An engineering job description should tell someone what they will own, why the work matters and what joining involves. Lead with the problem and the responsibility, then make the technical requirements, compensation and working arrangement easy to find.
That is more useful than a list of adjectives or every technology the company has ever used. An engineer should be able to recognise the work, assess their experience against it and identify the questions they need to ask.
Start with the founding engineer hiring brief if the role is still unclear internally. Copy cannot resolve a disagreement about what you need. The approach below is Corellia Talent’s recommended writing and review process.
Agree the role before describing the person
A useful advert begins with a decision about the work. Name the problem the hire will address, the decisions they will own and the colleagues they will work with. Explain what exists today and what needs to become different.
Then write the requirements. Ask what someone must be able to do at the start and what they could learn with the support available. If a requirement cannot be connected to the work, challenge whether it belongs in the advert.
Be precise about seniority. A senior title with little decision authority creates a different role from a senior title with responsibility for a whole product area. The technical leadership mandate guide helps distinguish individual contribution, team leadership and wider organisational responsibility.
Put the engineering problem near the top
The opening should explain the job without making the reader work through a company history. Name the product or system, the immediate challenge and the scope of ownership. Describe the business in a few factual sentences after that.
The following is an illustrative rewrite, not a description of an employer or a live vacancy.
Vague: “We need a passionate engineer to work on exciting projects in a fast-paced team.”
Specific: “You will own the service that turns customer data into a usable product feed. The first priority is making imports recover cleanly when an upstream source fails. You will work with product and the engineers responsible for storage and the customer interface.”
The second version gives the conversation somewhere to go. A candidate can discuss reliability, ownership and collaboration. It also gives the interview team something concrete to assess.
Explain ownership through decisions
“End-to-end ownership” needs an explanation. Does the person choose an approach, write the implementation, operate it and speak with users? Which decisions need review? Who helps when priorities conflict?
Use a short set of responsibilities that describe outcomes and boundaries. Avoid repeating generic activities such as attending meetings or collaborating with colleagues unless the particular collaboration explains the role.
For example, a product engineer may work directly with a customer-facing colleague to understand recurring failures. A platform engineer may agree a migration with several product teams. A research engineer may turn experimental results into repeatable infrastructure. These are different responsibilities, even when the same language appears in the stack.
If you are hiring across AI disciplines, use the AI and research role guide to separate the work before combining titles in one advert.
Separate essential experience from useful familiarity
Requirements should help the right person recognise a fit. Keep the essential list focused on the capability needed to do the job. Put useful familiarity in a separate, shorter section.
Distinguish learning a tool from learning a discipline. An engineer may be able to learn another web framework while still needing substantial experience in distributed systems for the role you are filling. Explain which underlying judgement matters.
Avoid turning the entire stack into a screening checklist. Say which technologies are central to daily work and where equivalent experience is welcome. If a qualification or specific background is required, be able to explain why.
Read the list against the responsibility section. If the candidate needs to be a product designer, infrastructure specialist, applied scientist and engineering manager to meet it, you may have described several hires rather than one.
Make salary information usable and compliant
Salary information should identify the currency, pay period and genuine range for the role. Separate base salary from bonus, equity and other benefits so a reader can understand each component.
For California postings, official guidance says employers with at least 15 employees must include the pay scale when a position may be filled in California, including remotely. The Labour Commissioner’s interpretation requires at least one employee in California when applying that headcount test. The pay scale is the salary or hourly wage range the employer reasonably expects to pay. [Source 1]
New York City guidance covers employers with four or more employees where at least one works in the city, and employment agencies regardless of size. Covered adverts must include a good-faith minimum and maximum for work performed wholly or partly in the city. State requirements may also apply; check the state guidance as well as the city rules. [Sources 2 and 3]
Use the actual approved range, not an expansive theoretical band that combines unrelated levels. Check that the job board, recruiter brief and company page describe the same role. For compensation context, the salary guide distinguishes observed adverts from modelled estimates.
Describe equity without hiding the salary
Equity should be presented as a separate part of the package. State what can be shared at this stage and what will be explained during the process. Do not imply that an equity grant is guaranteed cash.
Candidates may need to understand the instrument, vesting, exercise terms and the basis of any percentage. Make sure the team can explain the terms it offers rather than leaving the recruiter to interpret them.
If the details are not ready, resolve them before making an offer. The advert can describe an equity component accurately without attaching an invented value. A clear base range remains useful even when the final equity terms depend on the appointment.
State the working arrangement in plain language
Location should describe where the work happens. For a hybrid role, name the office location and required attendance. For a remote role, name the eligible locations, overlap expectations and any planned travel.
Avoid wording that sounds flexible while concealing a fixed requirement. If the role requires regular work with physical equipment or customers, explain that. If relocation is necessary, say when and what support is actually available.
Working hours and on-call expectations also matter. Give candidates enough information to decide whether the arrangement is practical before they invest in several interviews. Do not leave an important condition for the final conversation.
Show candidates how the process works
A short process outline reduces avoidable uncertainty. Explain the main conversations, whether there is a practical assessment and who makes the hiring decision. Keep the outline aligned with the process the team can actually run.
State the expected time commitment for an exercise once it is agreed. Tell candidates what tools they may use and how the work will be discussed. Give them a route to request adjustments or ask questions about the format.
If the process changes, explain why. A job description is part of the promise made at the beginning of a search; the conversations that follow should make the role clearer, not reveal a different job.
Check the advert against an engineer’s questions
Before publishing, ask someone who understands the work to read the advert without the internal brief. Can they explain the main problem, the level of authority, the skills that matter and the conditions of joining?
Then run a practical review:
- Is the title a recognisable description of the role?
- Does the opening explain the work rather than praise the business?
- Are required and useful skills clearly separated?
- Are pay, location and attendance consistent across every channel?
- Is the assessment relevant to the responsibilities?
- Does the application link work, including on a phone?
Give one person responsibility for keeping the advert current. If scope or compensation changes, update the original page and the copies shared elsewhere. Track the questions candidates repeatedly ask: they often reveal the next sentence your description needs.
Use the description to start a better conversation
A strong job description is specific enough to support a thoughtful reply. An engineer can recognise a relevant problem, explain comparable work and ask about the decisions they would own.
Use the same clarity in outreach and interviews. Ask about evidence connected to the brief, make the trade-offs visible and leave room for the candidate to assess your team. Better information gives both sides a more useful starting point.
