Employment Type: Full-time

What you can expect as a Senior Software Engineer - AI Platform at Fortress: 

Fortress Information Security is seeking a Senior Software Engineer, AI Platform to help build the foundational AI platform powering intelligent workflows across Fortress products and services. This role focuses on designing and operating the orchestration, retrieval, execution, and platform infrastructure required to support scalable, secure, and reliable AI systems in highly regulated environments.

The ideal candidate brings strong distributed systems and backend engineering experience combined with hands-on experience building production-grade AI infrastructure, orchestration systems, or retrieval platforms. This individual will work across platform, infrastructure, and application layers to help establish the technical foundation for Fortress’s AI strategy.

This role is well-suited for engineers who enjoy solving complex systems problems involving long-running stateful workflows, multi-store retrieval architectures, event-driven systems, observability, and secure multi-tenant infrastructure. Please note: This role is built for a true, current senior engineer. Someone who hits the ground running, drives decisions independently, and raises the bar for the team from day one.

Responsibilities Include:

Design, build, and operate orchestration frameworks supporting long-running, stateful AI workflows and agent execution systems

Develop distributed retrieval architectures spanning vector, graph, search, and relational data platforms

Build shared platform services, reusable runtime components, and tool registries supporting AI capabilities across Fortress products

Implement resilient event-driven and change-data-capture (CDC) pipelines with strong consistency, retry, and fault-tolerance guarantees

Develop typed APIs and integration contracts supporting AI workflows and platform interoperability

Improve scalability, performance, reliability, and operational efficiency across orchestration and retrieval infrastructure

Support secure multi-tenant deployments across cloud, hybrid-cloud, and air-gapped environments

Build and maintain observability, telemetry, tracing, centralized logging, governance, and policy enforcement tooling

Contribute to engineering standards and architectural patterns for orchestration, retrieval, and platform infrastructure

Collaborate cross-functionally with platform engineering, product engineering, security, and AI teams to support platform adoption and operational excellence

Participate in troubleshooting, incident response, root cause analysis, and operational support activities related to platform infrastructure

Continuously evaluate emerging technologies, tooling, and engineering practices relevant to AI infrastructure and distributed systems

Minimum Qualifications:

6+ years of experience in backend, platform, or infrastructure engineering building production distributed systems

Strong Python development experience including asynchronous systems, API design, and typed architectures

Experience designing and operating scalable distributed or service-oriented systems in production environments

Hands-on experience building or operating AI infrastructure, orchestration systems, retrieval platforms, or modern RAG architectures in production

Strong understanding of distributed systems concepts including queues, event streams, retries, consistency models, concurrency, and fault tolerance

Active daily use and fluency with AI-assisted engineering workflows and agentic development tooling such as Claude Code, Cursor, or similar platforms, including effective use of LLMs throughout software design, implementation, debugging, and operational workflows.

Strong written and verbal communication skills with the ability to collaborate effectively across technical teams

Ability to operate independently in fast-moving, highly technical environments with evolving priorities

Preferred Qualifications:

Experience with orchestration and workflow frameworks such as LangGraph, Temporal, Celery, or similar technologies

Experience with vector databases, graph databases, search platforms, and modern retrieval architectures involving embeddings, hybrid search, reranking, or knowledge graph traversal

Experience with event-driven architectures, CDC pipelines, or streaming platforms such as Kafka, Pulsar, or pg-boss

Experience with observability and telemetry tooling such as OpenTelemetry, Prometheus, Grafana, or centralized logging platforms

Experience deploying and operating systems within regulated, high-security, hybrid-cloud, or air-gapped environments

Familiarity with secure software supply chain practices, signed artifact distribution, and multi-tenant platform isolation strategies

Contributions to internal developer platforms, reusable infrastructure tooling, or shared engineering frameworks

Experience mentoring engineers and contributing to engineering standards and architectural best practices

Education:

Bachelor’s degree in Computer Science, Software Engineering, Information Systems, or a related technical field preferred. Equivalent combinations of professional experience, technical training, certifications, or demonstrated expertise will also be considered.

Who thrives in this Role:

This team moves fast, operates with high autonomy, and builds things that don't exist yet. Engineers who do well here are genuinely deep in AI infrastructure, treat AI-assisted development as a core skill they're actively improving, and prefer building over debating. They own their outcomes without being pushed and find constrained, regulated environments interesting rather than frustrating.

If you've been building in this space on your own time and want to work somewhere that takes it seriously, this role is for you.

This role is not for you if...

You're drawn to AI but haven't actually built anything in the space.

You treat AI development tools as a novelty rather than a daily practice.

You do your best work with clear roadmaps, stable requirements, and plenty of process.

You want to architect and delegate rather than write the code yourself.

You need direction to get moving.
