About The Company DiDi's autonomous driving unit was established in 2016 with the mission of developing Level 4 autonomous driving (AD) technology to make transportation safer and more efficient. In August 2019, the unit became an independent company, DiDi Autonomous Driving, dedicated to advanced AD R&D, product application, and business expansion. We believe integrating AD technology into a shared-mobility fleet will generate immense social value. By leveraging DiDi's specialized technology, operational expertise, and integrated ecosystem, we are positioned to build and operate a highly efficient, user-oriented autonomous fleet. About The Role We are seeking a motivated PhD graduate with a strong research background in motion planning, robotics, or autonomous systems. In this role, you will apply your expertise in algorithm design and system integration to help develop next-generation planning capabilities for autonomous vehicles. Responsibilities Implement novel solutions for Behavioral Planning, enabling high-level decision-making for lane changes, merges, yields, and multi-agent interactions. Design and optimize motion planning algorithms that integrate geometry-based path reasoning and context-aware speed reasoning into smooth, safe trajectories. Develop and improve core geometry and velocity planning systems to ensure feasibility, compliance, and comfort across diverse driving scenarios. Model complex driving environments and agent behaviors to create a robust world representation for planning under uncertainty. Formulate cost functions and optimization frameworks that balance safety, comfort, and efficiency in trajectory selection. Analyze, test, and debug system performance through simulation and real-world data, conducting root-cause investigations and proposing enhancements. Collaborate with researchers and engineers across Perception, Prediction, and Control to ensure an integrated, reliable autonomy stack. Qualifications Recently completed or soon-to-complete PhD in Robotics, Computer Science, Electrical Engineering, or a related field. Research or Internship experience in one or more of the following: Motion planning algorithms (optimization, sampling, graph/search-based methods) Behavioral planning and decision-making under uncertainty Trajectory optimization and control Multi-agent interaction modeling Proven research ability demonstrated by publications in top-tier conferences (e.g., RSS, ICRA, IROS, CVPR, NeurIPS, CoRL). Hands-on experience in C++ for implementing complex, real-time algorithms. Excellent analytical and communication skills, with a collaborative mindset. For Internship Applicants: This role offers a clear pathway, with top-performing interns receiving the opportunity to convert to a full-time engineer upon successful completion of the program. The hourly rate for the Intern position in the selected city is $46. Interns will also be eligible for Intern benefits. Applications are accepted on an ongoing basis. This posting is for an existing vacancy.

Here's how to pick the right one and stand out in your application.
144.883Jobs

That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
