engineer – Banking Systems is responsible for the operational stability, maintenance, and support of critical banking software applications, including the FIS core banking platform, Q2 digital banking system, and the MANTL account origination platform. In this senior role, you will manage and maintain core banking and supporting software solutions by collaborating with internal IT teams, business units, and vendors to install, update/patch, secure, monitor, troubleshoot, and optimize these application environments. A key focus is ensuring high availability of customer-facing digital banking services (online and mobile banking) through proactive monitoring, timely incident resolution, and continuity planning. This position also leads efforts in integrating new features or third-party solutions into the banking systems and guarantees that upgrades or changes meet technical requirements without disrupting existing services. Strong technical acumen, problem-solving abilities, and effective communication skills are essential for success in this role. This is a full-time, permanent position based on-site in Plano, TX, working closely with both business stakeholders and technology vendors to support the bank’s core and digital platforms.

Essential Duties and Responsibilities:  

• System Patching & Upgrades: Plan and execute regular maintenance activities, including applying vendor patches and software upgrades for the core banking system (FIS) and related platforms. Coordinate testing and rollout of updates to ensure minimal downtime and compliance with change management procedures. Continuously install and update application components as needed to keep systems current and secure.
• User Access Management & Security: Administer user accounts, roles, and access permissions across FIS core, Q2, and MANTL systems. Ensure proper role-based access controls are in place and conduct periodic access reviews to maintain compliance with bank policies and regulatory standards. Enforce data security and privacy controls within these applications, aligning with IT policies and security standards required in the banking sector.
• Integration Management: Oversee and support integrations between the core banking platform and auxiliary systems such as the Q2 digital banking platform and the MANTL origination software. Ensure new software integrations or third-party interfaces meet functional requirements and do not disrupt existing processes. Work with vendors and internal teams to achieve seamless data flow – for example, enabling MANTL’s account origination to smoothly integrate with Q2 online banking for a seamless onboarding experience. Develop an understanding of file transfer processes, APIs, and data mappings between systems to troubleshoot and optimize integrations.
• Performance Tuning & Monitoring: Continuously monitor application performance, system logs, and interfaces to detect and prevent service disruptions proactively. Perform application configuration adjustments and tuning to optimize system performance and response times. Establish routine checks and use monitoring tools to ensure high availability and stability of all digital banking applications (e.g., core processing, online banking, mobile banking). Address performance bottlenecks by coordinating with infrastructure teams (network, database, server admins) as needed.
• Technical Support & Troubleshooting: Serve as the top-tier (Tier 2/3) support contact for core banking and digital banking application issues. Investigate and resolve incidents or service requests related to FIS core, Q2, and MANTL systems, within defined service level objectives. When necessary, escalate issues and work closely with vendor support (FIS, Q2, MANTL) to expedite problem resolution. Provide in-depth troubleshooting, root cause analysis, and implement corrective actions for recurring issues. As a Senior Administrator, you will also provide Tier 3 support for core systems and mentor or train junior staff in handling complex issues.
• Vendor Coordination & Planning: Act as a primary liaison with software vendors (FIS, Q2, MANTL) for product support, patches, and upgrades. Manage vendor relationships to ensure timely assistance on technical issues and keep abreast of product roadmaps and upcoming changes. Lead and coordinate early-adopter testing or beta programs with vendors for new features or updates in the digital banking platform, ensuring the organization is prepared for new releases. Plan and schedule upgrade projects, working with vendors and cross-functional internal teams to execute deployment and post-update validation.
• Documentation & Compliance: Maintain comprehensive system documentation, including configuration settings, integration workflows, maintenance schedules, and standard operating procedures. Document all changes, incidents, and resolutions for future reference and auditing purposes. Ensure all application administration activities adhere to the bank’s IT governance, change control processes, and compliance requirements. This includes ensuring that new functionality and changes meet compliance standards and regulatory guidelines. Participate in audits and provide necessary information or reports related to application access, changes, and performance.
• Continuous Improvement: Review existing application setups for effectiveness and identify opportunities to improve or streamline processes. Work closely with business analysts and end-users to understand pain points and emerging requirements. Lead or assist in projects to implement new modules or enhancements to FIS, Q2, or MANTL systems that support business needs, coordinating user acceptance testing and end-user training for new features. Stay up-to-date with industry best practices in banking technology and recommend improvements in system usage, configuration, or automation.

• Education: Bachelor’s degree in Computer Science, Information Systems, or a related field. Equivalent work experience combined with relevant certifications may be considered.
• Experience: Minimum 7-9 years of experience in Information Technology, with at least 4-6 years in application support or systems administration of core business applications. Prior experience in the banking or financial services industry supporting core banking systems or digital banking platforms is highly preferred.

• Technical Proficiency: Strong hands-on experience with enterprise Windows Server environments, including familiarity with Active Directory, DNS, IIS, and related Microsoft infrastructure. Solid understanding of three-tier application architectures and network technologies as they relate to deploying and supporting integrated banking applications.

Basic scripting skills (PowerShell, Bash, or similar) to automate routine tasks or data extracts are expected.
• Banking Systems Knowledge: Demonstrated experience administering or supporting banking software such as FIS core banking platforms (or similar core processing systems), digital banking platforms like Q2, or account origination systems (e.g., MANTL or similar). Understanding of online banking, mobile banking, and account opening workflows from a systems perspective is essential. Familiarity with vendor-specific admin consoles and tools (for example, experience with a core banking application stack like Fiserv DNA is a plus) will help you ramp up quickly in this role.
• Problem Solving & Support Skills: Proven ability to troubleshoot complex application issues in a high-pressure, critical environment. Experience providing Tier 2/3 application support or acting as an escalation point for difficult issues. Able to perform root cause analysis and permanently resolve recurring problems. A service-oriented mindset and strong analytical skills are required to effectively support end-users and optimize system usage.
