You will own core “Mastermind” modules, transforming high-level decision engines—including symbolic task planning and behavior trees—into high-performance, real-time C++ for edge compute. Working directly with the CTO in a team of four, you will take autonomous systems from prototype to deterministic field trials on real flight hardware.
Robotics Software Engineer at Mutable Tactics
Mutable Tactics is building the orchestration layer for autonomous robotics, and they need a Robotics Software Engineer to own the decision-making "brain" of their multi-robot fleets. Join a pre-seed team of four in Cambridge to turn symbolic task planning and behavior trees into high-performance C++ running on edge compute. If you have deep experience in PDDL or POMDPs and want to see your code fly in real-world trials, this is your chance to have direct ownership of a core system from day one in an elite robotics startup.

Role overview
Mutable Tactics is a UK-based deep defense-tech startup developing an edge-deployed AI orchestration layer for autonomous robotics. Its flagship product, Mastermind, is designed to coordinate mixed fleets of unmanned systems and convert inexpensive, third-party robotic platforms into a unified team that can operate in degraded, denied, or communications-limited environments while preserving meaningful human control. The company describes its technology as combining sensing, reasoning, and compute at the edge to enable coordinated multi-robot missions and explainable autonomy.
What you will do
- Design and implement core modules in modern C++ (17/20) for task execution, world-state management, and platform adapters for autonomous vehicles.
- Develop the reasoning side of the world model by abstracting fused perception tracks into symbolic states for the PDDL-based decision engine.
- Integrate partner platforms using MAVLink and ROS 2, leading field trials and ensuring deterministic performance on hardware like NVIDIA Jetson.
Who this is a fit for
- Extensive production experience in modern C++ (17/20) focusing on concurrency, memory ownership, and performance profiling for real-time robotic systems.
- Deep technical background in symbolic task planning (PDDL), behavior trees, or decision-making under uncertainty (POMDPs) for real-world applications.
- Proven track record of shipping software for real physical robots using ROS 2 and Linux, with eligibility for UK SC clearance.
Why this role is remarkable
- Directly architect the decision-making “brain” of multi-robot systems, moving beyond simple simulation to real-world flight trials and field operations.
- Join an elite founding team of four in a pre-seed environment where your technical decisions immediately shape the core product and company trajectory.
- Solve the complex problem of coordinating heterogeneous robotic fleets under real-world uncertainty, sensor degradation, and mission-critical time constraints.
