Context

We are building a complex agent that analyzes documents and produces defined data structures extracted from them. Three properties are critical: the structures must be accurate — faithful to the source documents, with exact references and exact quotes; valid — types conforming to their schemas, required fields filled, and so on; and free of duplicates — not repeating structures that were already accepted or rejected before.

Must-have

- 3+ shipped LLM-powered systems in production, each with a measurable quality harness the candidate built personally (golden sets, precision/recall tracking, regression gates in CI). Be ready to walk through one in depth — at whatever level your own NDAs allow — including a concrete regression the harness caught and what changed because of it.
- Proven ability to split model work from deterministic validation: pipelines where extraction is model-driven but every acceptance check (dedup, linkage, schema, rule-conformance) is executable code. Prompt-only quality control is a disqualifier.
- Information-retrieval and data-modeling depth: hybrid exact+semantic indexing; identity-keyed deduplication (record identity over embedding similarity); append-only stores with supersession semantics; incremental re-indexing without full rebuilds.
- Multi-pass agent-pipeline engineering: idempotent, sumable fan-out/verify loops (extract -> validate -> dedup/link -> adversarial verify -> loop-until-dry), token/cost budgeting, caching.
- Evidence-first design method: for every architectural element you propose, you state its precondition and how it is verified; you back your designs with executable acceptance checks against golden sets, not documents alone.

Nice-to-have

- Experience working with and analyzing regulated-domain documents (insurance/finance/legal).
- Event-sourced or lakehouse-style record stores (append-only, versioned, time-travel).
- Knowledge-graph construction and record linkage / entity resolution.
- Adversarial-verification agent patterns (a dedicated verifier stage that tries to refute extractions).
- Custom eval-suite tooling built when off-the-shelf eval frameworks did not fit.

We are looking for a Senior Java Solutions Architect to join a technical discovery and risk assessment engagement, working closely with a UK-based cybersecurity and architecture team on a large enterprise Java estate.

Project: A ten-week discovery and technical assessment engagement for a UK enterprise client, focused on mapping Java runtime usage and dependency risk across an estate of roughly 200 Java endpoints and close to 9,000 related findings.

Responsibilities:

• Build and maintain the Java runtime inventory, confirming actual usage across environments
• Identify components that are unused and removable, that require updating, or that require formal risk acceptance
• Confirm Log4j and Tomcat dependency chains and determine whether they share a common vendor product blocker
• Interpret Veracode Software Composition Analysis (SCA) output to produce an application bill of materials
• Confirm which applications genuinely bundle vulnerable components and assess whether the vulnerable code path is reachable
• Identify components with no direct upgrade path and define remediation options

• Collaborate with client-side architecture and security teams to validate findings and assumptions

   

Requirements:

• 7+ years of experience in Java platform engineering across multiple runtime generations and vendors (Oracle JDK/JRE, JRockit, OpenJDK, Azul, Corretto)
• Hands-on experience upgrading application servers and servlet containers, primarily Apache Tomcat; exposure to WebSphere is a plus
• Proven experience remediating Log4j/Log4Shell exposure in production, including cases where the component is embedded in a third-party product
• Experience resolving transitive dependency and classpath conflicts where the upgrade path is blocked by vendor versioning
• Familiarity with Veracode or a comparable software composition analysis tool
• Strong analytical mindset, able to work confidently with incomplete or conflicting source data

• Upper-Intermediate English or higher

   

What We Offer:

• Transparent strategy and thoughtful management that keep everyone aligned
• Space for personal growth and career development without limits
• A culture of continuous learning: internal courses, workshops, and English classes twice a week
• Skill up events where we share experience and stay on top of trends
• Competitive perks: flexible schedule, a strong compensation package, support for professional certifications, and generous vacation policy
