Greenhouse · LinkedIn | AI: 0.07 | GH fraud: weak (+4 weak: country mismatch, proxy, bot-like IP, new email) | ⚠ Potential duplicate

This candidate shows genuine technical depth in exactly the stack Mattermost needs: Go/TypeScript full-stack work on a production ChatGPT App integration, PostgreSQL query optimization with measured before/after latency, and REST/WebSocket API design at meaningful scale (4,200 concurrent sessions, 300K-vehicle inventory). The AI-agent answer is concrete and credible — daily Claude Code/Cursor use for test scaffolding and refactor candidates, reviewed in weekly code review, with a quantified zero-regression claim and evidence of mentoring others on the workflow, which directly matches the role’s ‘core required skill’ bar rather than just checking a box. Career trajectory (Barclays -> Tailor Brands -> WeWork -> Turo, Staff-level) shows steady seniority growth and some enterprise/compliance exposure (encryption at rest/in transit, SOC 2 mentioned on resume), which is a plus for the regulated-environment nice-to-have. Two things worth flagging before an outreach: the stated ‘8+ years’ self-reported experience doesn’t reconcile with a resume spanning 2011-present (13+ years) and a resume summary claiming ‘15+ years’ — worth clarifying in a screen, as it’s a moderate inconsistency rather than a disqualifier. More importantly, there’s no evidence in the application of US government clearance eligibility, ITAR/EAR status, or defense/intelligence domain exposure, all of which are hard requirements here — this should be confirmed early since it could be a gating issue regardless of technical fit. Net: strong technical and AI-workflow match, recommend a screen focused on clearance/citizenship eligibility and experience-timeline clarification.

#1 · Joshua Lytle · Issaquah, Washington, United States · Principal Software Engineer · NomadGo, Inc. · score: 0.871

Greenhouse · LinkedIn | AI: 0.14 | GH fraud: strong — datacenter IP (+3 weak: proxy, bot-like IP, IP history)

This is a strong technical match: the candidate has shipped iOS since 2008 and cross-platform (including React Native SDK work) since 2011, with recent hands-on experience building connectivity-loss handling (startup, sign-in, count submission) and MDM/managed-app-configuration support for store devices at NomadGo — essentially a dry run for the DDIL and enterprise-distribution requirements in this role. They also show real performance engineering chops (adaptive inference throttling and OCR interval gating to cut AR scanner battery drain) and testing/CI discipline (1,000 unit tests, 100 automated UI tests, built partly with agentic tooling), plus prior SDK work integrated by major retail engineering teams (Target, Lowe’s, Staples, Macy’s), evidencing experience shipping code others depend on.

#1 ★NEW · Pierre Cabell · Cuyahoga Falls, Ohio, United States · Staff Full-Stack Engineer · UVeye · score: 0.889

Greenhouse · LinkedIn | AI: 0.12 | GH fraud: strong — datacenter IP, VOIP phone (+5 weak: TZ mismatch, proxy, bot-like IP, IP history, new email)

This candidate is a strong match on paper: current Staff title at UVeye doing exactly the described work — Go/React/TypeScript/PostgreSQL/Redis, architecture ownership across four product teams, a real-time WebSocket layer with explicit reconnect/ordering/backpressure design, and a documented testing overhaul (48min to 14min pipeline). The AI-agent story is specific and credible rather than buzzword-y: shared Claude Code skills, MCP servers for internal APIs, a CI review agent adopted org-wide, and explicit written guardrails for where agents shouldn’t touch auth/payments/security — this is genuinely above-average AI-tooling maturity for a staff-level hire. Mentoring and informal-influence answers are concrete (named outcomes: one engineer now leads API redesign, another runs a testing guild) rather than vague self-praise, and the regulated-environment experience (ITAR, FedRAMP-aligned controls, air-gapped military deployment) is a near-exact match to the ‘regulated/high-compliance’ and EAR/ITAR requirements.

Greenhouse · LinkedIn | AI: 0.13 | GH fraud: strong — datacenter IP (+4 weak: proxy, bot-like IP, IP history, new email) | ⚠ Potential duplicate

This candidate presents a strong technical match for the role: current hands-on experience with Go, React/TypeScript, PostgreSQL, WebSockets, and Redis, plus explicit daily use of Claude Code and Cursor for test generation, refactoring, and even building custom MCP servers for agentic workflows — directly matching the ‘AI-forward’ requirement rather than just checking a box. The resume also shows relevant enterprise/security-adjacent work (tenant isolation, role-based access control, compliance hardening) which aligns well with Mattermost’s regulated-environment context, even though there’s no explicit defense/intelligence domain experience or mention of security clearance status, which should be confirmed directly.

#1 · Jonathan Pyers · Troutman, North Carolina, United States · Solution Architect and Team Lead - Senior Software Engineer, Full-Stack · RTS Labs · score: 0.859

Greenhouse · LinkedIn | AI: 0.07 | GH fraud: ok

This is a strong match on paper: genuine Go + React/TypeScript production experience, PostgreSQL, a track record of end-to-end ownership (solution architect scoping and delivering client systems, MCP server for company-wide estimating), and real regulated-environment exposure — five years at Lawrence Livermore National Laboratory supporting mission-critical National Ignition Facility operations, plus HHS government consulting at Ad Hoc. The LLNL background strongly suggests clearance/ITAR eligibility even though not explicitly stated, which directly addresses a required qualification many candidates can’t meet. The AI-agent fluency signal is unusually credible — they didn’t just name a tool, they built their own agent harness (public repo) and actively maintain standards artifacts for agents across projects, which is close to the ‘org-wide AI-agentic engineering standards’ this role wants someone to establish.
