Job Description

About the Role

We are looking for a highly capable Senior Software Engineer to join our Front Office team. You will be a key person responsible for modernizing legacy systems, improving code quality, handling production issues at scale, and ensuring high standards in backend engineering. Your expertise will help drive reliability, scalability, and design excellence in a critical customer-facing domain.

Key Responsibilities

Own backend design and development for mission-critical services, focusing on robustness, scalability, and maintainability.
Analyze and troubleshoot recurring production issues, perform root cause analysis, and implement long-term solutions.
Refactor and modernize legacy components and services to align with current best practices and architectural principles.
Perform technical assessments of new requirements, including feasibility analysis, effort estimation, and system impact analysis.
Set coding standards and conduct rigorous code reviews to ensure code quality and consistency.
Mentor junior developers and help build a strong engineering culture with a focus on ownership and continuous improvement.
Collaborate with frontend developers, QA, DevOps, and business stakeholders to deliver end-to-end solutions.
Identify and proactively propose technical improvements, tools, or automation opportunities beyond assigned tasks.

Requirements

Significant experience (typically 7+ years) as a backend engineer in complex environments, with a strong track record of technical ownership, system modernization, and mentoring.

Hands-on expertise with .NET Core, C#, ASP.NET Web API, and SQL Server in production-grade systems.

Proven ability to manage and refactor legacy applications, addressing technical debt and applying modern design principles.

Strong background in software architecture, system design patterns, and API design (RESTful services; microservices experience is a plus).

Skilled in database development and performance tuning using T-SQL; familiarity with PostgreSQL or migrations is a plus.

Experience in production debugging, incident analysis, and building resilient backend systems.

Strong advocate for clean code, test automation, and continuous integration.

Familiar with DevOps practices and tools (e.g., Git, Azure DevOps, CI / CD pipelines).

High sense of ownership, urgency, and accountability.

Excellent communication and collaboration skills.

Bachelor’s degree in Computer Science, Software Engineering or a related technical field.

Nice to Have

Experience with cloud platforms, especially AWS (e.g., Lambda, ECS, RDS, CloudWatch, S3).

Familiarity with PostgreSQL or prior experience migrating from MS SQL Server to PostgreSQL.

Exposure to event-driven architecture, message queues (e.g., SQS, Kafka), or asynchronous processing patterns.

Experience modernizing monolithic systems and decomposing them into modular or service-based architectures.

Knowledge of DevOps and infrastructure-as-code tools such as Terraform or CloudFormation.

Familiarity with observability tools (e.g., Datadog, ELK, Prometheus) for monitoring and diagnostics.

Why Join Us?

Be part of a critical transformation journey, modernizing a key digital onboarding product used by many.

Help shape the next-generation architecture as we transition toward AWS and PostgreSQL.

Play a technical leadership role in a lean team with real ownership, visibility, and impact.

Collaborate closely with business and product stakeholders, with the autonomy to influence solution design.

Solve real-world challenges involving legacy systems, production resiliency, and performance optimization.

Work in a culture that values engineering excellence, continuous improvement, and initiative beyond assigned tasks.
