Joining us means gaining access to the ins and outs of the entire transportation industry. As part of a global team of industry experts, you get to think bigger, experience more, and reach further. Being bigger also means being stronger. Together with our brands, we have the collective power to transform transportation. Find out more: www.traton.com

Role Summary

We develop software that is central to how transport companies plan and operate electrified heavy-duty truck fleets. Our systems are designed to be used daily as part of our customers’ core transport operations and directly influence how planning and execution decisions are made.

Our mission is to create the shift to a sustainable transport system through better planning and use of transportation resources. The software we build is a key enabler of that shift and must therefore be correct, predictable, and efficient in real use.

In this role, you will design, implement, and evolve both algorithms and the systems that run them. You will work with optimization problems such as routing, charging, and fleet-level planning, and take responsibility for how these solutions behave in production — from modeling and algorithmic choices to operational reliability.

The role comes with real technical responsibility and the expectation that you actively influence technical direction and solution design.

Job Responsibilities

· Design, implement, and evolve optimization algorithms for routing, charging, and fleet-level planning

· Work with algorithmically hard problems such as electric vehicle routing, resource-constrained planning, and large-scale re-optimization

· Translate algorithmic ideas into systems that behave predictably and efficiently in production

· Own and evolve backend services that integrate vehicle models, infrastructure constraints, and geospatial data

· Influence system architecture, algorithmic approach, and operational behaviour

· Take responsibility for solutions from formulation to production use

Who You Are

You are an experienced software engineer with a strong computer science foundation and a background in building complex systems.

You are comfortable with:

· Algorithms and data structures

· Reasoning about complexity, performance, and trade-offs

· Designing algorithms that must work under real-world constraints

· Writing code intended to be maintained, extended, and relied upon over time

· Experience with optimization-heavy systems, algorithmic problem solving, competitive programming, or similar CS-intensive environments is highly relevant.

This role is a good fit if you:

· Want to work deeply with algorithms that matter in daily operations

· Enjoy taking responsibility for complex, long-lived systems

· Like combining theoretical understanding with practical engineering

· Value working with skilled, thoughtful colleagues in a low-ego environment

This Is Us

The team has full ownership of technical direction, including algorithmic choices, system architecture, and technology stack. Senior engineers are expected to actively shape decisions rather than execute predefined solutions.

Our problem domain is informed by scientific research, and we collaborate closely with academic partners. Research is used as input, but success is measured by behaviour in production.

TRATON AB Offers

We offer a dynamic, flexible workplace with hybrid work options, including Scania Sergel and Midway hubs. With a structured development plan and courses, TRATON supports your career growth both locally and internationally.

Benefits include training at our health center Gröndal or wellness allowance, bonus, flexible hours, and company car leasing. The group also hosts events for employees and their families, and Stockholm residents.

Application

Your application should include a CV and any relevant certificates. We welcome all applicants and strive for diversity in our recruitment processes.

Apply as soon as possible, no later than 2026-01-31. Screening will take place on an ongoing basis during the application period. Logical and personality tests may be used as part of the selection process, and a background check may be required for this role.
