About Manja Technologies

Manja Technologies is a small, product-focused technology company building software solutions for smart mobility and demand-responsive transport (DRT). Our work sits at the intersection of transport operations, data analytics, and optimisation, helping improve public transportation efficiency, accessibility, and sustainability.

We are looking for a Junior Software Developer to join our close-knit team in Singapore, working closely with an Operations Research (OR) Lead on real-world transportation problems. This role is well-suited for fresh graduates or early-career engineers who are excited about applied data, algorithms, and mobility systems.

Role Overview

As a Junior Software Developer in the DRT team, you will support the development of data analytics, reporting, and optimisation algorithms that power our transport systems. You will work hands-on with operational data, build analytical tools and dashboards, and assist in developing routing and scheduling logic used in live systems.

This is a great opportunity to learn how software, data, and OR models come together in production environments.

Responsibilities

• Work closely with the OR Lead and engineering team to analyze DRT operational data and translate insights into system improvements.
• Develop and maintain Python-based analytics tools and algorithm support code.
• Write SQL queries to extract, transform, and analyze data from production databases.
• Build and maintain reports and dashboards using Apache Superset for operational monitoring and decision-making.
• Assist in developing and tuning optimisation models using Google OR-Tools (e.g. routing, assignment, scheduling).
• Support the integration of analytics and optimisation outputs into backend services and APIs.
• Participate in code reviews and contribute to clean, well-documented, and maintainable code.
• Collaborate with cross-functional teams to gather requirements and ensure successful delivery of projects.

Qualifications

• Bachelor’s degree in Computer Science, Software Engineering, or a related field.
• Strong foundation in Python programming.
• Working knowledge of SQL and relational databases.
• Interest in data analytics, algorithms, and optimisation problems.
• Basic understanding of software development principles (clean code, version control).
• Strong problem-solving skills and attention to detail.
• Good communication skills and ability to work in a small team environment.

Preferred Qualifications (Nice to Have)

• Exposure to Operations Research or optimisation techniques (academic or practical).
• Experience or familiarity with Google OR-Tools.
• Experience with BI / visualization tools such as Apache Superset.
• Understanding of transportation, logistics, or mobility systems.
• Familiarity with cloud platforms (AWS, GCP, or similar).
• Experience working in an Agile development environment.
• Knowledge of Docker or containerized applications.

Why Join Us?

• Work on real-world smart mobility and DRT systems used in production.
• Learn directly from an experienced Operations Research Lead.
• Gain hands-on exposure to data analytics, optimisation, and live transport operations.
• Be part of a small team where your contributions have real impact.
• Strong learning and growth opportunities in a niche, high-impact domain.
