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.

Why This Role Matters

• 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

  What You’ll Do

  • 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

    You’ll Thrive Here If You...

    • 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

      Requirements

      • 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

        Nice to Have

        • 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

          What You’ll Get

          • 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
