Senior Backend Engineer (Telco Integration Lead) We are seeking a deeply technical and security-minded Senior Backend Engineer to join a newly-founded, high-impact AI joint venture. Backed by five of the world's leading telecommunications giants, our mission is to restore trust in global voice communication. This is not a standard backend role. We are seeking a foundational engineer to own our single greatest strategic asset: our unique, privileged access to network-level intelligence via the GSMA CAMARA API standard. This is our “right to win”, and you will be the engineer responsible for building the bridge to it. You will be the Critical Path Owner for Track Zero, the 30-day foundational sprint to validate and integrate the first-ever CAMARA-based signals (like sim-swap and device-roaming-status) from our telco founders. Your success is the Go/No-Go gate for our MWC 2026 launch. You will be directly responsible for building the “out-of-band” data path that enables our flagship Telco-Verified Security Shield and its sub-500ms “Time-to-Trust” metric, our core differentiator that no “over-the-top” competitor can replicate. This position offers a unique opportunity to define a new category of network-aware security, working directly with the world's leading carriers to turn their network data into a real-time defense against global fraud. Key Responsibilities Telco Integration & Architecture • Own and build the Security Signal Ingestion path, the secure, low-latency, and out-of-band data channel connecting to our founding members' network API gateways., • Architect and implement a carrier-agnostic, vendor-agnostic connector layer to consume RESTful APIs from a heterogeneous global landscape of telco partners and IMS vendors (e.g., Nokia, Ericsson, Mavenir)., • Serve as the primary technical liaison to the engineering teams at our telco founders (Deutsche Telekom, Singtel, SKT, etc.), working “hand-in-glove” to navigate, validate, and productionize their new CAMARA network APIs., • Design and build the high-throughput microservices that will query, ingest, normalize, and cache network signals (e.g., sim-swap, device-roaming-status) to be used in our real-time Scam_Score model., • Implement a mandatory Zero Trust security model for this critical integration, our most sensitive asset. This includes mTLS, least-privilege IAM, and network micro-segmentation. System Ownership & Performance • Serve as the Critical Path Owner for Track Zero, our 30-day sprint to validate and integrate real-time signals from at least two telco partners, culminating in a Go/No-Go demo., • Ensure all network API integrations meet the stringent P99 latency budgets (e.g., < 150ms) required to support our sub-500ms Time-to-Trust product goal., • Collaborate with the platform team to build a parallel development path using mocked data to mitigate risks of network API delays., • Define and own the data contracts and pipelines that feed this "ground-truth" network data from the integration layer to our core AI Service Bus (Apache Kafka). Cross-functional Collaboration • Work closely with the Scam Detection Service and AI/ML teams to define the feature vectors and data payloads needed from the network to power our proprietary machine learning models., • Partner with product and leadership to define the Phase 2 (post-MWC) roadmap for co-developing new, proprietary network APIs (like Caller_Velocity from CDRs) that will become our long-term, indefensible moat., • Document integration architectures, data schemas, and security controls to create setup guides for our Founding Member partners., • Collaborate with our external InfoSec vendor to ensure the integration layer is continuously validated and hardened against threats. Required Qualifications Education & Experience • Bachelor's degree in Computer Science, Engineering, or a related field., • 7+ years of hands-on experience in backend engineering, with a proven track record of building and maintaining high-performance, distributed systems in production. Required Technical Skills • A minimum of 5 years of production experience with Go (Golang). Experience in other languages (e.g., Python, Node.js) is valued, but will not replace this core Go requirement., • Strong, demonstrable experiefnce with real-time, low-latency data processing. You obsess over milliseconds and understand the trade-offs., • Proficiency with cloud platforms (AWS, GCP, or Azure) and containerization technologies (Kubernetes, Docker)., • Deep understanding of API design (REST, gRPC, Webhooks) and API security (OAuth 2.0, mTLS, JWTs)., • Knowledge of (or deep, demonstrable curiosity about) telecommunications protocols and architectures. You must be comfortable talking to network engineers., • Experience with high-throughput messaging or streaming platforms (e.g., Kafka, Pulsar). This is a permanent position with hybrid working of two days a week in the central London office and the rest WFH. The salary is very much dependant on experience with a guide between £110k-£140K basic + package.

Our Mission Synthax is a VC-backed, early-stage AI HealthTech startup co-founded by our CTO (Mark) and our CEO (Dr Shaheer). We are building an AI platform to replace the patchwork of outdated healthcare systems with one unified, automated solution for clinics. We want to eradicate healthcare inefficiencies with AI at scale. Our Vision We’re building a “clinic-in-a-box” where a single clinician can operate with the capabilities of an entire team.
