Algorithm Engineer

Working arrangement: Thailand (Hybrid — remote + in-office at our Thailand office)

Design Algorithms That Power Smarter, Faster, Fairer Financial Systems

At BJAK, we’re on a mission to simplify financial services through intelligent, scalable systems that reach millions across Southeast Asia. As an Algorithm Engineer, you’ll design the core logic behind everything from personalization and optimization to fraud detection and pricing models. You’ll be part of a lean, high-impact team where your decisions directly shape real-world outcomes.

This is a Hybrid role based in Thailand, collaborating closely with our HQ in Malaysia and regional product, data, and engineering teams.

• You’ll design mission-critical algorithms that influence accuracy, efficiency, and decision-making

• Your work will directly shape high-impact product features used by millions

• You’ll collaborate across engineering, data, and product to solve meaningful, real-world problems

• You’ll contribute to scalable, production-grade systems with measurable business impact

• Design and implement algorithms to solve product and business challenges

• Tackle problems in optimization, search, recommendation, pricing, and risk modeling

• Translate complex, real-world problems into structured algorithmic solutions

• Analyze trade-offs, edge cases, and performance constraints to guide design decisions

• Write clean, scalable, and efficient code to support algorithm development

• Work with software engineers and data scientists to integrate algorithms into live systems

• Continuously iterate on algorithms based on feedback, testing, and live data

• Stay informed on advances in algorithm design, data structures, and applied research

• Love solving tough, real-world problems through structured, elegant algorithm design

• Take ownership from end to end — from theory to production impact

• Are curious, adaptable, and constantly pushing to level up your technical capabilities

• Can work through ambiguity and figure things out without waiting for instruction

• Embrace startup speed — fast changes, tight feedback loops, and quick iteration energize you

• Enjoy collaborating with humble, driven teammates who share knowledge freely

• Proactively seek better solutions, even outside your current expertise

• Turn chaos into structure and messy problems into scalable systems

• Bachelor’s or Master’s degree in Computer Science, Mathematics, Engineering, or related field

• 2–4 years of experience in algorithm development, backend engineering, or system design

• Proficient in Python (preferred), C++, or Java

• Deep understanding of algorithms, data structures, complexity analysis, and optimization

• Hands-on experience solving applied problems in recommendation, ranking, search, or pricing

• Familiarity with numerical methods, statistical analysis, or mathematical modeling

• Comfortable working with large-scale data and real-world constraints

• Must be a Thai citizen

• Must be willing to work hybrid from our Thailand office while collaborating with the Malaysia team

• Experience with machine learning, statistical modeling, or data mining

• Familiarity with optimization solvers, constraint programming, or heuristic algorithms

• Exposure to cloud platforms, production systems, or microservices architecture

• Prior experience in high-growth startups or product-focused engineering teams

• Competitive salary and performance-based bonuses

• Hybrid work model — flexible remote + collaborative office time

• High-impact work and real visibility across the company

• Flat structure where your ideas are heard and implemented fast

• Steep learning curve with complex algorithmic challenges

• Cross-functional exposure and collaboration across ASEAN markets
