Job details

About the Role We're hiring a Staff Software Engineer to own architecture and design decisions for our platform, including the modernization of legacy enterprise systems into modern, cloud-capable solutions. You'll operate with significant autonomy, act as a force multiplier for the rest of the engineering team, work closely with our Head of R&D as a technical backup, and be a candidate for broader technical responsibility across projects as you prove yourself. This is a hands-on, high-ownership role on a lean, three-person engineering team — small enough that your architectural calls ship and show results in weeks, not after months of committee review. You'll be a player-coach: as comfortable writing code as setting direction, designing and deciding as well as implementing, delegating, and growing the engineers around you. In an AI-assisted development era, we value sound judgment and design thinking as much as implementation speed — you'll have real latitude to use tools like Claude and Cursor to move faster, not just permission to. Responsibilities Architecture & Technical Ownership Own architecture and design decisions for the systems you're responsible for, favoring pragmatic, right-sized solutions over unnecessary complexity, and weighing trade-offs (build vs. buy, hosted vs. on-premises, integration approach) with senior-level judgment. Lead the modernization of legacy systems into maintainable, cloud-capable architectures without disrupting the business relying on them. Review requirements and designs early to flag architectural risk, technical debt, and feasibility gaps before they become expensive. Own solution-level architecture documentation — decisions, trade-offs, and the reasoning behind them — so the system stays understandable at a glance, not just in your head. Hands-On Delivery Design and implement significant parts of the system yourself — this role ships production code, not just plans. Own what you build end-to-end, including its health after it ships — if it breaks in production, you're part of fixing it. Apply AI-assisted development tools (e.g., Claude, Cursor) to work faster across design, implementation, and documentation, with informed judgment about where they genuinely help. Team Leadership & Mentorship Delegate work effectively and help pull the wider team forward, rather than carrying everything yourself. Mentor other engineers through code review, design discussion, and day-to-day guidance, as an individual contributor rather than a people manager. Act as a technical backup to the Head of R&D, and take on broader technical responsibility across projects over time. Product & Customer Judgment Translate ambiguous customer needs — including regulated-industry and enterprise requirements — into sound technical designs. Work closely with product owners, QA, and subject-matter experts to understand how the product is used and where the real risk lies. Communicate trade-offs, risks, and plans clearly to both technical and non-technical stakeholders. Ways of Working Operate independently in ambiguous, shifting-priority conditions, setting your own priorities rather than waiting to be told what's next. This role has no fixed lane — architecture, hands-on coding, mentoring, production support, whatever's needed. You pick it up rather than waiting for it to be assigned. Participate in and help shape Agile ceremonies (stand-ups, sprint planning, retrospectives). Our Stack Frontend: React (TypeScript) single-page applications. Backend: polyglot services, primarily .NET and Python, built as event-driven microservices. Databases: PostgreSQL, SQL Server, and Oracle. Infrastructure: containerized, Kubernetes-based deployments with owned CI/CD pipelines. Deployment model: hybrid — both cloud-hosted (SaaS) and on-premises enterprise environments. API & identity: API gateway / service mesh patterns and OIDC-based identity providers. We're also maintaining and modernizing some longer-standing legacy systems — comfort reading and evolving older architectures is part of the job. What You'll Bring Must-Have 8+ years of professional software engineering experience, including real ownership of architecture and design decisions — not just executing someone else's plan. Proven track record modernizing legacy systems into maintainable, cloud-capable architectures. Full software development lifecycle experience: requirements through design, implementation, testing, release, and operations. Strong relational database fundamentals (e.g., PostgreSQL, SQL Server, or Oracle). Experience in regulated-industry and/or enterprise software environments, with a real appreciation for compliance, data integrity, and audit requirements. Solid grounding in secure coding practices and software design principles. A track record of mentoring or informally leading other engineers — pulling a team forward, not just excelling individually. Excellent written and verbal communication in English, with both technical and non-technical audiences. Nice-to-Have Hands-on experience designing and owning CI/CD pipelines, not just using ones someone else built. Experience with hybrid deployment models — supporting both cloud-hosted/SaaS and on-premises enterprise environments. Experience across more than one of PostgreSQL, SQL Server, and Oracle. Practical, regular use of AI-assisted development tools (Claude, Cursor, or similar) in your day-to-day engineering workflow. A habit of evaluating and adopting new tools and technologies early. Experience designing or shipping AI/ML-powered features in a production application (e.g., using LLMs, cloud AI/ML services, or applied ML) — we're actively exploring how AI capabilities fit into our platform. You'll Thrive Here If You're comfortable operating with autonomy and ambiguity, reasoning from first principles when there's no existing playbook to follow. You're self-directed with a “get it done” mindset — you pick up what's needed rather than waiting for it to be assigned. You want your architecture decisions to matter beyond a single sprint, on a team small enough to notice. Competitive salary aligned to experience and market. Employee profit sharing plan. Fully remote. Comprehensive health, dental and vision insurance. High ownership and autonomy across product marketing initiatives. Opportunity to work directly with leadership in a fast-paced environment. Fast-growing environment with strong long-term career development potential. #S&WTechnologies #TAGSoftwareGroup
