Senior Software Architect — AI-Driven Modular Platform

OEC; Poland; On-site; PLN 240,000 - 420,000; Full time

Job summary

OEC Analytics is seeking a senior software architect to own module boundary models and architect multi‑project backends with strict isolation and contracts‑only dependencies. You will drive ADR governance, author playbooks, and shape the shared platform library for eventing, mediation, auditing and observability.

Partner with tech leadership on roadmaps, enforce architecture tests in CI, and mentor engineers on platform conventions, domain pack extensibility, and secure, scalable AI-enabled

Qualifications

• 7+ years of software development experience with hands-on architectural work in modular or SOA backends.
• Strong command of .NET/C#, ASP.NET Core, EF Core, and enforcing dependency-direction rules across multi-project solutions.
• Experience writing ADRs or equivalent lightweight decision records; excellent written communication is essential.
• Partner with tech leaders and product management on roadmap alignment.

Responsibilities

• Owns the module boundary model — isolation, contracts-only dependencies, composition roots — as specs precise enough for agents to implement, and architecture tests that enforce them in CI.
• Drives the ADR process, and audits for drift between documented decisions and real implementation, including agent-generated code.
• Authors the playbooks coding agents work from, reviews their output against spec, and decides which changes — schema, cross-module contracts, security — need human sign-off.
• Grows the shared platform library (eventing, mediation, auditing, observability), driven by real module needs rather than ported wholesale.
• Defines how non-deterministic output is verified — an eval harness in CI that gates prompt and model changes.
• Defines and governs the domain pack extensibility model, including the semantic definitions the AI Analyst reasons over.
• Gatekeeps new module and pack proposals, assessing integration cost, reuse, and capability-inventory fit before implementation begins.
• Scouts and justifies new technologies and methodologies, including AI and agentic tooling, for adoption at OEC.
• Escalation point for cross-team design issues; mentors engineers on platform conventions and on writing agent-ready specs.
