Senior Unreal Developer| Luxury Automotive Brand Configurator
UK Remote
2-3 Month Contract
£500-600 Per Day

We’re partnering with a studio who are looking for a Senior Unreal Developer to work on an exciting project they’re delivering.

The project is building a real-time, pixel-streamed configurator for a major luxury automotive brand. Users configure a vehicle via a bespoke app. The system then dynamically converts that specific CAD model into Unreal Engine and pixel-streams it back in real-time for a fully interactive, photorealistic 360-degree experience.

What You’ll Be Doing

The Senior Unreal Developer will join the wider Unreal and asset team to take on the core technical challenges around the dynamic pipeline and real-time performance:

• Writing and optimising C++ to handle dynamic model ingestion from the external app into Unreal
• Working with automated CAD-to-Unreal data workflows
• Authoring shaders and materials to deliver luxury-automotive photorealism
• Optimising for a smooth Pixel Streaming experience

What You’ll Need

• Experience working at Senior Unreal Developer level with strong proficiency with Unreal Engine and solid C++ skills
• Experience working with CAD data within Unreal Engine
• Good knowledge of shader programming and high-end material authoring
• Familiarity with Pixel Streaming and real-time performance optimisation

If you’re a Senior Unreal Developer and skills and experience align with the role, click apply.

The role requires close collaboration within an agile software environment, applying strong technical expertise and domain knowledge while communicating effectively with a broad range of internal and external stakeholders. Depending on individual strengths and experience, the role may focus on either modern user interface design and implementation or embedded software development.

For candidates with leadership or line management experience, the position may also include responsibility for managing and supporting team members, reporting on performance, and assisting with resourcing and development.

Responsibilities:

• Producing detailed designs for product software components
• Implementing and testing software as part of an agile development team
• Developing a strong understanding of existing electronic warfare, sensor, and communications products, as well as future development plans
• Contributing to system architecture and continuous improvement initiatives

Candidates should demonstrate:

• A BEng/BSc and/or Master’s degree in Engineering, Computer Science, Information Systems, or a related discipline
• Knowledge of sensor and communication systems
• Experience across the full software development lifecycle, from research and concept through to product delivery
• Understanding of modern software architecture practices
• Experience with scientific or signal processing applications, including algorithm development
• Proficiency in multiple programming languages, such as C++, C#, and Python, with the ability to switch between them effectively
• Familiarity with agile development methodologies, including Scrum and Kanban
• Experience using modern development tools, including Git, GitLab, and Visual Studio Code

Reasonable Adjustments:

Respect and equality are core values to us. We are proud of the diverse and inclusive community we have built, and we welcome applications from people of all backgrounds and perspectives. Our success is driven by our people, united by the spirit of partnership to deliver the best resourcing solutions for our clients.

The Android Platform Engineer will be responsible for:

• Designing, developing, and testing bespoke Android software components
• Working across the full Android stack, including applications, platform services, and system-level code
• Collaborating with cross-functional teams to deliver reliable, high-quality software
• Investigating, troubleshooting, and optimising performance and security issues
• Contributing to software architecture decisions and promoting best practices for Android development

Candidates should demonstrate:

• Strong experience in Android app development using Java and Android Studio
• Exposure to Android or Linux internals

Guidance & Control Software Engineer (Interception Systems)
Location: North London - Hybrid
Type: Contract - Outside IR35
Rate: Starting at 50 per hour DOE

About the Role

Our client develops advanced autonomous weapon and interception technologies designed for high-speed target engagement in contested environments.

The programme centres on a vision-guided one-way aerial system capable of autonomously detecting, tracking, and intercepting manoeuvring objects. The software architecture combines real-time perception with predictive guidance and control.

This role will be central to the development of the onboard flight and guidance stack, implementing estimation, tracking and control algorithms in performance-critical C++ code. The engineer will work closely with perception, simulation and hardware teams to ensure reliable terminal behaviour under real-world conditions.

The Guidance & Control Software Engineer position suits an engineer with experience in missile guidance, air defence, seekers, or high-dynamic autonomous vehicles rather than conventional UAV autopilot development.

Key Responsibilities

Guidance & Control

Develop predictive guidance and control algorithms for autonomous interception

Implement proportional navigation, pursuit guidance or equivalent terminal control laws

Design trajectory prediction and time-to-impact logic for manoeuvring targets

Integrate perception outputs into stable closed-loop control behaviour

Tune and validate behaviour across dynamic envelopes and degraded sensing conditions

Estimation & Tracking

Develop state estimation and tracking filters (e.g. Kalman based approaches)

Handle uncertain and intermittent measurement data

Fuse onboard sensors and vision-derived measurements

Prevent divergence and oscillatory behaviour in terminal phase

Software Implementation

Implement real-time flight software in modern C++

Optimise performance for embedded compute constraints

Support hardware-in-the-loop and simulation environments

Work with safety-critical and deterministic execution constraints

Integration & Testing

Collaborate with perception and simulation engineers

Analyse flight logs and engagement performance

Support ground and flight trials

Debug instability, tracking loss, and intercept miss distance issues

Behaviours

Analytical and physics-driven problem solving

Comfortable working with incomplete or ambiguous data

Collaborative across perception, hardware and systems teams

Pragmatic and delivery focused

Ownership mindset with strong accountability

Calm under test and trial pressure

Qualifications and Experience

Strong C++ experience in embedded or real-time systems

Background in guidance, navigation and control, tracking, or estimation

Experience with high dynamic autonomous or weapon systems

Understanding of control laws and dynamic stability

Experience working with real sensor data rather than purely simulated environments

Familiarity with modelling or simulation environments desirable

Knowledge of vision-based navigation or target tracking beneficial

Degree in Aerospace Engineering, Control Systems, Robotics, Physics, Mathematics or similar

Eligibility to work on defence related programmes in the UK (SC Cleared / 5 years residency in the UK)
