We’re looking for a strong technical leader to build and grow a European engineering team around a truly unique robotics and automation platform used in real-world airport operations.

 

This is a rare opportunity for a senior engineer who is ready to become the key technical figure for a new European team and shape both the product and the people around it.

Our client builds cloud software that orchestrates autonomous vehicles and real-world operations in large, complex environments such as airports. Their platform breaks physical processes into digital tasks, coordinates fleets of robots, and enables thousands of operations per day with high reliability. The systems run close to 20 hours a day and are already live in production at major airports. This is not a “demo” or a lab project — it is real software controlling real machines in high-consequence environments.

The goal of this role is to establish and grow the European engineering group from the ground up. You will be the founding member of this team, the main technical owner in Europe, and a core partner to the US-based engineers.

• Ensure all code merged is production-ready and operationally sound
• Participate in weekly release cycles and own production behavior of delivered systems
• Support live deployments at UK airports, including on-site work several times per year
• Act as the founding member of the European engineering group
• Lead hiring, onboarding, and technical ramp-up of new EU team members
• Establish local standards for engineering quality, ownership, and delivery
• Build a strong, trusted collaboration model between EU and US teams
• Lead by example through execution, technical judgment, and accountability

We're looking for

• Senior-level experience building and operating production cloud systems
• Strong proficiency in Python
• Hands-on experience with distributed, event-driven architectures
• Experience working with messaging systems (e.g., NATS or similar)
• Solid background in Kubernetes and cloud-native infrastructure (GCP is a plus)
• Experience with observability, logging, and production telemetry
• Ability to work autonomously with high ownership and responsibility
• Strong communication skills across engineering, operations, and leadership
• Upper-Intermediate or higher level of English, sufficient for confident daily communication with international teams
• Comfort with ambiguity and evolving requirements

• Willingness and ability to travel to the UK for deployments

   

How to knock our socks off

• Experience with Go or Java
• Background in robotics, autonomous systems, or hardware-adjacent software
• Previous experience building or leading distributed teams
• Exposure to real-time or operationally critical systems
• Name five or more dishes that include beets, other than borscht.😉

Who:
We are looking for a Senior Secure Mobile Engineer with deep Flutter expertise and a strong background in applied cryptography and mobile security.

What:
You will build and secure the mobile client in a zero-knowledge architecture, where all encryption, key generation, and sensitive data handling happen entirely on the device.

When:
Immediate start.

Where:
Remote (time zone overlap preferred).

Why:
In a zero-knowledge system, the client is the gatekeeper — if the app is compromised, server security is irrelevant. This role is critical to the security, privacy, and trustworthiness of the entire platform.

Office Environment:
Small, senior-level engineering team focused on privacy, security, and high-impact architectural decisions.

Salary:
Competitive, based on experience and security expertise.

Position Overview:

This role owns the security of the mobile client. You will design and implement encryption workflows, secure storage, memory hygiene, and network protections while ensuring high performance and reliability. You’ll work on advanced cryptographic protocols, offline-first secure data handling, and privacy-preserving AI features — all running fully on device.

Core Technology Stack:

• Languages: Dart (expert), Swift / Kotlin (intermediate, for platform channels)
• Framework: Flutter (deep understanding of rendering engine, Isolates for heavy cryptographic workloads)
• State Management: Riverpod or BLoC (handling ephemeral state wiped on app close)

Key Responsibilities:

• Implement and maintain end-to-end encryption and key management on the client
• Design secure local data storage and lifecycle management
• Build Flutter platform channels for cryptographic and security-sensitive native operations
• Ensure memory hygiene by explicitly clearing sensitive data from RAM
• Implement strong network security protections against MITM and traffic analysis
• Collaborate closely with backend and security engineers on protocol correctness
• Review and harden the app against real-world mobile attack vectors

Crucial Security & Privacy Skills:

• Applied Cryptography:
  • Experience implementing Signal Protocol (Double Ratchet, X3DH) or MLS (Messaging Layer Security)
  • Deep understanding of session setup, replay attack prevention, and key lifecycle management
• Secure Storage:
  • Expert knowledge of iOS Keychain and Android Keystore
  • Experience implementing SQLCipher for fully encrypted local SQLite databases
• On-Device Search:
  • Experience building in-memory, on-device search engines without leaking data
• Memory Hygiene:
  • Writing code that actively clears keys and plaintext from memory after use
• Network Security:
  • Certificate Pinning implementation
  • Experience with Tor / Orbot or similar anonymous routing is a plus
• Local AI Integration:
  • Running on-device LLMs using TensorFlow Lite, MediaPipe, or similar
  • Ensuring AI features (summarization, translation) work offline without cloud data leakage

Ideal Candidate Profile:

• Senior-level Flutter engineer with a strong security mindset
