What You Will Be Doing
You'll sit at the core of their product, building the systems that make advanced AI usable in the real world.
If you enjoy owning backend services end to end, care deeply about reliability and API quality in a high-impact environment, this role offers both autonomy and real impact.
Requirements Backend Architecture & APIs (Primary Focus) Design and evolve scalable backend services in Python using Fast API for high-availability, high-throughput workloads.
Build well-versioned RESTful APIs aligned to Open API/Swagger, with strong conventions for consistency, idempotency, and backward compatibility.
Implement authentication and authorization using OAuth2/OIDC, session management, and fine-grained permissions.
Design and maintain event-driven architectures and background processing pipelines (e. g.
Celery, Redis Streams, Kafka) to enable scalable async workloads, retries, and fault-tolerant integrations.
Design data models and optimise relational databases (Postgre SQL) for performance, partitioning, and horizontal scale.
Introduce caching, rate limiting, and queuing to meet performance budgets and latency goals.
Integrate with AI pipelines and model-serving endpoints, including streaming responses, async inference jobs, and robust error/retry semantics.
Palantir Foundry Integration Work with Palantir Foundry to build and maintain data pipelines, ontologies, and integrations that connect backend services to Foundry-based analytics and workflows.
Leverage Foundry's APIs and tooling to support data modelling, transformation, and secure data exchange across the platform.
Security & Reliability Write secure, well-tested code (unit, integration, end-to-end) and uphold coding standards through code reviews.
Contribute to logging, metrics, and alerting (Prometheus/Grafana, ELK/Open Search) for the services you build.
Support compliance readiness (ISO 27001, GDPR) through secure-by-default design.
Cross-Functional & Process Collaborate closely with the engineering team, product and leadership to scope, sequence, and deliver outcomes.
Translate product requirements into technical plans, breaking work into milestones with measurable success criteria.
Mentor engineers on backend design and API ergonomics.
Infrastructure Contributions (optional) Ship services via Docker containers with clean, minimal builds.
Contribute to Ia C (Terraform/Cloud Formation) and CI/CD pipelines (Git Hub Actions/Argo CD) alongside the Dev Ops team.
Support cloud operations with sensible defaults, cost awareness, and environment promotion across dev/staging/prod.
Required Skills & Experience SC Clearance or the ability to obtain SC (and later DV).
5+ years of professional software engineering experience, with a strong focus on backend development in Python and with event-driven architectures.
Proven experience designing and operating production REST APIs with Open API/Swagger.
Deep understanding of relational database design, indexing, performance tuning, and migrations (Postgre SQL).
Proficiency with containerisation (Docker) and Git-based workflows.
Experience with API versioning, security, documentation strategies, and automated testing.
Strong problem-solving skills and the ability to work independently with high ownership.
Soft Skills High-agency engineer who owns outcomes end to end.
Pragmatic, research-driven approach with a bias to ship and iterate.
Clear communicator who can talk to stakeholders of varying technical backgrounds. xiskglj
Comfortable defining SLAs, making trade-offs explicit, and operating production systems.
Benefits include:
