Senior Software Engineer (Trajectory Planning)

Who are we?

 is enabling the transition to self-driving vehicles through an initial focus on the most commercially advanced sector; the autonomous shuttling of goods and people.

We are home to some of the world’s leading experts on autonomous vehicles, creating solutions such as Oxa Driver, equipping vehicles with full self-driving functionality; Oxa MetaDriver, using Generative AI to accelerate and assure the safety of deployments; and Oxa Hub, a set of cloud-based offerings for autonomous fleet management. Our technology is being deployed across the UK and the U.S, and we’re partnering with a fast-growing ecosystem of operators, vehicle OEMs and equipment makers serving autonomous transportation globally as it advances.

Based in Oxford, and with offices in Canada and the U.S, Oxa was founded in 2014 and is growing rapidly (350+ ‘Oxbots’ to date). Our purpose is to change the way the Earth moves, through an uncompromising focus on safety, efficiency and explainability of our AI approaches. The company has attracted $225 million from leading investors so far, with $140 million raised in the last Series C funding round in January 2023.

Your Team

You will join our Planning Team, where we design, implement, test and deploy the Engine that drives the behaviour of Oxa’s Autonomous Vehicles (AVs), based on its understanding of its environment.

Your Role

As a Senior Software Engineer in Trajectory Planning, you will be responsible for designing, implementing, testing, and deploying algorithms that realise the desired behaviours that the AV needs to exhibit in any particular scenario. Specifically, this role will focus on planning the spatio-temporal trajectories that manifest the desired actions that the AV is executing in the presence of other actors while obeying traffic rules. You will work closely with Decision Making and Controls to plan and execute manoeuvres in a smooth, comfortable, and precise manner.

In this role, you will:

• Collaborate with your Team Lead and team members to solve Spatio-Temporal motion planning problems, including off-the-shelf solver evaluation and custom solver implementation.
• Collaborate with the Decision Making team to transcribe nuanced manoeuvres in complex on- and off-road environments into generalised Trajectory Planning problems.
• Collaborate with the Controls team to ensure Smooth, Comfortable, Precise manoeuvre execution for on- and off-road applications.
• Contribute to the development of high quality functionality and APIs that allow the Planner functionality to be used as a building block for on-vehicle capabilities.
• Create appropriate metrics and tools to measure and benchmark the performance of Planners deployed on various AV platforms.
• Work with customers, stakeholders, and peers to ensure the right solutions are delivered, and actively contribute to resolving disagreements through constructive dialog.
• Contribute significantly to the engineering lifecycle, including scoping, design, implementation, testing, deployment, and maintenance of your team's work.
• Influence technical strategy within the Planning Team, ensuring alignment with your Team Lead and your counterparts in other teams.
• Document and train others on your team's work, focus on improving features, and understand the business and customer value of your team's work.
• Positively impact product quality, customer experience, and maintainability, and take on projects that improve team processes and solutions.
• Contribute to hiring and onboarding at scale by defining role responsibilities and requirements, leading interviews, engaging in recruiting outreach for your team, and mentoring and developing new team members.

What you need to succeed:

• PhD in related field (Mech Eng, Aerospace, Comp Science, Robotics, Mechatronics) with 2+ years of professional experience is desired
• MS in related field (Mech Eng, Aerospace, Comp Science, Robotics, Mechatronics) with 4+ years of professional experience is acceptable
• Extensive hands-on experience of optimisation-based trajectory planning
• Experience with sampling-based trajectory planning approaches
• Experience with trajectory planning problem formulation and problem transcription

• Modern C++ algorithm development and deployment, ideally in a production environment (including STL and common testing frameworks)

Extra kudos:

• Experience with technical and people leadership / management experience
• Dynamic Programming experience
• Knowledge of model Predictive Control, MPC (algorithm)
• Experience with iLQR (algorithm,implementation / utilisation)
• Experience with RRT (algorithm)
• Experience with vehicle dynamics and modelling
• Proven agility in fast-changing environments. As a scale-up, we’re constantly evolving so our people need to evolve too for us to succeed together.
• A customer-centric outlook. Chances are you won’t be directly customer facing, but we value people who anticipate and prioritise the needs of our customers. We call it ‘inventing on their behalf’.
