Our models produce raw per-frame predictions; you own the traditional computer vision, temporal filtering, and inverse kinematics - backed by excellent software engineering - that turn those into clean, rigid, smooth, correctly-calibrated spatial data we can deliver.\nYou'll partner closely with our research teams - you need to understand the models, but you won't be training them.\nYour immediate focus is our 3D hands pipeline, where this work is needed most today. From there you'll be our classical-CV specialist across the organization, brought in wherever geometry, filtering, or pipeline problems come up.\nWhat You'll Do\nOwn the classical 3D geometry that places reconstructions correctly in space: multi-view geometry, triangulation, PnP, camera calibration, undistortion, and reprojection.\n\nDesign and tune temporal filters (low-pass, Kalman-family, interpolation) that remove jitter without losing real motion.\n\nRun inverse kinematics and enforce physical constraints such as bone-length rigidity so reconstructed skeletons stay valid. Build the checks that keep bad frames out of delivery.\n\nTurn model output into clean delivered data, including per-frame results, reports, and the QA metrics that gate delivery, and keep the pipeline running at scale.\n\nBuild visualizers and dashboards to inspect trajectories, overlays, and failure cases.\n\nBe the go-to engineer for classical computer-vision problems across the pipeline as they come up.\n\ngo-to for classical computer-vision problems elsewhere in the pipeline as they come up.\n\nWhat You Bring\n Must-have:\n5+ years of professional experience in software engineering and computer vision.\n\nStrong software engineering. This is a coding-heavy role: clean, efficient, production Python (C++ is a plus).\n\nSolid multi-view geometry: triangulation, PnP, camera calibration, reprojection, and coordinate transforms.\n\nTemporal filtering and signal processing: low-pass and Kalman-family filters, interpolation, and a feel for the trade-off between smoothness and fidelity.\n\nInverse kinematics and rigid-body or bone-length constraints on articulated structures.\n\nEnough ML to work with deep models such as pose and mesh regressors, including their outputs and failure modes, without training them yourself.\n\nA data-quality mindset: comfortable with noisy real-world data and building QA that catches problems before customers do.\n\nNice-to-have:\nHuman pose or mesh reconstruction (hand or body), including keypoint and mesh pipelines.\n\nDepth in Bayesian filtering or state estimation; experience with optimization frameworks such as Ceres or GTSAM.\n\nBuilding CV tooling such as trajectory visualizers and overlay or QA dashboards.\n\nStereo, multi-view, or ego-exo capture experience.\n\nLight temporal ML, such as small networks for smoothing or gap-filling.\n\nA Note on Applying\nStudies show women and candidates from underrepresented groups often only apply when they meet 100% of the listed qualifications, while others apply after meeting 60%. If you don't check every box above but believe you can do the job, we encourage you to apply - we're looking for capability and trajectory, not a perfect checklist match.\nInclusive Hiring at Mecka\nWe are committed to creating an inclusive and supportive candidate experience. Should you require any accommodation whatsoever during the interview process, please inform us without any hesitation. Mecka is dedicated to ensuring equal treatment and opportunity in all phases of recruitment, selection, and employment, in compliance with employment law.

This includes activities such as drafting job descriptions, generating interview questions, note-taking and recordings, and supporting sourcing and scheduling workflows. All candidate evaluations, interviews, and hiring decisions are made by members of the Mecka team. While AI tools may assist with screening and assessment, they do not replace human judgment in selection decisions. Our use of AI is intended to streamline routine tasks, improve consistency, and enhance the overall candidate experience. We are committed to upholding principles of fairness, transparency, and accountability in all hiring activities. Mecka regularly reviews its recruitment practices to mitigate bias and to ensure alignment with applicable laws and evolving best practices.","description_format":"text","description_chars":5426,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Robotic Software & Control Systems"],"lifecycle":[{"event":"open","at":"2026-10-02T07:22:24Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":5,"expected_fill_days":101,"reasons":["conf:2","velocity","win:early"],"computed_at":"2026-10-07T05:47:15Z"},"pay":{"stated_usd_annual":161566,"is_top_pay":false},"html_url":"https://alion.io/job/mecka-computer-vision-engineer-3d","json_url":"https://alion.io/job/mecka-computer-vision-engineer-3d.json","meta":{"generated_at":"2026-10-08T02:34:03Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":4423,"day_limit":5000,"remaining_today":577,"minute_limit":60,"resets_at":"2026-10-09T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":678757},"rest":"https://alion.io/mcp/rest/get_company?id=678757"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmecka-computer-vision-engineer-3d"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fmecka-computer-vision-engineer-3d"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fmecka-computer-vision-engineer-3d"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/mecka-computer-vision-engineer-3d\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmecka-computer-vision-engineer-3d"}]}
