Senior Backend Java/Python Engineer

At Codelitt , we partner with ambitious companies to build digital products that solve real business problems. Our teams care deeply about product quality, strong engineering, and working closely with stakeholders to ship meaningful outcomes.

About the Role

We’re looking for a Senior Backend Engineer (Java & Python) to join our team on a high-impact engagement with one of our partners, a global wealth-tech and data platform that helps investment professionals manage complex portfolios, deliver better client experiences, and operate at scale.

The company supports a large international client base, serving more than 1,400 firms across 60+ markets , and continues to invest heavily in client-facing products, integrations, and AI-enabled workflows.

This role will embed with a senior engineering team responsible for expanding core advisor and client experiences across web and mobile platforms. Rather than working in a single monolithic codebase, you will contribute across multiple backend services and platforms , building and evolving systems implemented in Java and Python .

You’ll help design and deliver backend capabilities, integrations, and platform improvements that support real product outcomes — not just isolated features. This is a hands-on engineering role with meaningful ownership, visible impact, and strong collaboration across teams.

Who You Are

• Backend-first engineer with strong production experience in Java and/or Python
• Comfortable working across multiple services, systems, and codebases
• Pragmatic and able to navigate complex or evolving architectures
• Experienced with APIs, integrations, and distributed backend systems
• Strong at building reusable platform capabilities, not just feature-by-feature implementations
• Comfortable using AI tools to accelerate development while applying sound engineering judgment
• Collaborative, low-ego, and able to integrate quickly into an experienced engineering team
• Focused on delivering business value through reliable, maintainable systems

What You’ll Do

Backend Platform Development

• Design, build, and extend backend services across multiple systems implemented in either Java or Python
• Deliver clean, maintainable solutions that support new product capabilities
• Improve platform reliability, scalability, and maintainability
• Contribute to system design decisions and architectural evolution

Integrations & Data Flows

• Implement and maintain integrations between internal services and external platforms
• Design reliable data flows across services and systems
• Improve resilience, observability, and ownership across service boundaries
• Help evolve backend patterns that support long-term platform growth

Cross-Functional Delivery

• Work closely with engineering leads, product managers, designers, and stakeholders to refine requirements and deliver incrementally
• Support delivery of high-priority initiatives with clear timelines and measurable impact
• Participate in technical discussions, tradeoff decisions, estimation, and planning
• Contribute to improving development workflows and team velocity

Engineering Quality

• Write testable, maintainable, and well-documented code
• Help maintain strong engineering standards while enabling fast delivery
• Contribute to code reviews, technical design discussions, and knowledge sharing
• Bring a product mindset to backend work, balancing user experience, performance, and reliability

Preferred Qualifications

• 5+ years of professional software engineering experience
• Strong experience in Java and/or Python backend development
• Experience working with multiple backend services, APIs, or distributed systems
• Solid background in system integrations and data modeling
• Experience integrating with SaaS platforms, internal systems, or third-party services
• Familiarity with cloud environments, CI/CD pipelines, and modern development practices
• Experience working in product-driven engineering teams
• Exposure to fintech, wealth tech, or other data-intensive B2B SaaS products is a strong plus

Nice to Have

• Experience with microservices or service-oriented architectures
• Experience with event-driven systems or asynchronous processing
• Experience improving legacy systems or evolving platform architectures
• Familiarity with observability tooling (logging, metrics, tracing)
• Experience working in high-growth or scaling engineering environments

Soft Skills

• Strong problem-solving skills and sound technical judgment
• Clear communicator who works effectively with both technical and non-technical stakeholders
• Comfortable with ambiguity, changing priorities, and real delivery pressure
• Ownership mindset with a bias toward action
• Team-oriented and easy to work with in a remote environment

Why This Role Matters

This is an opportunity to join a meaningful engagement with:

• Immediate, real-world delivery impact
• A senior partner engineering team
• Modern backend systems across multiple services
• Clear ownership and technical influence
• A product-focused engineering culture
