Agentic Development Platform Engineer

Archer is collaborating with Leo Technologies to connect them with exceptional professionals for this role.
Description
GET TO KNOW US:
LeoTech is leading the effort to assist public safety efforts around the nation. We bring industry expertise and innovative technology to address real-world problems public safety agencies face every day.
Our search and analytics platform, Verus, has been used to assist in homeland security, provide assistance for mental health, and increase safety and awareness of public safety.
Everything we do and build is aligned with our mission and the goals of our public safety partners. We work hand-in-hand to build technology solutions that drive the future of public safety.
The Role
We're redesigning how software gets built. Our engineering organization has moved to cross-functional pods using spec-driven development with Claude Code and OpenSpec. We treat the development process itself as a product that has to earn trust from engineers, customers, and auditors alike.
We're hiring two engineers to build, run, and continuously improve the agentic development lifecycle (ADLC) platform underneath that work. The platform includes the shared harness and skill library, the evaluation and observability pipelines, the security controls, and the automation that turns every change into SOC2 Type 2 and FedRAMP High evidence. Our goal is to enable engineers to supervise coordinated agents delivering multiple product features in parallel, with clear human accountability for architecture, quality, and final acceptance.
This is a software-engineering role with a platform specialty. You will deliver real product changes with pods and use that work to validate and improve the shared development system.
What You Will Do
Build the agentic development flywheel
Design orchestration that decomposes approved specifications into tasks, assigns specialized agents, and coordinates dependencies and handoffs across implementation, testing, review, and documentation.Enable concurrent feature work across repositories using isolated branches, worktrees, and environments. Manage shared dependencies, conflicts, concurrency limits, and integration through reviewed pull requests.Create human checkpoints and escalation paths for architecture, product decisions, sensitive actions, and final acceptance. Product teams retain ownership of their systems and domain decisions.
Build and run the platform
Design, build, and operate the shared agentic engineering harness used by every pod. This covers Claude Code configuration, system prompts and rule files, hooks, subagents, MCP server connections, and OpenSpec templates and workflows. Keep models, coding agents, and orchestration tools replaceable through stable interfaces.Own the shared skill library as production code: versioned, pinned, reviewed in PRs, tested in CI, and distributed to every repository.Build context systems that give each agent accurate, task-relevant repository knowledge, architecture, domain rules, specifications, and prior decisions within appropriate context and access limits.Build and maintain evaluation pipelines. For skills, that means trigger accuracy, execution, regression, and token-budget evals. For agent work, it means trajectory-aware and final-output evals. Run fast checks in CI with minimum pass thresholds and broader scheduled evaluations for deeper regression, quality, and cost testing.Instrument agent runs with end-to-end tracing of sessions, agent trajectories, tool calls, context, outputs, failures, retries, and handoffs. Add cost and token metering, and sample so that failures and runaway loops are always kept. Apply appropriate redaction, access controls, and retention to traces.Keep the platform highly available across environments. Debug agent failures across the stack, including context overflow, tool misrouting, and self-repair loops that burn budget without progress. Build bounded retries, checkpointing, resumability, cancellation, and idempotent tool actions so partially completed work can recover safely.
Continuously improve the tooling
Join pods for targeted product initiatives and deliver selected changes from specification through testing, deployment, and operation. Use these outcomes to validate agent workflows and identify reusable improvements.Use eval results, traces, and delivery metrics to find where the harness is failing engineers, and then fix it. Turn recurring failures into regression cases and validated improvements into shared context, skills, and workflows.Maintain the skill library over time. Harvest proven workflows from successful traces into new skills, tune skill descriptions for trigger accuracy, and retire skills that don't earn their context cost.Run bounded experiments on harness changes such as models, prompts, skills, and tools. Ship only what measurably improves outcomes without regressing the existing suite.Partner with pods to capture domain knowledge as skills. Review and promote pod-contributed skills through the same eval and deployment gates as platform-owned ones.Build shared default workflows for AI tooling across repositories, including evaluating tools and making procurement recommendations. Give pods room to experiment and promote proven patterns when they reduce repeated work, cost, or risk.
Secure and govern agent activity
Enforce least privilege for agents through dedicated agent identities, scoped short-lived credentials, and permission policies per agent and environment.Harden the tool layer. Vet and allowlist MCP servers, defend against prompt injection and spoofed tools, and add deterministic hooks and policy checks before high-risk actions.Integrate SAST, SCA, secret scanning, and security review tuned to the failure modes of AI-generated code into CI.Maintain context hygiene so that PII, secrets, and other sensitive data stay out of agent context and outputs.
