BJAK is seeking an Algorithm Engineer to design core algorithms that power intelligent, scalable financial systems for millions of users across Southeast Asia. You will solve complex, ambiguous problems in personalization, optimization, fraud detection, and pricing.

What You'll Do

Design and implement algorithms to solve business-critical problems across personalization, optimization, pricing, and search.
Convert ambiguous product challenges into clear, structured algorithmic solutions.
Analyze trade-offs between accuracy, speed, scalability, and implementation complexity.
Write clean, efficient, production-grade code for algorithm logic.
Collaborate with data scientists and engineers to integrate and validate algorithms.
Continuously refine and improve logic based on testing, feedback, and new data.
Stay on top of relevant research, trends, and techniques in algorithms, statistics, and modeling.

What We're Looking For

Bachelor’s or Master’s degree in Computer Science, Mathematics, Engineering, or a related technical field.
2 - 4 years of experience in algorithm design, backend engineering, or systems development.
Proficient in Python, or Javascript (Python preferred).
Strong foundation in algorithms, data structures, complexity analysis, and optimization techniques.
Experience solving real-world problems in recommendation, ranking, search, pricing, or similar domains.
Familiarity with mathematical modeling, statistical analysis, or numerical methods.
Comfortable working with large datasets, edge cases, and production-level constraints.
Must be based in Hong Kong and open to remote collaboration with regional teams.

Nice to Have

Background in ML, data mining, or statistical modeling.
Familiarity with optimization solvers, graph algorithms, or constraint programming.
Experience with cloud infrastructure, containerization, or distributed systems.
Startup or high-growth environment experience.
